Re: [OMPI users] Problems running openmpi under os x

Brian, I think it's just a symbol clash. A test program linked with just mpicxx works fine but with our typical link, it fails. I've narrowed the problem down to a single shared library. This is from C++ and the symbols have a namespace casa. Weeding out all the the casa stuff and some o

[OMPI users] read send buffer before a send operation completes

It's prohibited by the standard to read send buffer before a send operation completes, and I understand the theoretical rationale behind it. I'm currently layering a protocol stack on top of MPI, and this protocol allows a buffer to be read by multiple peers concurrently. Thus for strict conforma

Re: [OMPI users] Windows Build

Hello Tisham, Currently the Open-MPI implementation for windows is still not finalized, HLRS and UTK are working together on this project. We have made solution and project files for Visual Studio 2005, and need more test and modification. If you need more information about this, please jus

Re: [OMPI users] read send buffer before a send operation completes

At the moment, I believe that this should be safe in Open MPI (read a buffer that is currently being sent). No claims about the future, though. :-) On Jul 12, 2007, at 1:07 AM, Isaac Huang wrote: It's prohibited by the standard to read send buffer before a send operation completes, and I

Re: [OMPI users] mpi with icc, icpc and ifort :: segfault (Jeff Squyres)

I admit to being baffled. :-( If general C++ applications seem to be working with icc/icpc, I do not know why OMPI would fail for you with icc/icpc (especially while accessing stack memory). What version of icc/icpc are you using? There were some bugs in the 8.x series that caused proble

Re: [OMPI users] Can't get TotalView to find main program

Thanks for the reply Jeff. Yes, I did compile my test app with -g, but unfortunately, our rpm build process stripped the symbols from orterun, so that turned out to be the culprit. Once we fixed that and used openmpi-totalview.tcl to start things up, TotalView debugging started working. Unfortuna

Re: [OMPI users] Can't get TotalView to find main program

Dennis, The message queue feature is not yet available on the 1.2.3. One should use the latest version (from svn trunk or from the nightly builds) in order to get it. I'll make sure it get included in 1.2.4 if we release it before the 1.3. Thanks, george. On Jul 12, 2007, at 3:34 P

Re: [OMPI users] Correction to FAQ: How do I build BLACS with Open MPI?

The INTFACE is for the namespace interface in order to allow the Fortran code to call a C function. So it should be dependent on the compiler. Btw, for some reasons I was quite sure we generate all 4 versions of the Fortran interface ... If this is true is doesn't really mater what you have
