Evaluating ARM HPC clusters for scientific workloads

Field: Computer Science (Physical Sciences)

Summary The power consumption of modern high‐performance computing (HPC) systems that are built using power hungry commodity servers is one of the major hurdles for achieving Exascale computation. Several efforts have been made by the HPC community to encourage the use of low‐powered system‐on‐chip (SoC) embedded processors in large‐scale HPC systems. These initiatives have successfully demonstrated the use of ARM SoCs in HPC systems, but there is still a need to analyze the viability of these systems for HPC platforms before a case can be made for Exascale computation. The major shortcomings of current ARM‐HPC evaluations include a lack of detailed insights about performance levels on distributed multicore systems and performance levels for benchmarking in large‐scale applications running on HPC. In this paper, we present a comprehensive evaluation of results that covers major aspects of server and HPC benchmarking for ARM‐based SoCs. For the experiments, we built an unconventional cluster of ARM Cortex‐A9s that is referred to as Weiser and ran single‐node benchmarks (STREAM, Sysbench, and PARSEC) and multi‐node scientific benchmarks (High‐performance Linpack (HPL), NASA Advanced Supercomputing (NAS) Parallel Benchmark, and Gadget‐2) in order to provide a baseline for performance limitations of the system. Based on the experimental results, we claim that the performance of ARM SoCs depends heavily on the memory bandwidth, network latency, application class, workload type, and support for compiler optimizations. During server‐based benchmarking, we observed that when performing memory intensive benchmarks for database transactions, x86 performed 12% better for multithreaded query processing. However, ARM performed four times better for performance to power ratios for a single core and 2.6 times better on four cores. We noticed that emulated double precision floating point in Java resulted in three to four times slower performance as compared with the performance in C for CPU‐bound benchmarks. Even though Intel x86 performed slightly better in computation‐oriented applications, ARM showed better scalability in I/O bound applications for shared memory benchmarks. We incorporated the support for ARM in the MPJ‐Express runtime and performed comparative analysis of two widely used message passing libraries. We obtained similar results for network bandwidth, large‐scale application scaling, floating‐point performance, and energy‐efficiency for clusters in message passing evaluations (NBP and Gadget 2 with MPJ‐Express and MPICH). Our findings can be used to evaluate the energy efficiency of ARM‐based clusters for server workloads and scientific workloads and to provide a guideline for building energy‐efficient HPC clusters.

Metodological problems of comparative researches in education

Field: Social Sciences (Social Sciences)

Each scientific explanation, as per the author's view, is strived and required to have the most possible systematic character, and to enable the explained problem to be comprehended in the widest theoric-systhematic frame. Having analysed the methodological problem of comparative studies in education from the point of view of the mentioned studies, the author determined that the approaches to comparative study of education and schooling were not to be uniformed ones from the simple reason they had been grown out from different philosophic and theoric fundament. From the wider point of view, comparisons enable the comprehension of the phenomenon of education and schooling, their dialectics of manifestation, and their importance for human and society development. Methodologically taken, comparativistics of education and schooling is enriched with new techniques and methods. The comparison overcomes the meaning of one method (comparative method). Different orientations and different methodological procedures in comparative study of education and schooling were being appeared. Bearing in mind the complexity of comparative pedagogy problems, the author indicated the relevant methodological problems from which the historic dimension of comparative pedagogy progress was being visible. The author made the analysis of methodological problem of comparative research in education through several phases having considered basic characteristic of research, understanding of method system of comparative pedagogy, problems of contradiction of comparative research, its presence etc. From the point of view of the indicated problem, it is essential to state the consciousness on the methodological foundation of comparative researches of education and schooling is being broadened, which leads to the research of phenomenon of education at more qualitative level.
Cell Capacitor Voltage Switching-Cycle Balancing Control for Modular Multilevel Converters

Field: Engineering (Physical Sciences)

Modular multilevel converters (MMC) with the conventional control are subjected to large capacitor voltage ripples, especially at low-line frequencies. The existing attenuation approaches, such as the second-order or high-frequency harmonic injections, are designed based on average models limiting the achievable performance. This letter aims to greatly increase the control time resolution, investigating the possibility to form the control in the timescale of a switching cycle. The circulating current is allowed to have multiple changes in one switching period. This critical alternation equips the MMC with the capability to achieve voltage balancing in a single switching cycle, shifting the MMC from a long-deemed “line-cycle balancing” converter to a “switching-cycle balancing” converter. The proposed approach is experimentally verified under dc–dc operation, which is the most challenging scenario for conventional controls. Test results under 6 kV dc-link voltage are provided performed with the custom-built 10-kV SiC mosfet -based MMC prototype.
Strongly interacting Fermi gases

Field: Physics and Astronomy (Physical Sciences)

Strongly interacting gases of ultracold fermions have become an amazingly rich test-bed for many-body theories of fermionic matter. Here we present our recent experiments on these systems. Firstly, we discuss high-precision measurements on the thermodynamics of a strongly interacting Fermi gas across the superfluid transition. The onset of superfluidity is directly observed in the compressibility, the chemical potential, the entropy, and the heat capacity. Our measurements provide benchmarks for current many-body theories on strongly interacting fermions. Secondly, we have studied the evolution of fermion pairing from three to two dimensions in these gases, relating to the physics of layered superconductors. In the presence of p-wave interactions, Fermi gases are predicted to display toplogical superfluidity carrying Majorana edge states. Two possible avenues in this direction are discussed, our creation and direct observation of spin-orbit coupling in Fermi gases and the creation of fermionic molecules of 23Na 40K that will feature strong dipolar interactions in their absolute ground state.

Unfolding the Future: Bifurcation in Organizing Form and Emergence in Social Systems

Field: Social Sciences (Social Sciences)

This paper presents a complexity science informed theory to describe how organizing forms emerge and foster innovation. The theory explores the bidirectional linkages between fine-grained interactions among human beings in a complex adaptive system and the emergent coarse-grained properties that characterize qualitatively distinct and yet stable organizing forms in social systems. By exploiting a mathematical foundation that has been successfully employed in analogous cases in the natural sciences, it opens the door to a rigorous theory of performance and adaptation in human systems by relating changing local rules of interaction to qualitative changes in emerging organizing forms. This process is mediated by evolving models of the system in the environment developed and shared among individuals. Finally, the paper explores whether this model can be used canonically and does so in the context of axiomatic hurdles that must be overcome if a practical mathematical theory of human organizing is to be realized.
Average CT in PET studies of colorectal cancer patients with metastasis in the liver and esophageal cancer patients

Field: Medicine (Health Sciences)

Average CT (ACT) and PET have a similar temporal resolution and it has been shown to improve registration of the CT and PET data for PET/CT imaging of the thorax. The purpose of this study was to quantify the effect of ACT attenuation correction on PET for gross tumor volume (GTV) delineation with standardized uptake value (SUV) for liver and esophageal lesions. Our study included 48 colorectal cancer patients with metastasis in the liver and 52 esophageal cancer patients. These patients underwent a routine PET/CT scan followed by a cine CT scan of the thoracic region for ACT. Differences between the two PET data sets ( and ) corrected with the helical CT (HCT) and ACT were quantified by analyzing image alignment, maximum SUV , and GTV. The 67% of the colorectal and 73% of the esophageal studies demonstrated misregistration between the and HCT data. ACT was effective in removing misregistration artifacts in 65% of the misregisted colorectal and in 76% of the misregisted esophageal cancer patients. Misregistration between the CT and PET data affected GTVs due to the change in with ACT. A change of greater than 20% between and was found in 15% of the colorectal and 17% of the esophageal cases. Our results demonstrated a more pronounced effect of misregistration for the smaller lesions near the diaphragm . ACT was effective in improving registration between the CT and PET data in PET/CT for the colorectal and esophageal cancer patients. PACS number: 87.58.Fg
Design of a liver cancer‑specific selector for the analysis of circulating tumor DNA

Field: Medicine (Health Sciences)

Circulating tumor DNA (ctDNA) has been frequently investigated to monitor tumor dynamics and measure tumor burden. This non-invasive method concerning ctDNA has been recognized as a promising biomarker. Recently, next generation sequencing has been used in ctDNA detection by researchers. However, those reports have been limited by modest sensitivity, and only a minority of patients with cancer were applicable. Additionally, a limited number of cases of liver cancer have been analyzed. A more precise method is required to be established to evaluate ctDNA noninvasively. In the present study, a novel method to design a liver cancer-associated chip region (spanning 211 kb, containing 159 genes) was performed with high specificity using International Cancer Genome Consortium datasets. Following evaluation with datasets from The Cancer Genome Atlas and data from 3 patients with liver cancer, the selected regions were demonstrated to be beneficial to locate specific somatic mutations associated with liver cancer therapy and to monitor cancer dynamics in the plasma samples of the patients. In addition to establishing performance benchmarks supporting direct clinical use, the chip designed and the high-resolution sequencing analyses pipeline would allow the development a set of patient specific markers that could monitor the process of cancer with high accuracy and low cost. Furthermore, the present study is essential to understanding the dynamics and providing insight into the basic mechanisms of liver cancer.

Density of states of a coupled-channel system

Field: Physics and Astronomy (Physical Sciences)

We demonstrate how an effective density of states can be derived from the S-matrix describing a coupled-channel system. Besides the locations of poles, the phase of the determinant of the S-matrix encodes essential details in characterizing the dynamics of resonant and non-resonant interactions. The density of states is computed for the two channel scattering problem ($\pi\pi, K \bar{K}$, S-wave), and the influences from the various dynamical structures: poles, roots, branch cuts, and Riemann sheets, are examined.

Comparison of Safety and Efficiency between Tiger-2 Catheter with Right Radial Artery Access and Judkins Catheter with Left Radial Artery Access

Field: Medicine (Health Sciences)

We sought to compare the safety and efficiency of Tiger-2 in the right radial and Judkins catheter in the left radial access. We retrospectively collected data of 487 patients, involving 172 patients after coronary angiography with Judkins on the left radial artery and 315 patients with Tiger-2 on the right radial artery access. There were no differences in baseline characteristics, except for hypertension ratio and mean age. There was a difference in pulse absence on the radial artery. The volume of contrast used was higher in the Judkins group. Both groups differed in the amount of drugs administered (NTG and heparin). Fluorescence times were comparable between groups. Radiation dosage and AK was significantly greater in the Tiger-2 group. The Tiger-2 catheters were significantly more often changed to another type of catheter (100 changes) than the Judkins (12 changes). However, there was no statistical difference in access site change. Judkins with left radial access seems to be a safer option because of the lower radiation exposure and less incidence of complications than Tiger-2 with right radial access, however, it requires a higher volume of contrast.
The response of Plantago major ssp. pleiosperma to elevated CO2 is modulated by the formation of secondary shoots

Field: Agricultural and Biological Sciences (Life Sciences)

summary The effect of elevated CO 2 on the relative growth rate (RGR) of Plantago major ssp. pleiosperma was studied during the vegetative stage, in relation to plant development, by growing plants at 350 μl 1 −1 or at 700 μl 1 −1 CO 2 in non‐limiting nutrient solution with nitrate. To minimize interference by the accumulation of non‐structural carbohydrates in the interpretation of results, RGR was expressed on a f. wt basis (RGR FW ), as were all plant weight ratios. Stimulation of the RGR FW of the whole plant by elevated CO 2 was transient, and did not last longer than 8 d. At the same time a transient increase in root weight ratio (RWR) was observed. In order to investigate whether the transient effect of elevated CO 2 on rgr fw was size‐dependent, the data were plotted versus total f. wt (log e , transformed). The transient period of stimulation of rgr fw and of rwr by elevated CO 2 was still found, but in both CO 2 treatments rgr fw decreased after a certain plant size had been reached. This size coincided with the stage at which secondary shoots started to develop, and was reached earlier in plants grown at elevated CO 2 . The rgr of these secondary shoots ( rgr set .) was still increased when the period of whole plant stimulation of rgr fw had ended, indicating that the development of these new sinks took priority over a continuation of the stimulation of rwr . It is hypothesized that in this Plantago subspecies the response of the rgr fw of the whole plants to elevated CO 2 is modulated by the formation of secondary shoots. Apparently, partitioning of the extra soluble carbohydrates at elevated CO 2 to this tissue takes precedence over partitioning to the roots, resulting in a cessation of stimulation of plant rgr fw by elevated CO 2 .
Investigation of the Effects of Xenoestrogens on the Protein Levels of the Estrogen Receptors

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

There has been an increase in reports of male reproductive disorders that include male infertility and testicular cancer worldwide. It has been suggested that agents such as xenoestrogens could be responsible. Xenoestrogens are chemical compounds that mimic the action of estrogens by binding to the estrogen receptors (ERs). The response ofa testicular cell line to estrogenic pesticides was examined. The effect of estrogenic pesticides on the growth and protein levels of ERα and ERβ of mouse Sertoli cells was investigated. Pyrethroids are widely used insecticides due to their insecticidal potency and low mammalian toxicity. In this study, the estrogenicity ofpyrethroid chemicals were tested using the yeast estrogen screen (YES) assay. The toxic effects of the pyrethroid compounds cypermethrin, 3-(4-hydroxy-phenoxy)benzyl alcohol (metabolite of permethrin), and the commercial product (Ripcord Plus) were evaluated. The Sertoli cells were exposed to pyrethroids at concentrations of 0.36 nM and 36 µM (cypermethrin and Ripcord Plus), and 0.69 nM and 69 µM (metabolite) for 100 h. The expression of the ERs was analysed through the use of Enzyme Linked ImmunoSorbent Assay (ELISA) experiments. The most toxic pyrethroid was the metabolite, followed by Ripcord Plus then cypermethrin. Overall the exposure of the cells to cypermethrin (36 µM), Ripcord Plus (36 µM) and the metabolite (69 µM) caused a significant decrease (p<0.05) in ERα levels. In the cultures exposed to the metabolite (69 µM), there was also a significant increase in ERβ levels. There appears to be a relation between cell toxicity and an increase in ERβ levels, which supports the theory that ERβ promotes apoptosis. Pyrethroids are rapidly excreted from the body, and it is unknown if there is accumulation in the male testes. Male fertility could be affected through molecular mechanisms involving the ERs, should cells in the male testes be exposed to these pyrethroids at physiologically relevant concentrations.
Effect of Channel Side Information on the Capacity of MIMO Systems in Correlated Fading Channels

Field: Engineering (Physical Sciences)

Abstract — Using antenna arrays at both sides of the wireless communication link (MIMO systems) can result in high channel capacity provided that the channel is ideal, i.e., propagation medium is rich scattering or Rayleigh fading, the antenna arrays at both sides are uncorrelated. Also, the availability of channel side information (CSI) at the transmitter further enhances the capacity of ideal channels. This paper investigates the effect of CSI availability at the transmitter on the capacity of correlated MIMO channels under Rician fading. It is concluded that the availability of CSI at the transmitter is more significant at low SNR, and the improvement in capacity when CSI is available at the transmitter is more pronounced at higher values of the Rician parameter K and correlation parameter r.
