Hello, good day:
I have two questions.
1.-The specifications of the computer you recently installed QE, says:Processor: 6-Core Intel Xeon E5Cores number: 6
Mi question is: in the .out file says: Parallel version (MPI & OpenMP), running on      12 processor cores     Number of MPI processes:                 1     Threads/MPI process:                    12
I do not understand why recognizes 12 cores?, and is running on all cores or just one?
2.- The second question is: I change the ecutwfc=100.D0, ecutrho=400.D0, Run the .in file and one file with name CRASH containing the following:
  task #         0   from diropn : error #        10     error opening /Users/sqs-ciacyt/espresso-5.1/tempdir/CO.wfc1
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.You may or may not see output from other processes, depending onexactly when Open MPI kills them.--------------------------------------------------------------------------




with ecutwfc< 100.D0 I do not have that problem.
Thanks an sorry for the inconvenience.
Best Regards.
