Re: [PerfSuite-users] perfsuite and mpi

[Rick K. <rk...@nc...>]

Giuseppe,

You will want to include -lpshwpc and -lperfsuite in your link line,
after the -lpshwpc_mpi.  Those libraries have the externals that are 
missing.

Also, just to clarify, libpshwpc_mpi is a PMPI-based interface.  There is
no need to add any calls to PerfSuite if you link with that (it's likely
it will result in a runtime error, actually).

So in summary:

If you add calls to pshwpc (as you have done):

   -lpshwpc -lperfsuite -lpapi

If you do not, and it is an MPI program:

   -lpshwpc_mpi -lpshwpc -lperfsuite -lpapi

Plus you may need to adjust the MPI libraries linked in for the MPI 
profiling interface, which is independent of PerfSuite.

Good luck,
Rick
