Hi all, 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 different occasion. How should I make a reasonable performance measurement in such a case? Is it fine to get speedup/measurements on such a shared cluster? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
