I am not certain, but I believe 68 GB should be enough memory.

```
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

mpirun noticed that process rank 7 with PID 0 on node ip-10-21-154-88 exited on 
signal 9 (Killed).

```

Look at the “ancillary” log file from processor 7, which should have a name beginning with CTM\_LOG\_007. Is there an error message?

Please see [this post](https://forum.cmascenter.org/t/please-read-before-posting/1321) (and the Debug Tutorial) for ideas on how to debug this issue.
