(2014), 74, pp. 3176. Link (CTF) as a computational back-end. To switch on the use of CTF, use the CC_BACKEND keyword. In addition, Q-Chem should be invoked with the -np nproc command line option to specify the number of processors for a distributed calculation as nproc. Consult Section 2.2.1.1 for more details about running Q-Chem in parallel.

Note:  This option is not yet available in public release.
