> This might be of interest to Reuti and you : it seems that we cannot reproduce the problem anymore if we don't provide the "-np N" option on the orterun command line. Of course, we need to launch a few other runs to be really sure because the allocation error was not always observable. Actually, I recently understood (from Reuti) that the tight integration mode would supply every necessary bits to the launcher and thus I removed the '-np N' that was around... Could it be that using the '-np N' while using the sge tight integration mode is pathologic ?
No, it should work just fine. Sounds like something weird is going on.
[eg: ] ok, then let me know when you'll got some time to spend on this issue, I'll be glad to help.
