Re: [OMPI users] OpenMPI v3.0 on Cygwin

The MS-MPI developers disagree with your statement below and claim to be actively working on MPI-3.0 compliance, with an expected new version release about every six month. - Jeff Jeffrey A. Cummings Engineering Specialist Performance Modeling and Analysis Department Systems Analysis

Re: [OMPI users] OpenMPI v3.0 on Cygwin

The OpenMPI developers stopped supporting Windows a long time (several major versions) ago. Microsoft has a free version of MPI for Windows available for download. There's no guarantee it will be free forever but it is free for now. I've been using it for about a year and it works for me.

[OMPI users] MPI_Finalize?

What does MPI_Finalize actually do? Would it be harmful to synchronize all processes with a call to MPI_Barrier and then just exit, i.e., without calling MPI_Finalize? I’m asking because I’m getting a segmentation error in MPI_Finalize. – Jeff Jeffrey A. Cummings Engineering Specialist

Re: [OMPI users] Problem moving from 1.4 to 1.6

I've tried that parameter, but with the order self,sm,tcp. Should this behave differently than the order you suggest? Jeffrey A. Cummings Engineering Specialist Performance Modeling and Analysis Department Systems Analysis and Simulation Subdivision Systems Engineering Division Engineering

[OMPI users] Problem moving from 1.4 to 1.6

Can anyone suggest what the problem might be? Did the relevant syntax change between versions 1.4 and 1.6? Jeffrey A. Cummings Engineering Specialist Performance Modeling and Analysis Department Systems Analysis and Simulation Subdivision Systems Engineering Division Engineering and Technology

Re: [OMPI users] Windows support for OpenMPI

I would be disappointed to see the Windows support go away. I use it mostly for debugging, but it's valuable to me for that purpose. - Jeff Cummings From: Durga Choudhury To: Open MPI Users List-Post: users@lists.open-mpi.org Date: 12/07/2012

[OMPI users] Segmentation fault during MPI initialization

I've been having an intermittent failure during MPI initialization (v 1.4.3) for several months. It comes and goes as I make changes to my application, that is changes unrelated to MPI calls. Even when I have a version of my app which shows the problem, it doesn't happen on every submittal.

[OMPI users] Array version of MPI_Iprobe?

MPI_Iprobe returns a single status object if at least one message is waiting in a queue. I would like to be able to do something similar (i.e., non blocking probes) which would produce an array of status objects representing all messages waiting in a queue. I would then decide on the order

[OMPI users] Socket ports

I'm attempting to launch my app via mpirun and a host file to use nodes on multiple 'stand-alone' servers. mpirun is able to launch my app on all requested nodes on all servers, but my app doesn't seem to be able to communicate via the standard MPI api calls (send , recv, etc). The problem

Re: [OMPI users] Urgent Question regarding, MPI_ANY_SOURCE.

It strikes me that you should be able to use the tag to identify the message that is to be received. In other words, you receive a message from any source but with a tag that identifies the message as containing the load value that is expected. - Jeff From: Jeff Squyres

[OMPI users] Problem with prebuilt ver 1.5.3 for windows

I'm having a problem using the prebuilt Windows version 1.5.3 with my app built with MS VisualStudio 2010. I get an error message (for each node) that says: "The procedure entry point InterlockedCompareExchange64 could not be located in the dynamic link library KERNEL32.dll". I'm running

[OMPI users] OpenMPI version syntax?

I've encountered a supposed OpenMPI version of 1.4-4. Is the hyphen a typo or is this syntax correct and if so what does it mean? - Jeff

[OMPI users] How closely tied is a specific release of OpenMPI to the host operating system and other system software?

I use OpenMPI on a variety of platforms: stand-alone servers running Solaris on sparc boxes and Linux (mostly CentOS) on AMD/Intel boxes, also Linux (again CentOS) on large clusters of AMD/Intel boxes. These platforms all have some version of the 1.3 OpenMPI stream. I recently requested an
