Hi Greg. I am afraid that ssh rules. My feeling after 5 years of xcpu and 9 years of bproc is that people really want their ssh on a cluster. It scales well enough for the small stuff (64 or less) that constitutes most systems out there, and people don't care enough about scaling to large systems. It gives them a familiar environment. Note that the fastest machine on the planet, the Oak Ridge Jaguar system, runs sshd on every node. I had xcpu running on my XT4, and demo'd it, and it always came back to: "But it doesn't look like ssh". I think any future job spawning system for clusters has to either be ssh or feel enough like ssh that nobody knows the difference. ron
