Abstract: A method and apparatus optimizes job and data distribution on a multi-node computing system. A job scheduler distributes jobs and data to compute nodes according to priority and other resource attributes to ensure the most critical work is done on the nodes that are quickest to access and with less possibility of node communication failure. In a tree network configuration, the job scheduler distributes critical jobs and data to compute nodes that are located closest to the I/O nodes. Other resource attributes include network utilization, constant data state, and class routing.
