PPR placement policy requests are uniform - i.e., the specified number of procs must be placed on every object of the directed type. When the request includes a cpu/proc directive, then there must also be enough CPUs to meet the request on every object. When that isn't the case, then we need to error out and not just place the proc without binding it. Signed-off-by: Ralph Castain <rhc@pmix.org>
