Hi Ralph,
I've downloaded and tested the openmpi-1.7a1r22817 snapshot,
and it works fine for (multiple) spawning more than 128 processes.
That fix will be included in the next release of OpenMPI, right ?
Do you when it will be released ? Or where I can find that info ?
Thank you,

HI !
have you ever did some analysis to understand if there is a limitation in
the number of nodes usable with OpenMPI-v1.4 ?
Using also the functions MPI_Comm_spawn o MPI_Comm_spawn_multiple.
Thanks,
Federico
Hi everyone !
I have to submit you a question,
I write a little code that does and MPI_Comm_spawn_multiple on a specific
set of node.
The node where to run on are specified using the "host" attribute of the
MPI_Info object.
That attribute is filled with the string get from MPI_Get_processor_name.
Look at
http://www.boost.org/doc/libs/1_40_0/doc/html/boost/mpi/intercommunicator.html
to have a Boost wrapper for an Intercommunicator.

Well from what I know Boost.MPI contains only MPI-1 functions
(but refer to the boost mailing list for support
http://lists.boost.org/mailman/listinfo.cgi/boost-users);
so Intercommunicators are not managed by the Boost.MPI library, and you
have to use the stardard MPI functions.
So, by now, I th
r spawning anything.

In any case now it works.

In the info object I only set the "host" key (after creatig the object with
the MPI_Info_create).
I've modified my code to leave out that request and created the array of
Info object as an array of MPI_INFO_NULL but the problem is still the same.
The error is thrown only when running with more tha
ect of the
MPICH/MVAPICH?
What I have to change in order to make it run?
Or the problem is elsewhere located?
Thank you very much,
