SIGSEGV, segmentation fault occurred

[norgeus_es]

Dear friends:
I have compiled a very simple MPI code (It write: "I am master", or "I am slave" ) by using intel fortran compiler. It was compiled and linked in a good way (ifort was used). However, when running by using: mpirun -np 2 -nolocal ./prueba_mpi, them I obtain:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

What can I do ?

What can I do ?

Besides start debugging? Did your MPI pass its own test suite, so as to verify that you got it properly built to use ifort?
Intel Cluster Tools include advanced MPI debugging tools (message checker). If you have an MPI problem, rather than a Fortran problem, in principle, the HPC forum would be more appropriate. If you have a specific problem with an MPI other than Intel, the support forum associated with that MPI would be better. If you chose an MPI without such a forum, go back and make another choice.

can you post the code?
