<div dir="ltr">Dear all, My name is Fabio and I am having problems installing CP2K on the new Santos Dumont Brazilian cluster, that has Intel Xeon E5-2695v2 processors (http://sdumont.lncc.br/machine.php?pg=machine#). I am not an expert in this topic but I have successfully installed CP2K in several different architectures, with both gfortran and intel compilers. Since I am not a superuser in this cluster I don't have access to the nodes, I can't "ssh" them, so I am not sure what is going on and maybe somebody here can help me. Below you can find the last makefile I tried (I have several). It is the simplest one I could make. The installation always goes smooth, without any errors. But during runtime the code stops writing anything in the output after 1-2hours, not even error messages. The input used is attached to this e-mail, but all inputs I've tried so far have failed, and they have all been successfully run in other clusters/machines. Wave functions are not updated, but the code keeps running and the job is not killed. The administrators from the cluster told me that the nodes still have "Nproc" cp2k processes running during the whole time the job lives, even after it stops updating the outputs. I have searched for similar issues in the forum and they gave me the idea of reducing the number of processors or/and reducing the optimization level, using -O1/O0 flags. But even after trying this the problem still happens, not after 1-2hours but after, say, 8 hours. It depends a lot on the system/makefile used. Does someone have any tips on what is going on, what could be tried, or what flag to use so I can collect more information during runtime that might help elucidating the problem!? Thanks very much for your time and all the best!
