I wonder if there would have been an opportunity to generate some finer-grained benchmarks with something like BiCGStab+ILU (or maybe CG+incomplete cholesky). Instead of CG+Gauss Seidel. The pitch being, you might have made different memory vs compute trade-offs with designing your cluster, but you should be able to select a fill-in factor for the preconditioner to suit it.
- jandrewrogers 4mo agoI think you could build more representative benchmarks that capture capability better. The tension is that HPC companies are pure hardware companies and you need a lot of help from software to make your hardware look good. They don’t like that. Most of our software sucks at the scales they try to benchmark. Ironically, the related Graph500 benchmarks reflect this better. Performance is dependent more on using the hardware better than better hardware per se.
