I am using perfsuite-0.6.1 with GNU compilers gcc and g77 and with mpich.= 1.2.7. It seems that all works properly, but when I run % /usr/local/mpich-1.2.7/bin/mpirun -np 2 psrun cpi-mpi the answer is Unrecognized argument psrun ignored. Process 0 on gemelli Process 1 on gemelli pi is approximately 3.1415926535899814, Error is 0.0000000000001883 wall clock time =3D 1.040470 What happens? Thanks in advance.

Thanks in advance. Giuseppe, This is a situation that depends on the version of MPI you are using and is a common problem. The output "Unrecognized argument" implies that the MPI launch command mpirun is interpreting psrun as an option (which it doesn't recognize and therefore ignores). You might try supplying the full pathname to psrun, for example: /usr/local/mpich-1.2.7/bin/mpirun -np 2 /usr/local/bin/psrun cpi-mpi Hope this helps, Rick p.s. I am redirecting your question from perfsuite-bugs to perfsuite-users because I think this is of general interest. |
