I think you can't do that. What you can do is modifying priority for user. You can do that by editing file /etc/security/limits.conf:

john hard priority 20

Sets priority for john's processes to 20 (effective after next login). 20 is lowest priority.

This way john can use 100% of CPU, but if someone else needs it, other user will immediately get it, and john's tasks will wait (or actually slow down, not stop completely).

effective after next login does that refer to next ssh login or next system reboot? – xxx374562 – 2018-10-23T01:08:29.683

Not exactly what i am looking for. But since the other thing can't be done, i guess i'll have to work with this. Thanks a lot :). – tapan – 2011-02-18T05:17:24.250
