Abstract This study evaluates the performance and portability of Weather Research Forecasting model in high-performance computing environments, comparing traditional baremetal deployments with containerized executions using Singularity. Experiments were conducted on TeideHPC system, focusing execution time, impact different compilers (Intel vs. GCC), parallelization strategies (MPI OpenMP). The results indicate that while Singularity introduces a overhead 11 to 15%, it offers significant...
Abstract Over the past few years, ARM has been dominant player in embedded systems and System-on-Chips (SoCs). With emergence of hardware platforms based on RISC-V architecture, a practical comparison focusing their energy efficiency performance is needed. In this study, our goal to comprehensively evaluate SoCs three different systems. We will conduct benchmark tests measure power consumption overall system performance. The results study are valuable developers researchers looking for most...

It aims to study analyze performance efficiency of quantization an optimization method, well possibility training ML models directly device. Quantization involves reducing precision model weights activations while still maintaining acceptable levels accuracy. Using representative networks for facial recognition...
Abstract This work tackles the performance and energy consumption analysis of a legacy scientific application, VASP (Vienna Ab-initio Simulation Package), an application commonly used by physicists chemists for modeling materials at atomic scale. Many these applications have been implemented in Fortran, where metrics instrumentation is not straightforward. We obtained figures (execution time consumption) instrumenting source code using EML. measurement library has modified to introduce...
Modern standards in High Performance Computing (HPC) have started to consider energy consumption and power draw as a limiting factor. New more complex architectures been introduced HPC systems afford these new restrictions, include coprocessors such GPGPUs for intensive computational tasks. As increase heterogeneity, workload distribution becomes core problem achieve the maximum efficiency every component. We present Multi-Objective Dynamic Load Balancing (DLB) approach where several...

Parallel computing in heterogeneous environments is drawing considerable attention due to the growing number of these kind systems. Adapting existing code and libraries such systems a fundamental problem. The performance this affected by large interdependence between parallel architectures. We have developed dynamic load balancing library that allows be adapted for wide variety problems. overhead introduced our system minimal cost programmer negligible. strategy was applied Dynamic...
Abstract Rapid growth of demand for remote computational power, along with high energy costs and infrastructure limits, has led to treating power usage as a primary constraint in data centers. Especially, recent challenges related development exascale systems or autonomous edge require tools that will limit consumption. This paper presents capping method allows operators quickly adjust the external conditions and, at same time, reduce consumption negative impact on performance applications....

We established experimental...
We studied potential changes in the sub-ventricular zone (SVZ) stem cell niche of senescence-accelerated mouse prone-8 (SAM-P8) aging model. Bromodeoxyuridine (BrdU) assays with longtime survival revealed a lower number label-retaining cells SAM-P8 SVZ compared SAM-Resistant 1 (SAM-R1) control strain. also found that signaling is attenuated and pool less responsive to self-renewal factor pigmented epithelium-derived (PEDF). Protein analysis demonstrated stable amounts PEDF ligand niche;...

With energy efficiency one of the main challenges on way towards ultrascale systems, there is great need for access to high-quality consumption data. Such data would enable researchers and designers pinpoint inefficiencies at all levels computing stack, from whole nodes down critical regions code. However, measurement capabilities are often missing, significantly differ between platforms where they exist. A standard yet be established. To that end, this paper attempts an extensive survey...
