Its about 8x faster on Linux to use the loopback device for communication between processes of parallel jobs using an MPI library. That's why I ask. This is a support list isn't it? That would make it the right place to ask such questions now wouldn't it. If you find that funny you can go elsewhere. Dave On Fri, Jun 29, 2001 at 11:57:36PM -0700, Crist J.
