Jeff, A simple suggestion: put eight (or whatever the number of cores is) identical entries for each node, such as
compute-0-0 compute-0-0 compute-0-0 compute-0-0 compute-0-0 compute-0-0 compute-0-0 compute-0-0 compute-0-1 compute-0-1 compute-0-1 compute-0-1 ........... It seems to work for my dual-core nodes. -Tudor On Fri, 2007-10-26 at 09:52 -0500, Jeff Pummill wrote: > I am doing some testing on a variety of 8-core nodes in which I just > want to execute a couple of executables and have them distributed to > the available cores without overlapping.
