Colloquium 2023 Performance: current and upcoming systems

Jump to navigationJump to search

The next year or two will bring major updates to the ARC resources available to Canadian researchers. We know only some of the outlines of possible hardware configurations, based on what vendors are talking about today. But we know many of the basic directions, and it's interesting to consider how they compare to our current hardware. This talk will focus on current hardware, to show the relation between hardware-level (theoretical) performance, then micro-benchmarks, and how those lead to some application-level metrics. From that context, we can make some extrapolations about the kind of performance we can hope for in upcoming systems.
