Title: continued to the previous post, the setting for parallel computing
Post by: luke419 on August 23, 2012, 05:35

I didn't compile it and I've used a binary file provided by quantumwise for the execution.
The commands for the execution was as follows.

mpirun -np 16 -machinefile nodefile /opt/QuantumWise/atk-12.2.2/atkpython/bin/atkpython test.py > test.log &

nodefile contains three nodes.

I've got the following result using the test script.

Master node node45

Slave node and its specific host name was not shown and it seems that something is wrong.

What should I do for it?
Can I compile the source files of ATK in my system?

Best regards,

You can't compile the source code :)

There is something wrong with your MPI setup and not ATK.

Never, ever call a Python file test.py. (It may not help in this case, but it's a general thing to note.)

Which MPI library are you using? "mpirun" indicates MPICH1 to me, or OpenMPI, you should have MPICH2.
