I got an error when running on the cluster. Could you please have a look if you have any ideas/experience?
I'm using version 7.1.0-patch. I have 3 nodes, each node has 20 processors. I set "n_procs:60 n_threads:1", which succeed before. But now, the simulation seems to be stuck, don't know why. From the terminal, I can see "Starting calculation", which is ok. But when I got to the result folder, there is no run_solver.log file, and of course nothing in the listing. But no error appeared. Please see the figure below.
But, interestingly, if I set "n_procs:20 n_threads:1", the simulation can run. I attached a snippet from the performance.log, where you can find the feature of the nodes.
