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?
 
Thanks,
BC
