Thank you for your suggestion. It was successfully parallelized. Thank you again.

I solve this problem by handling the queueing system.

General Questions and Answers / Parallelization with MPICH2
« on: February 10, 2014, 01:31 »
Dear ATK staff members,
I'm using the demo version of ATK (13.8.0) and installed on the Linux (CentOS 5.
.
I want to calculate with several nodes (8cpu per 1 node) total 4 nodes.
In the manual,
To run ATK on 4 nodes:
mpiexec -n 4 $ATK_BIN_DIR/atkpython script.py > script.log
with this command, the job just running in the single node. (not equally distributed!)
node1 (4 process running)
node2 (not running)
node3 (not running)
node4 (not running)
I found the manual of the Guide to running in parallel.
In order to run the MPI processes are distributed equally among the nodes, using the -npernode option. However, the option is not supported in the MPICH2. I checked for several versions as 1.0.5p4, 1.2.1p1, 1.4, 1.5.
The demo version does not support the parallelization?
