I can replicate that problem here on both 14.11.9 and 14.03.11, and the manual
page is pretty clear that SLURM_NTASKS should be 7 for this case.
--ntasks-per-node=<ntasks>
Request that ntasks be invoked on each node. If used with the
--ntasks option, the --ntasks option will take precedence and
the --ntasks-per-node will be treated as a maximum count of
tasks per node. Meant to be used with the --nodes option.
Well spotted!
All the best,
Chris
