This paper addresses job scheduling for parallel supercomputers. Modern parallel systems with n nodes can be used by jobs requesting up to n nodes. If less than n nodes are requested, multiple jobs can be run at the same time, allowing several users to use the system. One of the challenges for the operating system is to give reasonable service to a diverse group of requests. A single 1-node job that is running for a long time may effectively block the whole machine if the next job requests all… CONTINUE READING
