Dear users, just a reminder in case you run parallel calculations with ATK 2014.
As specified in the release letter (http://quantumwise.com/publications/quantumwise-news/item/827-vnl-atk-2014-released):
you now need to set OMP_NUM_THREADS=1 if you place several MPI processes on the same node, else parallel performance degrades substantially.
