The problem just appeared after a recent update of the system (debian) on our cluster. The code was working perfectly before the update but now I cannot run jobs in parallel anymore. MPI works with other softwares, but not with NEK. In particular I have the following problem:<br><br>When I execute a parallel run using the script nekmpi eddy_uv 4 <br><br>the command execute 4 different jobs running on a single processor rather than a single job running on 4 processors. I attach the log to this mail (log.out) . After a few second three jobs are killed and only one remains active. A similar problem was also found on a new machine with a fresh installation of debian. It seems that the scripts is not able to set the correct value of the variable np (or_np).<br>Anyone found a similar problem ? Any explanation for such behavior ? Any advice to solve the problem ? <br><br>Thanks in advance <br><br><br>Flavio<br><br><br></body></html>
