Hi, There is a new version of mpiexec available at http://www.osc.edu/~djohnson/mpiexec This program is intended to be a replacement for the mpirun scripts used with the ch_gm device for Myrinet. Mpiexec uses the task manager library of PBS to spawn copies of the executable on all the nodes in a PBS allocation. The goals of the program are as follows, -Integration of parallel jobs into PBS. -Proper accounting and enforcement of cpu time and resource use for parallel jobs (all processes are children of pbs_mom, of course there are ways around it). -More scalable, reliable parallel job startup for clusters. * There are limitations the program. The tm layer is not reliable enough for large processor count parallel jobs. There's a patch included against pbs-2.2p11. It is possible to modify the program for use with other MPICH devices. This program is distributed under the GPL, see the LICENSE file included with the program. -- Doug Johnson Systems Developer/Engineer The Ohio Supercomputer Center [email protected]
