Signal 7 (Bus error)
Signal 7 (Bus error) Few days back I got a similar error, a bit of googling showed it may not be the problem of quantum espresso but may be of MPI. Contrary to that MPI forum said it could be the problem with the program but not with MPI. I somehow convinced myself that it may be due to the problem with quantum espresso because of newly installed node was giving this error. Hence, I recompiled quantum espresso on that node, to my surprise it solve the problem temporarily. Again after few days later I got the following output on my cluster. Taking the previous solution I recompiled the program, but for my surprise, I got the same error again. Digging into the cluster and checking the hard disk memory available, revealed that there was no memory left. It happens often because of not removing the memory intensive wave function files saved during previous calculations. Freeing the memory solved the problem and quantum espresso is ...
