Hello, Please note, that one of the reasons may be non-equivalent allocations. DMTCP cannot restore processes that was originally running on the same node to be on different nodes. This means that if you originally requested the following allocation: cn[0-1], ppn = 4 and trying to restart on cn[0-4], ppn = 2 this won't work even though the allocations are logically equivalent.
