Question: What technology company created the Group Control System operating system and is located in Armonk, New York?

full_context: Document 1: OS/360 and successors: OS/360, officially known as IBM System/360 Operating System, is a discontinued batch processing operating system developed by IBM for their then-new System/360 mainframe computer, announced in 1964; it was heavily influenced by the earlier IBSYS/IBJOB and Input/Output Control System (IOCS) packages. It was one of the earliest operating systems to require the computer hardware to include at least one direct access storage device.
Document 2: Advanced Comprehensive Operating System: Advanced Comprehensive Operating System is a family of mainframe computer operating systems developed by NEC for the Japanese market. It consists of three systems, based on the General Comprehensive Operating System family developed by General Electric, Honeywell, and Bull. Two of these systems, ACOS-2 (based on GCOS 4) and ACOS-4 (based on GCOS 7) are still sold, although only ACOS-4 is under active development. ACOS-6 (based on GCOS 8) is an obsolete high-end mainframe platform, which ceased active development in the early 2000s.
Document 3: Apple GS/OS: GS/OS is an operating system developed by Apple Computer for its Apple IIGS personal computer that uses the ProDOS filing system. It provides facilities for accessing the file system, controlling input/output devices, loading and running program files, and a system allowing programs to handle interrupts and signals. GS/OS was included as a component of Apple II System Software versions 4.0 through 6.0.1. GS/OS, unlike its predecessor, is written entirely in 16-bit code and was the first true 16-bit operating system for the Apple IIGS.
Document 4: IBM jStart: Founded in 1997, IBM's jStart team is IBM's primary client engagement group for emerging internet technologies. The team is part of IBM Software Solutions Group, and is a component of the Emerging Technologies team. jStart is responsible for creating prototypes and solutions for companies around the world, and has frequently launched the first implementations of technologies for introduction into the enterprise.

Document 7: OSv: OSv (stylized OS) is a cloud computing focused computer operating system released on September 16, 2013. It is a special-purpose operating system built to run as a guest on top of a virtual machine, thus it does not include drivers for bare-metal hardware. It is a unikernel, designed to run a single Linux executable or an application written in one of the supported runtime environments (such as Java). For this reason, it does not support a notion of users (it's not a multiuser system) or processes - everything runs in the kernel address space. Using a single address space removes some of the time-consuming operations associated with context switching. It uses large amounts of code from the FreeBSD operating system, in particular the network stack and the ZFS file system. OSv can be managed using a REST Management API and an optional command line interface written in Lua.
Document 8: HCL Technologies: HCL Technologies Limited is an Indian multinational IT services company, headquartered in Noida, Uttar Pradesh, India. It is a subsidiary of HCL Enterprise. Originally a research and development division of HCL, it emerged as an independent company in 1991 when HCL ventured into the software services business. HCL Technologies (the abbreviation of Hindustan Computers Limited) offers services including IT consulting, enterprise transformation, remote infrastructure management, engineering and R&D, and business process outsourcing (BPO). HCL also provides services such as DRYiCE, Cybersecurity and Digital & Analytics.
Document 9: Group Control System: Group Control System (GCS) is an operating system made by IBM, meant to run as a guest of VM. GCS is an integral component of the discontinued VM/SP (since VM/SP 4), VM/XA SP, VM/ESA and current z/VM IBM System product offerings.
Document 10: ILOG: ILOG was an international software company purchased and incorporated into IBM announced in January, 2009. It created enterprise software products for supply chain, business rule management, visualization and optimization. The main product line for Business Rules Management Systems (BRMS) has been rebranded as IBM Operational Decision Manager (ODM).

Document 13: XaAES: FreeMint, MultiTOS, and a few more obscure OSes are all successors to TOS the proprietary operating system of the Atari ST computer. Later models of the ST Computer were called the TT and the Falcon. TOS stands for The Operating System or Tramiel Operating System, as Jack Tramiel was the owner of Atari. GEMDOS itself was a near clone of DOS, the IBM PC OS. This was most visible to users in the 8.3 character file naming system. Like all personal computer operating systems of the day, TOS was single tasking. GEM, the graphical user interface, was licensed from Digital Research and was not included in Apple's lawsuit against DR, thus the Macintosh like appearance and ways of doing things remained on Atari computers. As time went on, the big goal for the ST within and without Atari was to have a multitasking TOS.
Document 14: Cloudscaling: The Cloudscaling Group, Inc., was a software company based in San Francisco, California, USA. The company’s Open Cloud System is a cloud computing system based on the OpenStack open-source software project. It is used to deploy infrastructure as a service (IaaS) public, private and hybrid clouds that support applications typically found on public cloud infrastructures such as Amazon Web Services or Google Compute Engine. These applications are often referred to as cloud-ready applications, which Cloudscaling refers to as dynamic applications and are contrasted with traditional enterprise IT applications.
Document 15: BUNCH: The BUNCH was the nickname for the group of mainframe computer competitors to IBM in the 1970s. The name is derived from the names of the five companies: Burroughs, UNIVAC, NCR, Control Data Corporation (CDC), and Honeywell. These companies were grouped together because the market share of IBM was much higher than all of its competitors put together.
