Hi, nodes without memory will currently be disabled by also moving the physical cores connected to them to other nodes. This leads to nodes without CPUs and thus to a division by zero in the node allocation algorithm. Attached patch fixes this by checking for 0 before the division. This fixes domain creation on boxes with memory-less nodes. The resulting domain distribution is still not correct, I will send another patch after more testing. Regards, Andre.
