I tried this, but I get an error, ------- An invalid value was given for the number of processes per resource (ppr) to be mapped on each node:
PPR: 12:node,span The specification must be a comma-separated list containing combinations of number, followed by a colon, followed by the resource type. For example, a value of "1:socket" indicates that one process is to be mapped onto each socket. Values are supported for hwthread, core, L1-3 caches, socket, numa, and node. Note that enough characters must be provided to clearly specify the desired resource (e.g., "nu" for "numa").
