I don't know if it is the right forum but I don't find a specific forum for IntelMPI.
Here is a sum up of the problems my custormer is currently facing:
Trying to run the job on 4 cpus on a single machine, it works fine but when he try to run the job on 2 cpus on machineA and 2 cpus on machineB it fails on machineB (whatever the machine: reversing the machine order in the host.list file, it's always the second machine which fails to run the job) with a message telling "You can't run mpdboot on machine 'name of the second machine" version of python should be >= 2.4 current version is ' ' (empty)". The job is launched from the first machine listed on the host.list file of the following command:
mpirun -f host.list -np $6 $IWRUN/bin/$NOMOS/csh_presti_ex -fl $input_data -output `pwd`/diagnostic -io_driver $_io_driver >> $IWETU/liste_presti 2>&1 ($6 is the number of cpu).
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.
