We conducted SPDK bdevperf tests on an AWS EC2 r8gd.metal-24xl instance, focusing on single CPU core performance under high I/O load. Our objective was to demonstrate a CPU-bound workload. Results show low I/O wait and high CPU utilization, confirming the CPU is the limiting factor. The 2-disk configuration achieved the highest throughput, indicating a CPU saturation point. 1. Performance Results Summary  (100-second duration) Below is a consolidated view of our 100-second bd

Benchmarks are vital for evaluating High-Performance Computing (HPC) system performance, guiding hardware choices, and optimizing software. This whitepaper focuses on understanding and overcoming bottlenecks in HPC benchmarks for CPU environments, specifically considering ARM/AARCH64 architectures, using miniFE and GROMACS as examples. 1. Introduction to miniFE and GROMACS Benchmarks 1.1. miniFE: A Finite Element Mini-Application miniFE, part of the Mantevo suite, simulates i

Basic Linear Algebra Subprograms(BLAS) and BLAS Like Interface Software(BLIS) are libraries that can accelerate mathematical operations on current CPU microarchitectures. As a part of the FLAME project , BLIS was introduced to handle the dense linear algebra software stack. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operatio
