Yes you are right this is what it says but if fact the weird thing is that not all times the error message appears….I send to 20 nodes and only one gives this message, is this normal…

Yes - that is precisely the behavior you should see if there is a race condition, for example, that causes a process to exit without calling finalize.

You should always only get one such message as we kill the remaining processes as soon as the error occurs.

Well, as it says, your processes called MPI_Init, but at least one of them exited without calling MPI_Finalize. That violates the MPI rules and we therefore terminate the remaining processes.

Check your code and see how/why you are doing that - you probably have a code path whereby a process exits without calling finalize.

Hi all

I get this error when I run a paralelized python code in a cluster, could anyone give me an idea of what is happening? I'am new in this Thanks...

mpirun has exited due to process rank 2 with PID 10259 on
node f01 exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Thanks!!
