That seems rather slow. What version of GPFS are you running? How many nodes are you using? Are you using a "-g global shared directory"? The original mmapplypolicy code was targeted to a single node, so by default it still runs on a single node and you have to specify -N to run it in parallel. When you run multi-node there is a "-g" option that defines a global shared directory that must be visible to all nodes specified in the -N list. Using "-g" with "-N" enables a scale-out parallel algorithm that substantially reduces the time for candidate selection. -Wayne
