does anyone know of an hpl like benchmark, but not mpi based, i need it to be pthreads based.
i'm seeing an issue where a user is running a pthreads program that uses a large amount of memory and many threads. the code is okay, but when it runs it's almost as if linux is confining the job to the first numa node rather then all the numa nodes. the oddity is that running a taskset -c on the program does correct the issue. i suspect numad (which i'm running) is doing something wacky, but i have yet to prove it. the user code takes a long time to run, so i was hoping i could find something else to reproduce the issue. sadly most all the benchmarks i have are mpi based. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
