I am  trying to run:
mpirun -np 2 siesta < input.fdf > output.out

I always got the following error message

[minodo01:9113] *** An error occurred in MPI_Comm_group
[minodo01:9113] *** on communicator MPI_COMM_WORLD
[minodo01:9113] *** MPI_ERR_COMM: invalid communicator

--------------------------------------------------------------------------
mpirun has exited due to process rank 1 with PID 9114 on
node minodo01 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

help / error messages


But when I check the output file, I can get the following lines at the end:
...
* Maximum dynamic memory allocated =     20 MB

It stopped suddengly

So, the calculation started normally, but ...  I dit it on a single machine 
with 2 cores. Do you have any idea about it, please?

I saw this problem on page 
http://www.mail-archive.com/[email protected]/msg03768.html but I cant 
understand how can I fix it

Thank for any help!!!!
