Dear users of this mailing list,
I have a problem with virtual memory setting to ulimited:
When I type within a shell I get:
bash#: ulimit -v
unlimited
But:
bash#: qrsh ulimit -v
3932160
Where do I set the value within the SGE to unlimited? I just tried it to
set it within the startup-script of the client daemons, but without
success. Maybe it is correlated to h_vmem which is limited to 45 G/host?
Here the output of the settings:
[root@master~]# qhost -F -h f37
