Dear Fernan

I cannot reproduce that error with your input files using the current cp2k trunk (nor the 6.1 release) version. You are possibly using a miscompiled cp2k executable.

Subject: [CP2K:11228] error: sum of local cols not equal global cols

Dear all,
I am trying to run a geometry optimization of a unit cell of MoS2 with CP2k compiled with gcc on my desktop. Please see input script files. The problem that I face is that cp2k aborts the simulation with the following error: 'sum of local cols not equal global cols'. The last lines of the log.out file look like:

I have extensively used cp2k and I usually modify little my input script files for each system, including the main one (mos2.inp) for this case, so I suspect that the error cannot reside on the DFT parameters I employ. However, this is the first time I face this error. Furthermore, if I run this script with a version of CP2k compiler with Intel on a cluster, I get a segmentation fault of the type: forrtl: severe (174): SIGSEGV, segmentation fault occurred.

I would really appreciate any help.
