[CP2K-user] [CP2K:17807] Memory Leak on CP2k 9.1

[Krack Matthias (PSI)]

Hi Quentin

It seems that you are using OpenMPI which is known to have leaks in some versions. Check this issue<https://github.com/cp2k/cp2k/issues/1830#issuecomment-1012561166> and this discussion<https://groups.google.com/g/cp2k/c/BJ9c21ey0Ls/m/2UDxnhBRAQAJ> here on this forum for further information.

Subject: [CP2K:17807] Memory Leak on CP2k 9.1

Dear all,
Our group is encountering a memory leak issue that makes running DFT-MD impossible with large systems (~100 atoms) on one of the clusters we have access to, even though the same calculations run correctly on other machines.
The cluster support sent me the following valgrind output and asked me to find suggestions on how to proceed. Does anyone have input on how to deal with such memory leaks ?
Best,
Quentin P.
