Hi all,
After all my days of struggle with the Floating Point Exception error, I
finally decided to uninstall my Aspect (1.4.0-pre) and start over.
Now I installed Aspect 1.3 , from scratch. This version, being older, I
guess is better supported and better known by you guys.
Eureka !
I managed to successfully run Aspect on TACC Stempede cluster, for my
very first time. No errors of FPE or graphics.
I run the 3D convection example. At least it produced the initial
picture right, and it is time-stepping.. Unfortunately I run out of time on
the queue, so I will put my stuff to work on a larger queue.
That is all for now. I will come back hopefully just for more advanced
questions.
I greatly appreciate your attention, thanks,
cheers,
Felipe
