FWIW, I filed https://svn.open-mpi.org/trac/ompi/ticket/2241 about this.
Thanks Jed!

You shouldn't need to do this in a tarball build.
Did you run autogen manually, or did you just untar the OMPI tarball and just
configure / make?

Correction on a correction; I did not goof, however zombie's remaining
is not a reproducible problem but can occur.

I goofed, openmpi does trap these errors but the system I tested them
on had a very sluggish response. However, and end-of-file is NOT
trapped.

I would recommend using derived types for big structures, or perhaps for

Thanks, I'll check out those example
Hi,
I am new in the world of MPI and I would like to ask you for the help. In my
diploma thesis I need to write a program in C++ using MPI that will execute
another external program - an optimization software GAMS. My question is
wheter is sufficient to use simply the command system(); for executi
This was "Re: [OMPI users] Trapping fortran I/O errors leaving zombie
mpi processes", but it is more severe than this.
Sorry, but it appears that at least with ifort most run-time errors
and signals will leave zombie processes behind with openmpi if they
only occur on some of the processors and no

The standard has lots of examples.

You can do this, but for small structures, you're better off just
packing buffers. For large structures containing variable
Hello, again MPU Users:
This question is similar to my earlier one about MPI_Pack/Unpack,
I'm trying to send the following structure, which has a dynamically
allocated array in it, as a MPI derived type using MPI_Create_type_struct():
typedef struct{
int index;
int* coords;
}point;

I'm using ClusterTools 8.2.1 on Solaris 10 and according to the HPC
docs,
"Open MPI includes a commented default hostfile at
/opt/SUNWhpc/HPC8.2/etc/openmpi-default-hostfile. Unless you
specify
a different hostfile at a different location, this is the hostfile
that OpenMPI uses."

You can use the 'checkpoint to local disk' example to checkpoint and restart
without access to a globally shared storage devices. There is an example on the
website that does not use a globally mounted file system:

I asked this question because checkpointing with to NFS is successful, but
checkpointing without a mount filesystem or a shared storage throws this

Hello,
It does work with version 1.4. This is the hello world that hangs with
1.4.1:

MPI_Init(&argc,&argv);
