Probably something that looks like Red Hat. All these codes will use some form of message passing with MPI being the most common. Finally to get on node parallelism some codes will hand write cuda for their problem and others can get away with calling Nvidia libraries or using something like new versions of OpenMP.
- ttul 8y agoI want to see the output of “top”
- quadruplebond 8y agoUnfortunately you would be disappointed. top is only going to display what's running on your current node, not the whole machine. There is probably some sort of global top, but just logging in and running top in your shell will only run top on the head node. That head node might still be beefy, but only as beefy as a large shared memory machine can be.
- ikeyany 8y agoWhy not just fork a child top for each node?
