HPC/Applications/atk

Co-loading ATK and VASP modules

This module needs MPICH2 libraries (happily provided by Intel-MPI), and hence clashes with VASP, which uses HPC/Applications/openmpi.

Co-existence is possible as follows:

module unload openmpi
module load atk
module load openmpi
…
module load vasp5      # … or other versions

• See QuantumWise's Parallel Guide

Local changes

• We use Intel-MPI instead of MPICH2, with the Hydra process manager instead of MPD. See the sample.job file for details:

Remote access from Windows

1. Install ATK on your machine.

   2. Advanced: Set up license forwarding using Cygwin.
3. Configure ATK to use forwarded licenses.

To connect:

1. Follow section Connecting to reach clogin.
