Abstract:We present the design and implementation of ALPS, a per-application user-level proportional-share scheduler. It provides an application with a way to control the relative allocation of CPU time amongst its individual processes. The ALPS scheduler runs as just another process (belonging to the application) at user level; thus, it does not require any special kernel support, nor does it require any special privileges, making it highly portable. To achieve efficiency, ALPS delegates fine-grained time-slicing resp… Show more
