In some embodiments, processing demands of a server system can be monitored. In response to determining that a boost mode is needed to support processing demands of the server system or detecting a component being a bottleneck in processing pipelines of the server system, a boost activation signal can be generated.

## Background
TECHNICAL FIELD
The present technology relates generally to server systems in a telecommunications network.
BACKGROUND
Modern server farms or datacenters typically employ a large number of servers to handle processing needs for a variety of application services. Each server handles various operations and requires a certain level of processing capacity to handle these operations.
However, processing requirements on a particular server may vary from time to time. Sometimes, central processing units (CPUs) on the particular server may be temporarily overclocked to handle a burst of processing demands. During the overclocking, the CPUs may demand additional power from power supplies of the particular server. Thus, there is a need to provide a system and method for temporarily boosting power supplies to satisfy the additional power demand from the CPUs.
SUMMARY
Systems and methods in accordance with various embodiments of the present technology provide a solution to the above-mentioned problems by storing electrical energy in an energy storage (e.g., one or more buffer capacitors, one or more batteries, or a combination thereof) to support a boost mode of a server system. More specifically, various embodiments of the present technology provide methods for boosting a voltage differential of an energy storage by using a boost component, determining a server system being switched to a boost mode, and discharging the energy storage to provide additional power supplies to the server system during the boost mode.
In some embodiments, one or more components of the server system can run at a higher clock speed for a short period of time during a boost mode. For example, a central processing unit (CPU) of the server system can operate at a higher clock speed during the boost mode, which may cause the CPU to consume more power and produce more heat.
In some embodiments, processing demands of a server system can be monitored. In response to determining that a boost mode is needed to support processing demands of the server system or detecting a bottleneck component in processing pipelines of the server system, a boost activation signal can be generated. In some implementations, the boost activation signal can be analog, digital, or a combination of both. The boost activation signal can cause a CPU, the bottleneck component, or another component of the server system to operate under a higher clock speed such that a higher processing capacity can be achieved.
In some embodiments, a boost activation signal can cause an energy storage to supply stored electrical energy to other components of the server system. In some implementations, supplying stored electrical energy can cause a voltage differential over the energy storage to be reduced from a first voltage to a second voltage. In response to a boost mode of the server system being ended, the energy storage can be recharged by a power supply unit (PSU) of the server system.
In some embodiments, two or more boost modes can be provided on the server system to balance power consumptions and computation speeds of the server system in a specific boost mode. For example, one specific boost mode can last longer but provide less computation speeds and consume less powers comparing with those of another boost mode. In some embodiments, a maximum time period of a specific boost mode can be a predetermined period of time or determined by at least one of a maximum period of time that a CPU of the server system is capable of operating under a higher current, a discharging time period of the energy storage, or detecting an over-temperature condition.
Some embodiments determine a status of one or more processors of a server system and, in response to detecting that the one or more processors enter a boost mode or consume power exceeding a threshold power value, generate a processor hot signal. In some embodiments, a processor hot signal is generated only when the one or more processors consume power exceeding the threshold power value over a predetermined period of time. The processor hot signal can cause additional cooling to be applied to at least one of the one or more processors, memory, or other components of the server system. In some implementations, additional cooling may include supply more power to cooling components, such as cooling fans, or liquid cooling pumps.
In some embodiments, the processor hot signal can activate a CPU thermal control circuit that is configured to protect processors and other circuit components of the server system against excessive temperatures. In some implementations, the thermal control circuit can cause power to the processor or other components of the server system to be reduced or completely removed in response to detecting an excessive temperature or a temperature exceeding a high threshold temperature, respectively.

DETAILED DESCRIPTION
Various embodiments of the present technology provide systems and methods for providing additional power supplies in a server system by using a energy storage. The energy storage can be charged by increasing a voltage differential of the energy storage by using a boost component in the server system. In some embodiments, a status of one or more processors of a server system can be monitored. In response to detecting that the one or more processors demand a burst of power supply exceeding a threshold high value provided by a power supply unit (PSU) of the server system, a boost activation signal can be generated. The boost activation signal can cause a voltage differential over a energy storage to be reduced from a first voltage to a second voltage, which allows the energy storage to supply stored electrical energy to other components of the server system.
FIG. 1A illustrates a schematic block diagram of an exemplary server system 100 containing a boost component and energy storage in accordance with an implementation of the present technology. In this example, the server system 100 comprises at least one microprocessor or CPU 110 connected to a cache 111, one or more cooling components 112, a main memory 180, at least one power supply unit (PSU) 120 that receives an AC power supply 120 and provides power to the server system 100, a boost component 122, a CPU VR 123, and an energy storage 124 (e.g., a buffer capacitor). The CPU VR 123 is configured to regulate an output voltage of the boost component 122 to supply power to components (e.g., the CPU 110) of the server system 100.
The boost component 122 is configured to boost an output voltage of the PSU 120 to a higher voltage (e.g., from 12V to 48V). The energy storage 124 is capable of storing a comparatively large amount of electrical energy at a relatively low voltage (e.g., 48V) or low current. The amount of electrical energy stored in the energy storage 124 can support additional power demands from components of the server system 100 during a boost mode over a predetermined period of time.
The at least one PSU 120 is configured to supply powers to various component of the server system 100, such as the CPU 110, cache 111, NB logic 130, PCIe slots 160, Memory 180, SB logic 140, ISA slots 150, PCI slots 170, UPS 121 and controller 151. After being powered on, the server system 100 is configured to load software application from memory, computer storage device, or an external storage device to perform various operations.
The main memory 180 can be coupled to the CPU 110 via a north bridge (NB) logic 130. A memory control module (not shown) can be used to control operations of the memory 180 by asserting necessary control signals during memory operations. The main memory 180 may include, but is not limited to, dynamic random access memory (DRAM), double data rate DRAM (DDR DRAM), static RAM (SRAM), or other types of suitable memory.
In some implementations, the CPU 110 can be multi-core processors, each of which is coupled together through a CPU bus connected to the NB logic 130. In some implementations, the NB logic 130 can be integrated into the CPU 110. The NB logic 130 can also be connected to a plurality of peripheral component interconnect express (PCIe) ports 160 and a south bridge (SB) logic 140. The plurality of PCIe ports 160 can be used for connections and buses such as PCI Express x1, USB 2.0, SMBus, SIM card, future extension for another PCIe lane, 1.5 V and 3.3 V power, and wires to diagnostics LEDs on the server's chassis.
In this example, the NB logic 130 and the SB logic 140 are connected by a peripheral component interconnect (PCI) Bus 135. The PCI Bus 135 can support function on the CPU 110 but in a standardized format that is independent of any of CPU's native buses. The PCI Bus 135 can be further connected to a plurality of PCI slots 170 (e.g., a PCI slot 171). Devices connect to the PCI Bus 135 may appear to a bus controller (not shown) to be connected directly to a CPU bus, assigned addresses in the CPU 110's address space, and synchronized to a single bus clock. PCI cards can be used in the plurality of PCI slots 170 include, but are not limited to, network interface cards (NICs), sound cards, modems, TV tuner cards, disk controllers, video cards, small computer system interface (SCSI) adapters, and personal computer memory card international association (PCMCIA) cards.
The SB logic 140 can couple the PCI bus 135 to a plurality of expansion cards or slots 150 (e.g., an ISA slot 152) via an expansion bus. The expansion bus can be a bus used for communications between the SB logic 140 and peripheral devices, and may include, but is not limited to, an industry standard architecture (ISA) bus, PC/104 bus, low pin count bus, extended ISA (EISA) bus, universal serial bus (USB), integrated drive electronics (IDE) bus, or any other suitable bus that can be used for data communications for peripheral devices.
In the example, the SB logic 140 is further coupled to a controller 151 that is connected to the at least one PSU 120. In some implementations, the controller 151 can be a baseboard management controller (BMC), rack management controller (RMC), a keyboard controller, or any other suitable type of system controller. The controller 151 is configured to control operations of the at least one PSU 120 and/or other applicable operations. In some implementations, the controller 151 is configured to monitor processing demands, and components and/or connection status of the server system 100.
In this example, the controller 151 includes a boost activation module 1511. Some implementations enable the boost activation module 1511 to monitor processing demands of the server system 100 and determine whether a boost mode is needed to support the processing demands. In some embodiments, the boost activation module 1511 can also monitor performance of components in processing pipelines of the server systems 100 to determine whether any component of the processing pipelines is a bottleneck of overall performance of the server system 100. In response to determining a boost mode is needed, a boost activation signal can be generated. The boost activation signal can cause the CPU 110, the bottleneck component, or another component of the server system 100 to operate under a higher clock speed such that a higher processing capacity can be achieved in the server system 100.
Although only certain components are shown within the server system 100 in FIG. 1A, various types of electronic or computing components that are capable of processing or storing data, or receiving or transmitting signals can also be included in server system 100. Further, the electronic or computing components in the server system 100 can be configured to execute various types of application and/or can use various types of operating systems. These operating systems can include, but are not limited to, Android, Berkeley Software Distribution (BSD), iPhone OS (iOS), Linux, OS X, Unix-like Real-time Operating System (e.g., QNX), Microsoft Windows, Window Phone, and IBM z/OS.
Depending on the desired implementation for the server system 100, a variety of networking and messaging protocols can be used, including but not limited to TCP/IP, open systems interconnection (OSI), file transfer protocol (FTP), universal plug and play (UpnP), network file system (NFS), common internet file system (CIFS), AppleTalk etc. As would be appreciated by those skilled in the art, the server system 100 illustrated in FIG. 1A is used for purposes of explanation. Therefore, a network system can be implemented with many variations, as appropriate, yet still provide a configuration of network platform in accordance with various embodiments of the present technology.
In exemplary configuration of FIG. 1A, the server system 100 can also include one or more wireless components operable to communicate with one or more electronic devices within a computing range of the particular wireless channel. The wireless channel can be any appropriate channel used to enable devices to communicate wirelessly, such as Bluetooth, cellular, NFC, or Wi-Fi channels. It should be understood that the device can have one or more conventional wired communications connections, as known in the art. Various other elements and/or combinations are possible as well within the scope of various embodiments.
FIG. 1B demonstrates example waveforms of boosting power supplies of a server system in accordance with implementations of the present technology. In this example, processing components of a server system has a current Iop under a normal operation, as shown in a waveform 131. At time t1, in response to an increased processing demand, the operating current of the processing components starts to ramp up.
At time t2, the operating current of the processing components reaches a threshold high value Ipsu, which is a maximum current that a power supply unit (PSU) of the server system can provide. A determination can be made whether to switch the server system to a boost mode. In response to determining that the boost mode is required to support processing demands of the server system, a boost activation signal can be switched from high to low, as shown in a waveform 132. The boost activation signal can cause the energy storage to discharged and supply stored electrical energy to the processing components (e.g., a CPU) of the server system. In some implementations, the discharged energy storage can cause a voltage differential over an energy storage of the server system to be ramped down from a first voltage to a second voltage, as shown in a waveform 134. The first voltage (e.g., 48V) can be substantial larger than the second voltage (e.g., 12V).
From time t2 to time t3, the operating current of the processing components can ramp up from the threshold high value Ipsu to a maximum operating current Ipmax and stay at the maximum operating current Ipmax for a predetermined period of time (i.e., from time t3 to time t4). The maximum operating current Ipmax includes currents supplied by the PSU of the server system and a capacitor current from the energy storage. At time t3, the capacitor current reaches a maximum discharging current Id, as shown in a waveform 133.
At time t4, the boost activation signal can be switched from low to high, which causes the energy storage starts to be charged by the PSU of the server system. In this example, the energy storage is charged by a capacitor current Ic provided the PSU of the server system, the operating current of the processing components drops to a current Icharging at time t4, and the voltage differential over the energy storage of the server system ramps up from the second voltage to the first voltage.
At time t5, the energy storage is fully charged, which causes the capacitor current to be reduced to a low current under a normal operation I0 and causes the operating current of the processing components to be reduced to a current under the normal operation Iop.
One of ordinary skilled in the art will appreciate that waveform diagrams in FIG. 1B are for illustration purpose only. It may take a period of time for a signal to change from high to low or from low to high (e.g., a certain delay for the boost activation signal to change from high to low or low to time). And there may be delay for one signal to react to changes in another signal. For example, there may be a delay for the voltage differential over the energy storage of the server system to ramp down from the first voltage in response to the boost activation signal dropping from high to low.
The above discussion is meant to be illustrative of the principles and various embodiments of the present technology. Numerous variations and modifications will become apparent once the above disclosure is fully appreciated.
FIG. 2 illustrates an exemplary method of boosting power supplies of a server system in accordance with an implementation of the present technology. It should be understood that the exemplary method 200 is presented solely for illustrative purposes and that in other methods in accordance with the present technology can include additional, fewer, or alternative steps performed in similar or alternative orders, or in parallel.
The exemplary method 200 starts with boosting an output voltage of a power supply unit (PSU) of a computing system to a higher voltage, at step 210. The PSU is configured to supply powers to various component of the computing system and/or to charge an energy storage (e.g., a buffer capacitor) of the computing system. In some implementations, the output voltage of the PSU is boosted by a boost component that is connected to the PSU.
At step 220, the energy storage can be charged under the increased DC voltage. In some implementations, the energy storage is connected to an output terminal of the boost component, as illustrated in FIG. 1A. Some embodiments monitor processing demands of the computing system, status of components and/or connection status of the computing system. A determination can be made whether a boost mode is required to support processing demands of the computing system, at step 230.
In response to determining that a boost mode is required to support the processing demands of the computing system, the energy storage can be caused to be discharged during a period of the boost mode, at step 240. In some embodiments, in response to determining that a boost mode is needed, an energy storage can supply stored electrical energy to other components of the computing system. In some implementations, supplying stored electrical energy can cause a voltage differential over the energy storage to be reduced from a first voltage to a second voltage.
In some embodiments, in response to determining that a boost mode is needed or detecting a component being a bottleneck in processing pipelines of the computing system, a boost activation signal can be generated. The boost activation signal can cause a CPU, the bottleneck component, or another component of the computing system to operate under a higher clock speed such that a higher processing capacity can be achieved.
At step 250, the boost mode ends. The energy storage can be charged by the PSU of the computing system. The voltage differential over the energy storage can be ramped up to the first voltage.
TERMINOLOGIES
A computer network is a geographically distributed collection of nodes interconnected by communication links and segments for transporting data between endpoints, such as personal computers and workstations. Many types of networks are available, with the types ranging from local area networks (LANs) and wide area networks (WANs) to overlay and software-defined networks, such as virtual extensible local area networks (VXLANs).
LANs typically connect nodes over dedicated private communications links located in the same general physical location, such as a building or campus. WANs, on the other hand, typically connect geographically dispersed nodes over long-distance communications links, such as common carrier telephone lines, optical lightpaths, synchronous optical networks (SONET), or synchronous digital hierarchy (SDH) links. LANs and WANs can include layer 2 (L2) and/or layer 3 (L3) networks and devices.
The Internet is an example of a WAN that connects disparate networks throughout the world, providing global communication between nodes on various networks. The nodes typically communicate over the network by exchanging discrete frames or packets of data according to predefined protocols, such as the Transmission Control Protocol/Internet Protocol (TCP/IP). In this context, a protocol can refer to a set of rules defining how the nodes interact with each other. Computer networks can be further interconnected by an intermediate network node, such as a router, to extend the effective “size” of each network.
Overlay networks generally allow virtual networks to be created and layered over a physical network infrastructure. Overlay network protocols, such as Virtual Extensible LAN (VXLAN), Network Virtualization using Generic Routing Encapsulation (NVGRE), Network Virtualization Overlays (NVO3), and Stateless Transport Tunneling (STT), provide a traffic encapsulation scheme which allows network traffic to be carried across L2 and L3 networks over a logical tunnel. Such logical tunnels can be originated and terminated through virtual tunnel end points (VTEPs).
Moreover, overlay networks can include virtual segments, such as VXLAN segments in a VXLAN overlay network, which can include virtual L2 and/or L3 overlay networks over which VMs communicate. The virtual segments can be identified through a virtual network identifier (VNI), such as a VXLAN network identifier, which can specifically identify an associated virtual segment or domain.
Network virtualization allows hardware and software resources to be combined in a virtual network. For example, network virtualization can allow multiple numbers of VMs to be attached to the physical network via respective virtual LANs (VLANs). The VMs can be grouped according to their respective VLAN, and can communicate with other VMs as well as other devices on the internal or external network.
Network segments, such as physical or virtual segments, networks, devices, ports, physical or logical links, and/or traffic in general can be grouped into a bridge or flood domain. A bridge domain or flood domain can represent a broadcast domain, such as an L2 broadcast domain. A bridge domain or flood domain can include a single subnet, but can also include multiple subnets. Moreover, a bridge domain can be associated with a bridge domain interface on a network device, such as a switch. A bridge domain interface can be a logical interface which supports traffic between an L2 bridged network and an L3 routed network. In addition, a bridge domain interface can support internet protocol (IP) termination, VPN termination, address resolution handling, MAC addressing, etc. Both bridge domains and bridge domain interfaces can be identified by a same index or identifier.
Furthermore, endpoint groups (EPGs) can be used in a network for mapping applications to the network. In particular, EPGs can use a grouping of application endpoints in a network to apply connectivity and policy to the group of applications. EPGs can act as a container for buckets or collections of applications, or application components, and tiers for implementing forwarding and policy logic. EPGs also allow separation of network policy, security, and forwarding from addressing by instead using logical application boundaries.
Cloud computing can also be provided in one or more networks to provide computing services using shared resources. Cloud computing can generally include Internet-based computing in which computing resources are dynamically provisioned and allocated to client or user computers or other devices on-demand, from a collection of resources available via the network (e.g., “the cloud”). Cloud computing resources, for example, can include any type of resource, such as computing, storage, and network devices, virtual machines (VMs), etc. For instance, resources can include service devices (firewalls, deep packet inspectors, traffic monitors, load balancers, etc.), compute/processing devices (servers, CPU's, memory, brute force processing capability), storage devices (e.g., network attached storages, storage area network devices), etc. In addition, such resources can be used to support virtual networks, virtual machines (VM), databases, applications (Apps), etc.
Cloud computing resources can include a “private cloud,” a “public cloud,” and/or a “hybrid cloud.” A “hybrid cloud” can be a cloud infrastructure composed of two or more clouds that inter-operate or federate through technology. In essence, a hybrid cloud is an interaction between private and public clouds where a private cloud joins a public cloud and utilizes public cloud resources in a secure and scalable manner. Cloud computing resources can also be provisioned via virtual networks in an overlay network, such as a VXLAN.
In a network switch system, a lookup database can be maintained to keep track of routes between a number of end points attached to the switch system. However, end points can have various configurations and are associated with numerous tenants. These end-points can have various types of identifiers, e.g., IPv4, IPv6, or Layer-2. The lookup database has to be configured in different modes to handle different types of end-point identifiers. Some capacity of the lookup database is carved out to deal with different address types of incoming packets. Further, the lookup database on the network switch system is typically limited by 1K virtual routing and forwarding (VRFs). Therefore, an improved lookup algorithm is desired to handle various types of end-point identifiers. The disclosed technology addresses the need in the art for address lookups in a telecommunications network. Disclosed are systems, methods, and computer-readable storage media for unifying various types of end-point identifiers by mapping end-point identifiers to a uniform space and allowing different forms of lookups to be uniformly handled. A brief introductory description of example systems and networks, as illustrated in FIGS. 3 and 4, is disclosed herein. These variations shall be described herein as the various examples are set forth. The technology now turns to FIG. 3.
FIG. 3 illustrates an example computing device 300 suitable for implementing the present technology. Computing device 300 includes a master central processing unit (CPU) 362, interfaces 368, and a bus 315 (e.g., a PCI bus). When acting under the control of appropriate software or firmware, the CPU 362 is responsible for executing packet management, error detection, and/or routing functions, such as miscabling detection functions, for example. The CPU 362 preferably accomplishes all these functions under the control of software including an operating system and any appropriate applications software. CPU 362 can include one or more processors 363 such as a processor from the Motorola family of microprocessors or the MIPS family of microprocessors. In an alternative embodiment, processor 363 is specially designed hardware for controlling the operations of the computing device 300. In a specific embodiment, a memory 361 (such as non-volatile RAM and/or ROM) also forms part of CPU 362. However, there are many different ways in which memory could be coupled to the system.
The interfaces 368 are typically provided as interface cards (sometimes referred to as “line cards”). Generally, they control the sending and receiving of data packets over the network and sometimes support other peripherals used with the computing device 300. Among the interfaces that can be provided are Ethernet interfaces, frame relay interfaces, cable interfaces, DSL interfaces, token ring interfaces, and the like. In addition, various very high-speed interfaces can be provided such as fast token ring interfaces, wireless interfaces, Ethernet interfaces, Gigabit Ethernet interfaces, ATM interfaces, HSSI interfaces, POS interfaces, FDDI interfaces and the like. Generally, these interfaces can include ports appropriate for communication with the appropriate media. In some cases, they can also include an independent processor and, in some instances, volatile RAM. The independent processors can control such communications intensive tasks as packet switching, media control and management. By providing separate processors for the communications intensive tasks, these interfaces allow the master microprocessor 362 to efficiently perform routing computations, network diagnostics, security functions, etc.
Although the system shown in FIG. 3 is one specific computing device of the present technology, it is by no means the only network device architecture on which the present invention can be implemented. For example, an architecture having a single processor that handles communications as well as routing computations, etc. is often used. Further, other types of interfaces and media could also be used with the router.
Regardless of the network device's configuration, it can employ one or more memories or memory modules (including memory 361) configured to store program instructions for the general-purpose network operations and mechanisms for roaming, route optimization and routing functions described herein. The program instructions can control the operation of an operating system and/or one or more applications, for example. The memory or memories can also be configured to store tables such as mobility binding, registration, and association tables, etc.
FIG. 4A, and FIG. 4B illustrate example possible systems in accordance with various aspects of the present technology. The more appropriate embodiment will be apparent to those of ordinary skill in the art when practicing the present technology. Persons of ordinary skill in the art will also readily appreciate that other system examples are possible.
FIG. 4A illustrates a conventional system bus computing system architecture 400 wherein the components of the system are in electrical communication with each other using a bus 405. Example system 400 includes a processing unit (CPU or processor) 410 and a system bus 405 that couples various system components including the system memory 415, such as read only memory (ROM) 420 and random access memory (RAM) 425, to the processor 410. The system 400 can include a cache of high-speed memory connected directly with, in close proximity to, or integrated as part of the processor 410. The system 400 can copy data from the memory 415 and/or the storage device 430 to the cache 412 for quick access by the processor 410. In this way, the cache can provide a performance boost that avoids processor 410 delays while waiting for data. These and other modules can control or be configured to control the processor 410 to perform various actions. Other system memory 415 can be available for use as well. The memory 415 can include multiple different types of memory with different performance characteristics. The processor 410 can include any general purpose processor and a hardware module or software module, such as module 432, module 434, and module 436 stored in storage device 430, configured to control the processor 410 as well as a special-purpose processor where software instructions are incorporated into the actual processor design. The processor 410 can essentially be a completely self-contained computing system, containing multiple cores or processors, a bus, memory controller, cache, etc. A multi-core processor can be symmetric or asymmetric.
To enable user interaction with the computing device 400, an input device 445 can represent any number of input mechanisms, such as a microphone for speech, a touch-sensitive screen for gesture or graphical input, keyboard, mouse, motion input, speech and so forth. An output device 435 can also be one or more of a number of output mechanisms known to those of skill in the art. In some instances, multimodal systems can enable a user to provide multiple types of input to communicate with the computing device 400. The communications interface 440 can generally govern and manage the user input and system output. There is no restriction on operating on any particular hardware arrangement and therefore the basic features here can easily be substituted for improved hardware or firmware arrangements as they are developed.
Storage device 430 is a non-volatile memory and can be a hard disk or other types of computer readable media which can store data that are accessible by a computer, such as magnetic cassettes, flash memory cards, solid state memory devices, digital versatile disks, cartridges, random access memories (RAMs) 425, read only memory (ROM) 420, and hybrids thereof.
The storage device 430 can include software modules 432, 434, 436 for controlling the processor 410. Other hardware or software modules are contemplated. The storage device 430 can be connected to the system bus 405. In one aspect, a hardware module that performs a particular function can include the software component stored in a computer-readable medium in connection with the necessary hardware components, such as the processor 410, bus 405, output device 435 (e.g., a display), and so forth, to carry out the function.
FIG. 4B illustrates a computer system 450 having a chipset architecture that can be used in executing the described method and generating and displaying a graphical user interface (GUI). Computer system 450 is an example of computer hardware, software, and firmware that can be used to implement the disclosed technology. System 450 can include a processor 455, representative of any number of physically and/or logically distinct resources capable of executing software, firmware, and hardware configured to perform identified computations. Processor 455 can communicate with a chipset 460 that can control input to and output from processor 455. In this example, chipset 460 outputs information to output 465, such as a display, and can read and write information to storage device 470, which can include magnetic media, and solid state media, for example. Chipset 460 can also read data from and write data to RAM 475. A bridge 480 for interfacing with a variety of user interface components 485 can be provided for interfacing with chipset 460. Such user interface components 485 can include a keyboard, a microphone, touch detection and processing circuitry, a pointing device, such as a mouse, and so on. In general, inputs to system 450 can come from any of a variety of sources, machine generated and/or human generated.
Chipset 460 can also interface with one or more communication interfaces 590 that can have different physical interfaces. Such communication interfaces can include interfaces for wired and wireless local area networks, for broadband wireless networks, as well as personal area networks. Some applications of the methods for generating, displaying, and using the GUI disclosed herein can include receiving ordered datasets over the physical interface or be generated by the machine itself by processor 455 analyzing data stored in storage 470 or RAM 475.
