Hi, the goal of my gsoc project is to enable the system administrators to configure %CPU limits using the rctl command. So that they can for example limit a particular user to 50% cpu time. Last week I implemented a new way to calculate %cpu usage for short-lived processes or early stages of longer processes. Basicly, I divide process cpu time by the process wall clock time. This week I am working on a mechanism that decays %cpu usage of terminated processes. This is slightly different than my previous approach, where I simply removed the %cpu from the respective racct containers when the process terminated. rudo
