Hi Johnson,
I can see the reason for the errors, that's because you enabled option
"OMPI_ENABLE_DEBUG" option in CMake GUI, and for some reason, this
option will not work properly right now.
So please just disable "OMPI_ENABLE_DEBUG", and configure/compile again,
those errors will disappear
Hello
I've a problem with a parallel execution of my personal mpi program.
When I execute it on localhost it works fine, but when I try to run it with two
machines I receive this error:
pietro@pietro-laptop:~/Scrivania$ mpirun --
prefix /home/user/MPI/ -np 4 --host u...@xxx.yyy.zzz.kkk algo1.ex
Do you get a core dump of your application on the 2nd node? You might want to
look at it and see exactly where the seg fault occurred. The stack trace that
is shown below does not include any MPI functions, suggesting that this might
be an error in your application.

As a first step, can you send your build logs so that we can verify that
OMPI+ROMIO built with proper PVFS2 support? See:

Hi, i have this program, that write the rank of a process on a file. Every
processes write the rank on the same file. Whe i try to read that value, is
always zero.

I don't know whether its relevant for this problem or not, but a couple
of weeks ago we also found that we had to apply the following patch to
to compile ROMIO with OpenMPI over pvfs2. There is an additional header
pvfs2-compat.h included in the ROMIO version of MPICH, but is somehow
missing in
Hello Luís,
You opened the file with write-only mode which causes the subsequent read
to fail - although I do not know why the error checking fails to see that.
If you change MPI_MODE_WRONLY to MPI_MODE_RDWR then your code works fine.

I noticed you never checked the return code from your MPI_File_read
statement. If you had used your own mpi() function, it would state
something like this:
MPI_FILE_READ(116): Cannot read from a file opened with amode MPI_MODE_WRONLY

Hi,
when running the configure script it breaks with:
configure: error: Could not run a simple Fortran 77 program. Aborting.
(logs with details attached)
I don't know how to interpret this error since I already successfully compiled
fortran code using these compilers(gcc/gfortran 4.5).

Does your application do a lot of printing to stdout/stderr?

Christoph,
It looks like you need to add -L/usr/local/lib to the fortran and f90
flags, either on the configure input or in the environment variables,
so that the loader can find libgfortran.

More likely the difference is due to the fact that MPICH does some automatic
process binding and OMPI doesn't. There have been a number of discussions on
this list about this issue. You might search the list for "MPICH" to find them.
See the OMPI FAQ on affinity:
http://www.open-mpi.org/faq/?ca
I don't know how i dind't see that. :)
I guess i'm still a noob in MPI.
Thanks for the help
