I am comparing the pre-compiled binary, cp2k-4.1-Linux-x86_64.ssmp with a
version that was compiled with Intel 2015 compiler. The pre-compiled one
seems to take 3-4X as long per iteration. I did the whole export
OMP_NUM_THREADS and a top does show the cpu usage go to 1600% ( the machine
has 16 cpus ).
Is it a known issue that the pre-compiled binary will be this much slower?
Or is there likely something else going on?
