Delivering Modernization, Benchmarking & Cost Efficiency Migrating workloads from AMD64 to ARM64 allows organizations to harness the...

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
