Debugging is not a straightforward task. Even posting the code doesn't
necessarily help (since no one may be motivated to help or they can't
reproduce the problem or...). You'll just have to try different things
and see what works for you. Another option is to trace the MPI calls.

A) Post only the relevant sections of the code. If you have syntax
error, it should be in the Send and Receive calls, or one of the lines
where the data is copied or read from the array/buffer/whatever that
you're sending or receiving.
B) Try reproducing your problem in a toy program

Do you have better ideas ?
Any help is appreciated.

I should have checked ompi_info myself.
The FAQ on the website should probably be updated to reflect this

Thanks, I have used "cout" in c++ to print the values of data.
The sender sends correct data to correct receiver.
But, receiver gets wrong data from correct sender.
why ?
thanks

Here's the patch :)

Hi,
In my Open MPI program, one master sends data to 3 workers.
Two workers can receive their data.
But, the third worker can not get their data.
Before sending data, the master sends a head information to each worker
receiver so that each worker knows what the following data package is.
Looks like there's something specific to your machine. Can you send the
XML output of lstopo ?
thanks
