I am usually running my parallel jobs on the university cluster of several
hundred nodes (accessible to all). So often I observe very different total
MPI_Wtime value when I run my program (even of same problem size) on
How should I make a reasonable performance measurement in such a case? Is it
fine to get speedup/measurements on such a shared cluster?
