Djordje 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). On Apr 14, 2014, at 2:32 PM, Djordje Romanic wrote: > I compiled it
