This is done using IntelMPI2.0 (which is, I know obsolete) but trying IntelMPI3.2 there is no error message but no jobs start either on machineA or machineB (even with verbose and debug option). We ask him to set the envronment variable I_MPI_DEBUG to 7 and we are waiting for the result of this test.
It seems that the problem seems related to a test in mpdboot.py inplying the function getversionpython.
NB The tests have been done using both rsh and ssh with the same results.
Thanks a lot for any suggestion.
I'm moving this to the correct forum. We are sorry for the delay.
Intel MPI Library is a fully supported product, so your customer can also seek help here: http://software.intel.com/en-us/articles/intel-mpi-library-support-resources/
Intel Software Network Support
Starting with Intel MPI Library 3.2, all python checks have been disabled at startup. I actually think this points to a possible configuration issue with the system. Because, as you point out, version 2.0 is no longer support, I'd suggest you continue your experiments with 3.2.
Are the two nodes setup to use passworldless ssh? Meaning, can you log in from node1 to node2 (and vice versa) without being prompted for a password? If no, then the customer needs to set that up as it's a requirement for Intel MPI. Do you get any other prompts (e.g. RSA authenticity host checking)?
It'll also be good to do "mpdboot -d -v -r ssh -n 2 -f host.list" and provide the output. This will give more verbose information on what's going on during startup.
Looking forward to hearing back from you.
