We don’t have experience yet with exactly that version (ifort 17.0.1), but with the 17.0.0 compiler we find that a couple of files need to be built at reduced optimisation level - see https://dashboard.cp2k.org/archive/epcc-phi-psmp/rev_17693.txt for an example arch file which is working.
Were you able to run the CP2K regression tests with success?
