  • It starts with a shell code,
  • followed by the Fortran executable,
  • followed by another shell part.

1) If all goes well, the first shell part ends with:

INFO: MPI launch after 4 n second(s)
INFO: START of listing processing : Mon Aug 30 12:33:56 EDT 2021 time & date

2. Fortran part

Common error messages in this part are:

  • [warn] Epoll ADD(...) on fd n failed.  Old events were 0; read change was 0 (none); write change was 1 (add): Bad file descriptor
  • ORTE has lost communication with a remote daemon.
  • An ORTE daemon has unexpectedly failed after launch and before ...
  • An internal error has occurred in ORTE:
  • ERROR: MPI launch failed after n seconds, killing process m

If you find any of the above error messages in your model listing there was most likely a problem with the machine and you can just restart the simulation.


2) Fortran part


Jump to the end of the listings (when using 'vi', 'vim' or 'less' you can jump to the end by pressing 'G')Sometimes the model crashes so badly, that MPI is not able to gather listings from all of the processes. If this happens you can find the listings of the processes under:
