Yes, it's a program that was wrriten and compiled by the user. I put a priority for this user in file /etc/security/limits.conf. I wonder is there is a way to put a quota for CPU % a user is allowed. The only thing that I saw that can be set there is Max CPU Time. Or is that the same thing? Forgive my ignorance. here part of my /etc/security/limits.conf #<item> can be one of the following: # - core - limits the core file size (KB) # - data - max data size (KB) # - fsize - maximum filesize (KB) # - memlock - max locked-in-memory address space (KB) # - nofile - max number of open files # - rss - max resident set size (KB) # - stack - max stack size (KB) # - cpu - max CPU time (MIN) # - nproc - max number of processes # - as - address space limit # - maxlogins - max number of logins for this user # - priority - the priority to run user process with # - locks - max number of file locks the user can hold username hard priority 100000 What else can I add here?
