I don't think this application runs as a parallel application in thread mode. There is only one process (in thread mode, ps/top commande line display thread processes) which bypass the limits.conf configuration.
Normally the process shoud be killed if the memory limit will be reach ? Thanks. Le 20:59, m.roth@xxxxxxxxx a écrit :

We had a problem like that - a user on a 48-core system that proceded, as the final step of the job, to want half again as much memory as the system had (256G!!!). After discussions, he limited what he submitted, so that's why I wondered if you could control that administratively. mark
