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

Introduction: High-Performance Linpack (HPL) is a widely used benchmark for testing the computational performance of computing systems. In this blog post, we explore an intriguing scenario where we conducted HPL tests on two ARM64 machines. Surprisingly, the Host-2 machine exhibited a 20% lower performance than the Host-1 machine in the HPL test. Intrigued by this result, we embarked on a journey to comprehensively diagnose the underlying cause of this performance discrepancy
