Webinar 2021 Comparing CPU, GPU, memory, interconnect and filesystem performance across National systems

Jump to navigationJump to search

Compute Canada clusters try to present the researcher with nearly identical experiences: packages, scheduler, filesystem layouts. But each cluster has differences, sometimes significant, in the particular configuration and hardware models. This presentation will compare basic "micro-benchmarks" across clusters, aiming to illustrate the basic factors that influence job performance. We'll attempt to show the diversity of performance within clusters, as well as differences between them, on measures like CPU, memory, GPU, interconnect and filesystem performance.
