Re: [OMPI users] Using OpenMPI on a network

Just finished doing that. Still getting the same error. How do I make sure there are no old builds/files left? I uninstalled everything to do with MPI, Cygwin, cleared environment variables, did the whole Windows build again and then did the supercomputing tutorial. -- Vimal From:

That's a little bit strong - OMPI still supports checkpoint/restart as a fault tolerance mechanism. There really isn't anything the sys admin has to do, though - what is required is that users periodically order their programs to checkpoint so they can be restarted after a failure.

Re: [OMPI users] Using OpenMPI on a network

There's something else wrong, if that's the Supercomputing Blog tutorial 1 you're running. It works happily without a hostfile. I think you have some borked paths there. I don't know why a Windows version is looking for an etc directory for a hostfile, unless there's some of your previous

It has been clearly stated that the official position pushed forward by a majority of the Open MPI developer community is that fault tolerance is not needed so we (read this as the official version of Open MPI) do not support it. However, a group of researchers have been working toward a

Is hostname the name of the system I'm running it on? Just tried that. Got the same error message -- Vimal From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On Behalf Of Ralph Castain Sent: Tuesday, June 19, 2012 1:03 PM To: Open MPI Users Subject: Re: [OMPI users]

Re: [OMPI users] Using OpenMPI on a network

You're getting that error because you failed to specify any hosts on your cmd line - so OMPI has no idea where to launch the procs. It looked for a default hostfile, but didn't find that either. Just add a -host option to your command line and tell it where you want the procs to run. On Jun

Hi all,Can anyone explain me the fault tolerant features in OpenMPI? I've read the FAQs and some papers about this topic listed in open-mpi.org, but still can't figure out when one node of my supercomputer system fails down during computing, what would happen with the fault tolerant mechanism

[OMPI users] checkpointing of NPB

Dear, Please help. I configured the open mpi and it can checkpoint HPL. However, whenever I want to checkpoint NAS parallel benchmark it kills the application without informative message. Please how do I configure the openmpi 1.6 to checkpoint NPB? I really need a help, I have been on this
