Apologies for the back to back posts, but it recently became apparent that I needed to install SPECFEM3D on another machine than what I am currently using. The new machine does not appear to have mpirun, however it does have mpiexec installed. I thought mpiexec could work as a substitute for mpirun since it can act as a replacement, but i have found that this is apparently not the case.
./configure FC=gfortran CC=gcc MPIFC=mpif90
can we substitute mpif90 with mpiexec? I have tried simply running ./configure MPIFC=mpiexec, letting it find the other compilers itself, but this causes failure when the code attempts to use mpi during the examples. Any advice is appreciated. I would like to install mpirun, but have been told by the IT that it would take months to do so on their end.
