Compiler-Optimized Simulation of Large-Scale Applications on High Performance Architectures

In this paper, we propose and evaluate practical, automatic techniques that exploit compiler analysis to facilitate simulation of very large message-passing systems. We use compiler techniques and a compiler-synthesized static task graph model to identify the subset of the computations whose values have no significant effect on the performance of the program, and to generate symbolic estimates of the execution times of these computations. For programs with regular computation and communication patterns, this information allows us to avoid executing or simulating large portions of the computational code during the simulation. It also allows us to avoid performing some of the message data transfers, while still simulating the message performance in detail. We have used these techniques to integrate the MPI-Sim parallel simulator at UCLA with the Rice dHPF compiler infrastructure. We evaluate the accuracy and benefits of these techniques for three standard message-passing benchmarks on a wide range of problem and system sizes. The optimized simulator has errors of less than 16% compared with direct program measurement in all the cases we studied, and typically much smaller errors. Furthermore, it requires factors of 5 to 2000 less memory and up to a factor of 10 less time to execute than the original simulator. These dramatic savings allow us to simulate regular message-passing programs on systems and problem sizes 10 to 100 times larger than is possible with the original simulator, or other current state-of-the-art simulators.
Towards a global online reputation

Today's online reputation systems lack one important feature: globality. Users build a reputation within one community, and sometimes several reputations within several communities, but each reputation is only valid within the corresponding community. Moreover, such reputation is usually aggregated by the online platform's provider, giving the inquiring agent no say in the process. This paper proposes one way of dealing with this problem. We introduce an online reputation centralizer that collects raw reputation data about users from several online communities and allows for it to be aggregated according to the inquiring agent's requirements, using a stochastic trust model, and taking into account factors that qualify a user's reputation.
Fault - tolerant design of the IBM POWER6™ microprocessor

The IBM Power6 microprocessor extends the capabilities of the Power5, dramatically increasing its ability to recover from hard and soft errors without increasing system downtime. The Power6 adds new mainframe-like features for enhanced reliability, availability, and serviceability, including instruction retry and processor failover. Optimized for performance and power, the Power6 implements these RAS enhancements without compromising ultrahigh-frequency operation.
Defining the Functional Domain of Programmed Cell Death 10 through Its Interactions with Phosphatidylinositol-3,4,5-Trisphosphate

Cerebral cavernous malformations (CCM) are vascular abnormalities of the central nervous system predisposing blood vessels to leakage, leading to hemorrhagic stroke. Three genes, Krit1 (CCM1), OSM (CCM2), and PDCD10 (CCM3) are involved in CCM development. PDCD10 binds specifically to PtdIns(3,4,5)P3 and OSM. Using threading analysis and multi-template modeling, we constructed a three-dimensional model of PDCD10. PDCD10 appears to be a six-helical-bundle protein formed by two heptad-repeat-hairpin structures (α1–3 and α4–6) sharing the closest 3D homology with the bacterial phosphate transporter, PhoU. We identified a stretch of five lysines forming an amphipathic helix, a potential PtdIns(3,4,5)P3 binding site, in the α5 helix. We generated a recombinant wild-type (WT) and three PDCD10 mutants that have two (Δ2KA), three (Δ3KA), and five (Δ5KA) K to A mutations. Δ2KA and Δ3KA mutants hypothetically lack binding residues to PtdIns(3,4,5)P3 at the beginning and the end of predicted helix, while Δ5KA completely lacks all predicted binding residues. The WT, Δ2KA, and Δ3KA mutants maintain their binding to PtdIns(3,4,5)P3. Only the Δ5KA abolishes binding to PtdIns(3,4,5)P3. Both Δ5KA and WT show similar secondary and tertiary structures; however, Δ5KA does not bind to OSM. When WT and Δ5KA are co-expressed with membrane-bound constitutively-active PI3 kinase (p110-CAAX), the majority of the WT is co-localized with p110-CAAX at the plasma membrane where PtdIns(3,4,5)P3 is presumably abundant. In contrast, the Δ5KA remains in the cytoplasm and is not present in the plasma membrane. Combining computational modeling and biological data, we propose that the CCM protein complex functions in the PI3K signaling pathway through the interaction between PDCD10 and PtdIns(3,4,5)P3.
Fast Bulk Bitwise AND and OR in DRAM

Bitwise operations are an important component of modern day programming, and are used in a variety of applications such as databases. In this work, we propose a new and simple mechanism to implement bulk bitwise AND and OR operations in DRAM, which is faster and more efficient than existing mechanisms. Our mechanism exploits existing DRAM operation to perform a bitwise AND/OR of two DRAM rows completely within DRAM. The key idea is to simultaneously connect three cells to a bitline before the sense-amplification. By controlling the value of one of the cells, the sense amplifier forces the bitline to the bitwise AND or bitwise OR of the values of the other two cells. Our approach can improve the throughput of bulk bitwise AND/OR operations by 9:7X and reduce their energy consumption by 50:5X. Since our approach exploits existing DRAM operation as much as possible, it requires negligible changes to DRAM logic. We evaluate our approach using a real-world implementation of a bit-vector based index for databases. Our mechanism improves the performance of commonly-used range queries by 30 percent on average.
Common Mode Current Suppression in Full-Bridge Converter Based on Simulated Annealing Algorithm

In PWM converter, the serious electromagnetic interference (EMI) is occurred due to high speed operation of switch devices. In this paper, production mechanism of common mode (CM) current in single phase full-bridge converter is analyzed, and severe affection to CM current owing to different transmission delays of two drive pulses is illustrated. It is proposed a digital CM current suppression method based on optimal drive pulses. A novel evaluation measure for CM noise level based on the energy of CM noise current is proposed. The relationship between CM noise level and the delay time of drive signals is studied. Simulated annealing searching algorithm is used to search for the global optimum of CM current energy. Simulated results show that CM current suppression based on simulated annealing algorithm (SAA) can regulate the delay time of drive signals without getting trapped at local minimums. It suppresses CM current level effectively and improves the EMC performance of PWM converter
Global and Convex Optimization in Modeling Environments: Compiler-Based, Excel, and Mathematica Implementations

We present a review of several software products that serve to analyze and solve highly nonlinear—specifically including global—optimization problems across different hardware and software platforms. The implementations discussed are LGO, as a stand-alone, but compiler-dependent modeling and solver environment; its Excel platform implementation; and MathOptimizer, a native solver package for Mathematica users. The discussion advocates the use of hybrid solution strategies, in the context of practical global optimization. Several non-trivial illustrative applications, taken from the literature or received from users of our software products, are also reviewed.
Combined Effects of Ozone and Drought on the Physiology and Membrane Lipids of Two Cowpea (Vigna unguiculata (L.) Walp) Cultivars

The interactive effects of drought and ozone on the physiology and leaf membrane lipid content, composition and metabolism of cowpea (Vigna unguiculata (L.) Walp. ) were investigated in two cultivars (EPACE-1 and IT83-D) grown under controlled conditions. The drought treatment (three-week water deprivation) did not cause leaf injury but restricted growth through stomatal closure. In contrast, the short-term ozone treatment (130 ppb 12 h daily during 14 day) had a limited impact at the whole-plant level but caused leaf injury, hydrogen peroxide accumulation and galactolipid degradation. These effects were stronger in the IT83-D cultivar, which also showed specific ozone responses such as a higher digalactosyl-diacylglycerol (DGDG):monogalactosyl-diacylglycerol (MGDG) ratio and the coordinated up-regulation of DGDG synthase (VuDGD2) and ω-3 fatty acid desaturase 8 (VuFAD8) genes, suggesting that membrane remodeling occurred under ozone stress in the sensitive cultivar. When stresses were combined, ozone did not modify the stomatal response to drought and the observed effects on whole-plant physiology were essentially the same as when drought was applied alone. Conversely, the drought-induced stomatal closure appeared to alleviate ozone effects through the reduction of ozone uptake.
Example-based error recovery strategy for spoken dialog system

Error handling has become an important issue in spoken dialog systems. We describe an example-based approach to detect and repair errors in an example-based dialog modeling framework. Our approach to error recovery is focused on the re-phrase strategy with a system and a task guidance to help the novice users to re-phrase well-recognizable and well-understandable input. The dialog system gives possible utterance templates and contents related to the current situation when errors are detected. An empirical evaluation of the car navigation system shows that our approach is effective to the novice users for operating the spoken dialog system.
Feasibility study of an internally cooled bipolar applicator for RF coagulation of hepatic tissue: Experimental and computational study

Purpose: To study the capacity of an internally cooled radiofrequency (RF) bipolar applicator to create sufficiently deep thermal lesions in hepatic tissue. Materials and methods: Three complementary methodologies were employed to check the electrical and thermal behaviour of the applicator under test. The experimental studies were based on excised bovine (ex vivo study) and porcine liver (in vivo study) and the theoretical models were solved by means of the finite element method (FEM). Results: Experimental and computational results showed good agreement in terms of impedance progress and lesion depth (4 and 4.5 mm respectively for ex vivo conditions, and ≈7 and 9 mm respectively for in vivo conditions), although the lesion widths were overestimated by the computer simulations. This could have been due to the method used to assess the thermal lesions; the experimental lesions were assessed by the white coagulation zone, whereas the tissue damage function was used to assess the computational lesions. Conclusions: The experimental results suggest that this applicator could create in vivo lesions to a depth of around 7 mm. It was also observed that the thermal lesion is mainly confined to the area between both electrodes, which would allow lesion width to be controlled by selecting a specific applicator design. The comparison between the experimental and computational results suggests that the theoretical model could be usefully applied in further studies of the performance of this device.

Integrated matrix converter switch

This paper presents the design, assembly, functional test and preliminary technology assessment of highly integrated power switches for matrix converter application. The design is based on a built-in reliability approach and is verified experimentally by both functional and reliability tests. The assembly is based on a fully bond-wire-less double-sided cooling packaging solution, also featuring device stacking. As compared with standard solutions, the proposed integration approach brings along significant advancements in power density, as well as improvements in electro-magnetic and electro-thermal performance, by relying on a fully bond-wire-less double-sided cooled packaging concept.
A review of laboratory animal anesthesia with chloral hydrate and chloralose.

Chloral hydrate (CH) and alpha-chloralose (CS) are often used to anesthetize laboratory animals although, to our knowledge, there have been no controlled studies of their anesthetic or analgesic effects. Induction of and recovery from anesthesia can be stressful, and anesthesia and analgesic quality have been questioned. Intraperitoneal (i.p.) administration of CH has resulted in adynamic ileus and peritonitis in rats, gastric ulcers in rats, and peritonitis in swine. Light anesthesia is induced in rats. In dogs, CH induces sedation to deep anesthesia when given intravenously. Gastric irritation in dogs can occur when CH is given orally. Chloral hydrate is considered a good sedative-hypnotic for farm animals. Intravenously administered CS anesthetizes dogs and cats for 5 to 10 hours, but the animals may require respiratory support. Chloralose appears to be a satisfactory anesthetic for dogs when stage III thiobarbiturate anesthesia is first induced. It is difficult to gauge the depth of anesthesia and analgesia with CS. In our clinical experience with swine and calves, CH given i.p. leads to adynamic ileus. We have found that CS given i.p. causes an inflammatory response in guinea pigs, rats, and calves. We observed that CS analgesia varies with the type of surgical procedure performed. Based on a literature review and our clinical experience, we suggest that CH or CS anesthesia should be preceded by administration of barbiturates, opioids, alpha-2 agonists, or phenothiazine tranquilizers. Chloral hydrate should only be used as a sedative or hypnotic for dogs; CS should not be used as a sole anesthetic agent. Neither drug should be used i.p. for survival surgery.
Relationship between the Binary Kernels of Visually Evoked Potentials and the Visual Responses on the Magnocellular and Parvocellular Pathways

Summary Objectives : To investigate the nonlinear characteristics of visual evoked potentials (VEPs), and their correlation with the visual responses on parvocellular and magnocellular pathways. First and second-order kernels of the VEPs elicited by several checkerboard patterns were estimated, and their relations to the visual pathway responses were investigated. Methods : VEPs elicited by checkerboard pattern (0.5, 1.0, 2.0 and 4.0 c/d) alternating based on pseudorandom binary sequence were measured, and thei binary kernels were calculated. First and second-order binary kernels were compared with amplitudes o the steady-state VEPs (S-VEPs) to pattern reversal stimulation with a constant temporal frequency (4, 8, 12, 16, and 32 Hz). Results : Positive peak latencies at 150 ms (P150) of second-order first and second slices were correlated with S-VEP amplitude for higher temporal frequencies, indicating that the first and second slices reflect the response of the magnocellular. However, for second and third slices, their amplitudes were partially correlated with 4-16 Hz S-VEP, and this indicated that the second slice contains both magno- and parvocellular pathway responses. P150 latencies of third slices were correlated with S-VEP for lower temporal frequencies, indicating that third slice reflects the response of the parvocellular pathway. Conclusions : The lower slices of second-order binary kernels reflect the response of the magnocellular pathway and the higher slices reflect those on the parvocellular pathway in the human visual system of VEPs.
Leaching of Five Pesticides of Contrasting Mobility through Frozen and Unfrozen Soil

Significantly more pesticides leached from frozen than from unfrozen soil columns. Rapid breakthrough of pesticides indicated preferential flow in frozen soil. A strong negative correlation between Kf and leaching was observed. The effect of sorption properties is weaker in the presence of macropore flow. Macropore flow may be less important for highly mobile or highly sorbed pesticides.
A dual-band UV and IR quantum cascade photodetector

We have proposed a new dual band quantum cascade photodetector with ability of detecting UV and IR through two independent paths. Because of large band gap of GaN and AlGaN, we have used AlxGa1−xN/AlN quantum wells. For detecting of IR and UV intersubband and interband transitions have been used respectively. For IR and UV path we have achieved peak of Responsivity about 60 mA/W at 2.7 um and 25 mA/W at 245 nm at 300K respectively.
Global Distribution of the Oceanic Bottom Mixed Layer Thickness

The ocean bottom is the Earth's least explored region, and the bottom mixed layer (BML) is the pathway for communication between the ocean interior and the ocean floor. In this study, we used full‐depth conductivity‐temperature‐depth profiles archived by the World Ocean Circulation Experiment Program to obtain the first approximation of the global distribution of the oceanic BML thickness, HBML, by applying an integrated method (Huang, Cen, et al., 2018, https://doi.orag/10.1175/jtech-d-18-0016.1). We found that the median HBML values were 40, 42, and 64 m in the Atlantic, Indian, and Pacific Oceans, respectively, and 47 m globally. Statistically, the peak values for the median HBML were around 20°N or 20°S, and it had weak dependence on the buoyancy frequency, where a thin HBML corresponded to strong stratification. In addition, the median HBML became thicker with the ocean depth (D), according to HBML = 26.34 + 0.85e(D/1271.8).
WAFTL: A workload adaptive flash translation layer with data partition

Current FTL schemes have inevitable limitations in terms of memory requirement, performance, garbage collection overhead, and scalability. To overcome these limitations, we propose a workload adaptive flash translation layer referred to as WAFTL. WAFTL explores either page-level or block-level address mapping for normal data block based on access patterns. Page Mapping Block (PMB) is used to store random data and handle large number of partial updates. Block Mapping Block (BMB) is utilized to store sequential data and lower overall mapping table. PMB or BMB is allocated on demand and the number of PMB or BMB eventually depends on workload. An efficient address mapping is designed to reduce overall mapping table and quickly conduct address translation. WAFTL explores a small part of flash space as Buffer Zone to log writes sequentially and migrate data into BMB or PMB based on threshold. Static and dynamic threshold setting are proposed to balance performance and mapping table size. WAFTL has been extensively evaluated under various enterprise workloads. Benchmark results conclusively demonstrate that proposed WAFTL is workload adaptive and achieves up to 80% performance improvement, 83% garbage collection overhead reduction and 50% mapping table reduction compared to existing FTL schemes.
Optimization of Chaetoceros gracilis Microalgae Production for Fish Feeding Using an Airlift Photobioreactor

An experimental procedure was carried out to maximize Chaetoceros gracilis growth. Chaetoceros gracilis , marine microalgae, is considered for feeding fisheries with no GMO (Genetically Modified Organisms) to avoid human health hazards. Furthermore, following United Nations Resolution on water, the microalgae is grown in photobioreactors due to its low water usage. To maximize the microalgae growth, an experimental design was carried out to analyze the effects of Light Intensity, CO 2 supply per day, Sparger type, Photoperiod and Inlet airflow, pH and water temperature were monitored but not controlled. It was found that Light intensity and CO 2 supply per day have statistical significance. Out of three possible scenarios, 1700 lux and 80 gr/day of CO 2 , leads to a cell density at day three of 310×10 4 cel/mL which represents 20% more of the density attained in day two under bag (standard) growing conditions. It was also found that water Ph has also a strong effect over cell density.
Crystallization and X-ray diffraction studies of a complete bacterial fatty-acid synthase type I

Bacterial and fungal type I fatty-acid synthases (FAS I) are evolutionarily connected, as bacterial FAS I is considered to be the ancestor of fungal FAS I. In this work, the production, crystallization and X-ray diffraction data analysis of a bacterial FAS I are reported.
Subword and phonetic search for detecting out-of-vocabulary keywords

We compare several approaches, separately and together, for spotting of out-of-vocabulary (OOV) keywords, in terms of their ATWV scores. We considered three types of recognition units (whole words, syllables, and subwords of different lengths) and two basic search strategies (whole-unit, fuzzy phonetic search). In all cases, the search was performed by collapsing the recognition lattice into a consensus network, either in terms of the recognized whole units, or by ﬁrst splitting the recognized units into phonemes. We ran experiments on ﬁve languages, for which the language model and vocabulary were derived from only 10 hours of transcriptions (70k-100k words of text), resulting in keyword OOV rates varying from 10% to 63% on new data, depending on the language. Our conclusions were that: 1) In all cases, the fuzzy phonetic search on phoneme-split lattices is better than searching for the whole units, 2) The syllable units are the best of the subword units for OOV keyword detection using fuzzy phonetic search, and 3) These methods combine very well, sometimes resulting in ATWV scores for OOV terms which are not too far below those of IV terms.
Patterns of Value Change During the Life Span

Little research has examined mean-level change in values across the life span. Using large cross-sectional data (N = 36,845) from the five geo-social regions in Brazil, this study examines how mean levels of basic values differ as a function of age (from age 12 to 65; M = 28) and whether age effects are moderated by gender. Results show that mean-level value change is substantial throughout the life course. We observed both linear and curvilinear patterns of change as well as differential patterns by gender. The observed value change is consistent with age-related life circumstances and psychosocial development. Age effects are also value dependent, supporting the notion that values have different functions for different developmental stages.
