MPI_FINALIZE fails with error: rank 0 unable to connect to rank 1
MPI_FINALIZE fails with error: rank 0 unable to connect to rank 1
- Hi all,
I have MPI fortran code that I would like to run on two computers, one my home computer , the other work, connected through VPN. I run mpiexec with two hosts and I get the output from the program but MPI Finalize crashes with the above error message. job aborted:
rank: node: exit code[: error message]

I set MPICH_NETMASK to the correct IP but it doesnt seem to make a difference.
Does anyone have a hint for me? Let me know if you need more information...

Hi Benjamin,
What version of MPI are you using? (MSMPI v1, v2? MPICH2??)
seems that your name resolution is failing; try using the ip address of your machines on the mpiexec command line, instead of the hosts names.
