OK guys... Thanks for all this info. Frankly, I didn't know these diferences
between OpenMP and OpenMPI. The commands:
which mpirun
which mpif90
which mpicc

Your WRF configure file seems to use mpif90 and mpicc (line 115 &
following).
In addition, it also seems to have DISABLED OpenMP (NO TRAILING "I")
(lines 109-111, where OpenMP stuff is commented out).
So, it looks like to me your intent was to compile with MPI.
Whether it is THIS MPI (

This can also happen when you compile your application with one MPI
implementation (e.g., Open MPI), but then mistakenly use the "mpirun" (or
"mpiexec") from a different MPI implementation (e.g., MPICH).

I compiled it with: x86_64 Linux, gfortran compiler with gcc (dmpar).
dmpar - distributed memory option.
Attached is the self-generated configuration file. The architecture
specification settings start at line 107. I didn't use Open MPI (shared
memory option).
