Answer from our expert:
If we want to evaluate perf of CPU, we can use something like DGEMM, DAXPY for computational intensive or memory intensive performance. These are not MPI application. So they only check pure CPU performance. We can use MPI to run them on multiple nodes and check perf at the same time.
Another way (if include MPI performance), then we can use HPL. Again, this mostly depends on DGEMM performance plus some MPI communication performance.
Or you can use HPCG. This includes something like DGEMM (actually more like SpMV) and memory intensive perf and also more MPI perf.
