OK, it works although there are some temporary errors. This is the NetBSD wip openmpi package as downloaded from the webCVS a couple of days ago but with my patches as detailed before (I have not tried comparing yours with mine as yet) and the removal of the compilation and install of the Vampire

Hi Gus, Thanks for your ideas.. I have a few questions, and will try to answer yours in hopes of solving this!! Should I worry about setting things like --num-cores --bind-to-cores? This, I think, gets at your questions about processor affinity.. Am I right? I could not exactly figure out th

ere - so it is working on NetBSD ! I am currently installing the PkgSrc build, having prevented the install binary clash, and will post the results of that soon. I have placed the tar of current patches from our PkgSrc build in http://www.ecs.vuw.ac.nz/~kevin/forMPI/openmpi-1.3.4-20091208-netbsd.

Hi Matthew More guesses/questions than anything else: 1) Is there any additional load on this machine? We had problems like that (on different machines) when users start listening to streaming video, doing Matlab calculations, etc, while the MPI programs are running. This tends to oversubscribe

[OMPI users] OMPI as a batch system

2009-12-08 Thread Ross Boylan
What is the difference between running a set of programs with independent invocations of mpirun vs specifying --app? The programs do not need to talk to each other. I think that if one job fails it will take the others down if I use --app. Is that correct? This is the main reason I'm considerin

Whilst MPI has traditionally been run on dedicated hardware, the rise of cheap multicore CPUs makes it very attractive for ISVs such as ourselves (http://www.cambridgeflowsolutions.com/) to build a *single* executable that can be run in batch mode on a dedicated cluster *or* interactively on a
