PICO: Performance Insights for Collective Operations

Published 22 Aug 2025 in cs.DC and cs.PF | (2508.16809v1)

Abstract: Collective operations are cornerstones of both HPC application and large-scale AI training and inference. Yet, comprehensive, systematic and reproducible performance evaluation and benchmarking of said operations is not straightforward. Existing frameworks do not provide sufficiently detailed profiling information, nor they ensure reproducibility and extensibility. In this paper, we present PICO (Performance Insights for Collective Operations), a novel lightweight, extensible framework built with the aim of simplifying collective operations benchmarking.
