The nohup command will still sometimes allow the job to be killed,
for example if your X terminal crashes.  It's best to redirect stdin
at the same time, which will completely prevent bash from killing
the job.  The output goes to nohup.out.  I don't know about tcsh.

  nohup run_lapw -ec 0.001     </dev/null &

The study of non-linear physics is like the study of non-elephant biology.
