Hello,
Would it be possible to find out from you guys exactly bench mark I should build in order to test a 16 way SMP system? And secondly, how should I then run that benchmark?
I've done the following in NPB3.2-OMP/
make bt CLASS=A
and then run(per the README-3.1 instructions)
setenv OMP_SCHEDULE "static"
setenv OMP_NUM_THREADS 16
bin/BT.A > BT.A_out.16
but the results of the test show that only 1 thread has been utilized.
I am using gcc 3.4.5 and NO mpi library.
Am I doing it correctly and/or choosing the correct version of NPB?
Has OpenMP support been merged into GCC yet? I didn't think so.
Download Intel, PGI, or Pathscale and try one of those.
Craig
Thanks,
BC
