[OMPI users] 32-bit openib btl fails on 64-bit OS

Dear All, In order to run a 32-bit program on a 64-bit cluster, one has to build 32-bit OpenMPI. Following some instructions on this mailing list, I successfully built OpenMPI 1.2.4 on 64-bit OS. However, I run into openib problem when I try to run hello_c program. I also built 64-bit Ope

Brock, Thanks much for the quick reply and information. I thought I might have been in the wrong place. :) After a google search for that list, I came up with several options. Do you happen to have a site URL or other link for the list your talking about? I want to make sure I'm on the right list

Re: [OMPI users] mpirun script and the SYNCLOC option

This if for MPICH's mpirun not OpenMPI's mpi run. You will need to direct questions to the MPICH team and mailing list. Also be aware that if that is for MPICH-1.x they nolonger develop it and should move to MPICH-2.x Or switch to another MPI stack like OpenMPI etc. Brock Palen www.umi

[OMPI users] mpirun script and the SYNCLOC option

I'm new here so forgive me if I ask any dumb questions. But the first question I have concerns the mpirun script below. My question is, what does the SYNCLOC=/bin/sync line for in the script below do, and what complications could arise (if any), from disabling this option by commenting out the lin

[OMPI users] Problem with sending vectors

I want to send vectors of myclass between nodes. But myclass has arrays inside of it. So i defined Datatype mpi_arrays to define the arrays in myclass and then i defined another Datatype for vectors. When i send vectors between nodes i get this error: [localhost:31457] *** Process received signal
