Arthur,
Your email does not contain enough information to pinpoint the problem.
However, there are several hints that tent to indicate a problem in your
application.
1. in the collective communication that succeed, the MPI_Intercomm_merge,
the processes are doing [at least] one MPI_Allreduce foll
Artur,
do you check all the error codes returned by MPI_Comm_spawn_multiple ?
(so you can confirm the requested number of tasks was spawned)
since the error occurs only on the first MPI_Send, you might want to
retrieve rank and size and print them right before MPI_Send, just to make
sure the comm
Artur,
in OpenMPI, MPI_Comm is an opaque pointer, so strictly speaking, high value
might not be an issue.
can you have your failed processes generate a core and post the stack trace
?
btw, do you MPI_Send on the intra communicator created by
MPI_Intercomm_merge ?
what is the minimal config neede
Hi,
I have a problem with my application that is based on dynamic process
management. The scenario related to process creation is as follows:
1. All processes call MPI_Comm_spawn_multiple to spawn additional
single process per each node.
2. Parent processes call MPI_Intercomm_merge.
3. C
Just pushed a change that renamed the field - hopefully fixed now
Thanks!

It's defined as "(&__iob[0])" on Solaris 10; it's just #defined
differently by glibc. See stdio.h(7posix).
a field from orte_iof_proc_t is named "stdin"
could stdin be #defined under the hood in Solaris ?
if so, then renaming this field should do the trick.
I will double check that on Monday
Cheers,
Gilles

I’m afraid I have no idea what Solaris is complaining about here.

Hi,
yesterday I tried to build openmpi-dev-3498-gdc4d3ed on my
machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux
12.1 x86_64) with gcc-5.1.0 and Sun C 5.13. I was successful on
my Linux machine, but I got the following errors on both Solaris
platforms.
Sun C 5.13:

Best options for debugging something like this are: -mca odls_base_verbose 5
-mca errmgr_base_verbose 5
It’ll generate a fair amount of output, so try to do it with a small job if you
can. You’ll need a build configured with -enable-debug to get the output.
