I suppose you're running on a parallel machine with MPI. If this is the case, I think that the delay after which the stdout is available depends on the specific MPI implementation and/or on how the machine is configured. Anyway, during execution you may have access to the allocated nodes and at least check if the code is running (using top command for instance). > information is updated from time to time during the calculation.

Does anyone here encounter If it is an occasional situation and it cannot be reproduced, it is probably due to a temporary failure of one of the nodes on which the job was running. It may be caused by many things, you should look at stderr and stdout of the job for error messages from the operating system/compiler/libraries/... You may find that it has been caused by disk failures/too much memory required/network communication problems/... These are not related to QE and cannot be solved by the users of this forum. If you have evidence that the problem persists, please provide a (possibly small) sample input and output files Regards GS problem before, any suggestions to solve this problem ?
