[OMPI users] check point restart

state to start again. I seem to remember a simpler approach (check point restart?) in which the state of the .exe code is saved and then simply restarted from its current position. Is there something like this for restarting an mpi program? Thanks, Erik -- Erik Nelson Howard Hughes Medical

I may have deleted any responses to this message. In either case, we appear to have fixed the problem by installing a more current version of openmpi. On Thu, Feb 14, 2013 at 2:27 PM, Erik Nelson wrote: > > I'm encountering an error using qsub that none of us can figure out. MPI >

[OMPI users] qsub error

qsub for the "hello world" program. These don't look like MPI errors, but rather some conflict with, maybe, secure communication accross nodes. Is there something simple I can do to fix this? Thanks, Erik Nelson Howard Hughes Medical Institute 6001 Forest Park Blvd., Room ND10.124

Re: [OMPI users] restricting a job to a set of hosts

s, I automatically send all processes (parent and child, or master and slave if you prefer) to the specified list of hosts. Reading your email below, it looks like this was the correct understanding. On Thu, Jul 26, 2012 at 5:20 PM, Reuti wrote: > Am 26.07.2012 um 23:58 schrieb Erik Nelson: >

[OMPI users] restricting a job to a set of hosts

mpirun -np 101 -nolocal ./executable I would like to restrict the job to nodes compute-5-1 to compute-5-32 on our machine, each containing 8 cpu's (slots). How do I go about this? Thanks, Erik -- Erik Nelson Howard Hughes Medical Institute 6001 Forest Park Blvd., Room ND10.124 Da
