Hi Ahmed,
You may also want to look into running Linpack benchmark tests.

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.
Thx!
