Hi Dorian,
thank you for your message.

This looks like a question for the MPICH2 developers.
Specifically, it looks like you are using MPICH2, not Open MPI. They
are entirely different software packages maintained by different
people -- we're not really qualified to answer questions about
MPICH2. The top-level API is the same
In the example you cite below, it looks like you're mixing MPI_Gather
and MPI_Send.
MPI_Gather is a "collective" routine; it must be called by all
processes in the communicator. All processes will send a buffer/
message to the root; only the root process will receive all the
buffers/messa

Hi,thanks for your reply. let's say i have 3 processors. I sent msg from
1st,2nd processors and want to gather in processor 0 processor. so i tried
like following. it couldn't receive msg sent from processor 1 and 2.

Yes of course. Can you send a short example of what doesn't work? The
example should presumably be less than about 20 line

To make sure you don't use any "leftover" from another system install
when upgrading, you should specify --enable-prefix-by-default when
configuring the source tree for compilation. This will always select
the binaries and libs that are part of the mpirun you are using.

You are using MPICH. You should ask submit your question to their
mailing list to get the most accurate answers. From the log you
provide, I can still guess that you need to define a machinefile
containing at least 4 computing ressources. If you need more details
concerning machinefiles in
