can't apply its normal precedence rules. So...print a big "deprecated" warning for the old params and error out if a conflict is detected. I know that isn't what people really wanted, but it's the best we can do. If only the old style param is given, then process it after the warning. Extend the current map-by param to add support for ppr and cpus-per-proc, adding the latter to the list of allowed modifiers using "pe=n" for processing elements/proc. Thus, you can map-by socket:pe=2,oversubscribe to map by socket, binding 2 processing elements/process, with oversubscription allowed. Or you can map-by ppr:2:socket:pe=4 to map two processes to every socket in the allocation, binding each process to 4 processing elements. For those wondering, a processing element is defined as a hwthread if --use-hwthreads-as-cpus is given, or else as a core. Refs trac:4117 This commit was SVN r30620.
