How do I find the correct environment variables for MPI?
Hello all. I've been trying to install NWCHEM in parallel on a new cluster, and have been able to get it to work on single processors by ignoring any MPI environment variables.
This is, of course, pretty worthless. So I'm starting over and trying to get thing set up right for the MPI. The key variables are:
As far as I can tell, the MPI_INCLUDE is supposed to be the place where the mpi.h and/or mpif.h are which I think I have correctly. Also, the MPI_LIB is mean to have all of the libmpixxxxxetc, right? That leaves LIBMPI,which I THOUGH was supposed to be the location of the libmpi.so file, but when I set it that way and try to compile I get:
I get this error whether I include the "libmpi.so" part in the path or not. It appears that it's not finding what it needs in that folder, but then what is it that it's supposed to find?
Thanks for any help.

Sorry for the lack of proper code.
Is this in the correct forum? Is there a parallel forum that I'm missing?

The commented line should not be commented. This is what my LIBMPI was set to. I tried it both with the .so file in the path and without and got the same error message.
