Why? What would it tell you? I mean, other than “42”.
Quite a bit about what sort of performance and variability can be expected for latency-sensitive jobs. Facilities publish HPL numbers despite far less relevance to application needs. People currently write proposals for Supercomputer X, and only find post-award that it delivers latency regressions compared to Humblecomputer Y and thus isn't suitable for the planned workload, so they fabricate a different workload to use the allocated hours.
