<div dir="ltr">Hello Zeke, you may also have a look at http://xconfigure.readthedocs.io/cp2k/README/. It appears to focus on CP2K/intel branch, but the recipe applies to the regular/official CP2K as well (and this is also explicitly covered). If you don't mind the outgrown ARCH file(s), you can simply copy the suggested ARCH files and proceed. There are no changes/edits needed since these ARCH files pick-up the usual environment variables (as set by the Intel development tools). Please note, there is also a list of "good compiler" as well as 2018 suite excluded from being good (at least for SMP builds). Key for correct regressions is to set the -fp-model if you also set any kind of target flag (aka -xHost or -xCORE-AVX2, etc.). The ARCH files also maintain a list of overridden builds rules for miscompiled translation units. However, the suggested 2017 compilers (u4 and later) are fairly ok (I am not even sure if they need anything to be worked around). I am only trimming these rules from time to time.

During compilation we are getting remark 8291 which states "Recommended relationship between field width 'W' and the number of fractional digits 'D' in this edit descriptor is 'W>=D+7'." Could this be causing the problem? I am attaching the error summary output by the regtest in case that would help. I would appreciate any suggestions you may have - it is very likely that we are missing something stupid that is causing the compilation trouble. Thanks so much,Zeke Piskulich</div></div></blockquote></div>
