<div dir="ltr">Hi Kwon, Sorry, but your post isn't understandable - so I guess what your questions are. Your benchmark results are correct and, depending on the hardware behind, also the timings look reasonable. From the header of a calculation-output one can extract all important data about the version, compile time, .... See: <pre> CP2K| version string: CP2K version 2.6.2 CP2K| source code revision number: svn:15893 CP2K| is freely available from http://www.cp2k.org/ CP2K| Program compiled at Fri Apr 1 10:17:36 KST 2016 CP2K| Program compiled on eagle CP2K| Program compiled for Linux-x86-64-intel</pre> Please go on now with a full regression test to ensure numerical correctness for all tests - the steps are described in the link of my last post. If you are unsure on how to interpret the results, just attach the regression-test output in your next post. Best regards, Andreas </div>
