[ramkrishna]

Dear Sir,
     Is it possible to run a ATK job in Batch Queue in Clusters?? If so, then please let me know how to do that ??

Thanks

Yes it is.

What cluster queue system do you have?

[ramkrishna]

The cluster queue system is pbs moab.

Thanks

Dear Sir,
     It will be very much helpful, if you let me know, how to set up the batch queue.

Thanks

This is not really an ATK question. To run ATK in parallel via a queue, all you need is to write

mpiexec -n 4 atkpython script.py

or similar at the end of your PBS script. Setting up the whole PBS system, however, is a sysadm task, and you can find instructions about it all over the internet.

For some further tips, see http://quantumwise.com/documents/tutorials/latest/ParallelGuide/index.html/

Dear Sir,
      I was looking for the possibility of using MPI in the link as you have given earlier. It is mentioned that  "To parallelize an ATK calculation over the cores of a dual- or quad-core computer using OpenMP requires no additional licenses. Using MPI, on the other hand, does." Currently we have a active master- slave license, so will that be sufficient to run MPI or is there any separate license for MPI that we have to purchase??

Thanks

The ATKSlave features are what you need to run in MPI.
