<p><font face="serif">Guys -- with recent changes to encryption
standards I found out today that I've got to rewrite and test my
perl scripts that help you generate ssh keys for the cluster.
I've got to think how to do this carefully so I don't impact my
research calculations that are currently running on the
cluster. I won't get that done tonight. As such tomorrow is
going to be a "work day" to work on code. I will be in the lab
at 9:30 if you have any questions. If you are not planning on
coming to class please let me know. </font></p>
<p><font face="serif">Remember, you need to use the lab computers to
test your code because they will give you consistent results
(not NaN) for the trace and idcheck with MAXDIM=100.</font></p>
<p><font face="serif">Here are results for an early, non-optimal C
program, the original Dusty, my modern Fortran dusty, and a
modern Fortran dusty on which I did some major code
rearrangement based on ideas from the handouts I gave you last
week. MAXDIM in all cases was 100.</font></p>
