Hi All,
Thanks a lot for your support. It was a big help. I found a race condition
in my code and now the problem is solved.
Regards,

I was getting the same error a few weeks ago. In my case the error
message was spot on. I was trying to put too much data in a buffer using
MPI_Pack.
I was able to track down the problem using valgrind. Have you tried that
yet? You need to install valgrind first and then compile OpenMPI with
valgr
Yes but only one thread at each client is allowed to use MPI. Also, there is
a semaphore on the MPI usage.

I'm using blocking Send and Receive. All the clients are sending data and
the server is receive the messages from the clients with MPI_ANY_SOURCE as
the sender. Do you think there is a race condition near this pattern?
I searched a lot and used totalview but I couldn't
We've seen similar things in our code. In our case it is probably due to a
race condition. Try running the segv'ing process in a debugger, and it will
likely show you a bug in your code

Hi All,
I'm facing a strange problem with OpenMPI.
I'm developing an application which is required to send a message from each
client (1 MB each) to a server node for around 10 times per second (it's a
distributed render application and I'm trying to reach a higher frame rate
). The problem is t
