[Wrf-users] How to set environmental variable for MPI libraries

[Tabish Ansari]

Hello

I am trying to compile WRF/chem in dmpar mode. I believe I already have the
mpi libraries on my server. The following info must be useful in responding:

ce12s023 at c1hn1:~> which mpif90
/sware/intel/impi/4.1.0.024/bin64/mpif90
ce12s023 at c1hn1:~> which mpicc
/sware/intel/impi/4.1.0.024/bin64/mpicc
ce12s023 at c1hn1:~> which mpirun
/sware/intel/impi/4.1.0.024/bin64/mpirun

/sware/intel/impi/4.1.0.024
ce12s023 at c1hn1:/sware/intel/impi/4.1.0.024>

Now, after seeing that information please suggest that at what level should
I set the environmental variable to? kindly mention the exact command in
bash mode.

Thanks in advance!
