Hi, I have a question about --bynode and --byslot that i would like to clarify
Say, for example, I have a hostfile #Hostfile __________________________ node0 node1 slots=2 max_slots=2 node2 slots=2 max_slots=2 node3 slots=4 max_slots=4 ___________________________ There are 4 nodes and 9 slots, how do I run my mpirun, for now I use a) mpirun -np --bynode 4 ./abcd I know that the slot thingy is for SMPs, and I have tried running mpirun -np --byslot 9 ./abcd and I noticed that its longer when I do --byslot when compared to --bynode and I just read the faq that said, by defauly the byslot option is used, so I dun have to use it rite,,, I am testing my application's performance, need to do some benchmarking...amd I doing it right by using the bynode option Or I dun mind benchmarking the byslot option, but only if I am doing it rite.... Could someone tell me
