[CP2K-user] About energy change for the AIMD equlibration process

[Shuai Jiang]

Dear all,

I tried to run the H2O-32.inp in the tests/QS/benchmark folder after 
installing CP2K6.1 in the CentOS. And the figure within 250fs or so shows 
the energy increases, which I think this may be called "drift". I think 
this energy drift should not happen as the clusters have been equilibrated 
under the TIP5P force fileld. I have looked it up in the google group and 
found maybe it is due to the intel 
compiler(https://groups.google.com/forum/#!msg/cp2k/A2Rf79443D4/wjYK6lBbAQAJ). 
So I tried reinstall the CP2K (5.1, 6.1, 7.0) as well as reinstall 
different Intel compilers (Intel 2014, 2019). Even after all those trials, 
I could still see the energy drift, could anyone tell me what's wrong? 
Thanks a lot.
