Hi all,
After looking at the problem with Sergio in a separate mail, we found
that the problem was "slurm_init_job_desc_msg" call. It sets default
values to all the objects of job_desc_msg_t, so it was overwriting
previous values. It has been moved just after the variable
declaration, and now everything works as expected.
I am writing this mail so anybody with the same problem landing on
this thread can read our solution.
Best regards,
Manuel
