Greetings, I believe the number of nodes (-nodes = integer) forces the number of nodes on which the specified number of CPUs will be used; in other words it is designed for cases where you want to force all your calculations to land on a single node to minimize the inter-node message pass. if you need more CPUs you need to specify that in the BATCH file ( -ntask = integer).
