HPCC Benchmark Performance and Cost Analysis Across Commercial Cloud Spot Instances

Abstract

This poster presents performance results and cost analysis of the High Performance Computing Challenge (HPCC) benchmark suite across diverse commercial cloud compute instances. We evaluate HPL (High Performance Linpack) performance and spot instance pricing on AMD EPYC, ARM, and Intel Xeon architectures under Amazon Web Services, Google Cloud, and Microsoft Azure. Our results reveal that x86 instances outperform ARM-based instances in raw HPL throughput, that latest CPU generations offer substantially better price-performance, and that spot pricing offers additional opportunities for reducing execution costs. These findings offer practical recommendations for researchers considering commercial cloud resources for small-scale computationally intensive workloads.
