[OMPI users] hang in mpi_allreduce in single linux machine‏

Hi, When I ran multiple processes in a single machine, the programs are hanging in mpi_allreduce in different points during different runs. I am using 1.3.4. When I used different machines to run the processes, it is OK. Also, when I recompiled open mpi in debug mode, the problem goes

That's a really good idea. The trouble is that I need to have multiple versions installed (eg. compiled with the various compilers), so I think I still need to manipulate name in some way, so the packages will be named differently. But _prefix should definitely give me more flexibility as to

Hmm. I'm not sure why --rebuild is different than not--rebuild. I'm not an RPM expert, though... On Jun 26, 2012, at 4:24 PM, Lloyd Brown wrote: > Something else interesting that I just discovered. If I do this, I have > the problem: > > rpmbuild --rebuild -bb path/to/openmpi-1.6-2.src.rpm

Re: [OMPI users] MPI Problem

It seems that the problem is solved. Actually, when I replaced "use mpi" by "include "mipf.h". And adding -lmpi -lmpi90, everything works.  I think you need these two "-lmpi -lmpi90" when you have Blas or LAPACK libraries. Regards, Ali From: Jeff Squyres

Re: [OMPI users] undefined reference to `netcdf_mp_nf90_open_'

Per other replies on this thread, I think you're missing some -l (and possibly -L) options on your compile line. You probably don't need --showme to see exactly what mpif90 is doing because it looks like the issue is not with mpif90, but rather with the arguments that you're passing to it.

Re: [OMPI users] undefined reference to `netcdf_mp_nf90_open_'

Dear Dima I was not sure but it seemed to be like something related to netcdf and mpif90. I have struggling with the compilation of comso, int2lm parallel has been installed successfully but cosmo is giving this error. I don't have any -lnetcdf or -lnetcdff in linker options of the Fopts file. I

Re: [OMPI users] undefined reference to `netcdf_mp_nf90_open_'

Dear Jeff Can you explain a little how to get this. "* you can take the mpif90 command that is being used to generate these errors and add "--showme" to the end of it, and you'll see what underlying compiler command is being executed under the covers."* * * Regards Ahsan On Tue, Jun 26, 2012 at

Hi, Could you please compare the output from "mpif77/mpif90 -showme" when executed from the command line and from inside the Makefile? Could you also check that the argument to MPI_INIT is a normal INTEGER and is not getting some funny KIND or preprocessor treatment? Regards, -- Hristo

Re: [OMPI users] MPI Problem

Something strange, By adding all the libraries which I found from mpif90/mpif77 --showme, Fortran 77 version worked finally, but Fortran 90 version still has the problem. Error: There is no specific subroutine for the generic 'mpi_init' at (1) any idea??
