penmpi. I could understand the problem as you said in
the reply. But how can I set different buffers for them?
thank you

Hello,
I am looking for MPI tests, that tests performance, not just basic features.
What kind of tests can I add to MTT (OpenMPI testing tool)?
Where can I find open source tests to test OpenMPI performance?
Any information you can provide will be helpful.
Thanks!

buffer pointer, error stack:
PMPI_Allgather(958): MPI_Allgather(sbuf=0x6465d30, scount=1,
MPI_INTEGER, rbuf=0x6465d30, rcount=1, MPI_INTEGER, MPI_COMM_WORLD)
failed
PMPI_Allgather(931): Buffers must not be aliased
Thank you very much

difference between these three options?
Any help would be greatly appreciated.

I did a simple test by creating a shared library using a FORTRAN
code and the update made to the common block is taken in to account by the
executable. Is there any flag or pragma that need to be activated for mixed
language MPI?
Thank you once again for the reply.

common blocks. As I access those
common blocks during runtime the values are not initialized. I would like
to know if what I am doing is possible ?I hope that my problem is
clear..
Your valuable suggestions are welcome !!!
Thank you,
Rajesh
As a followup to my problem, I tested this sample code with LAM/MPI and it
worked perfectly without any segmentation faults. Has any one tried this
and faced this isue? Any help will be appreciated.

Hi,
I am trying to write a simple code which does the following -
A master process running on 'n' processors spawn 4 processes using the
MPI_Comm_spawn_multiple command. After spawning, the intercommunicator
between the master and the spawned processes are merged using
MPI_Intercomm_merge to create
during MPI_Init call. But
is there a way to update the value of MPI_COMM_WORLD at runtime
to reflect this expanded set of processes? Is it possible to some how
reinitialize MPI_COMM_WORLD using ompi_comm_init() function?
Regards,
Rajesh
