Hello Bill Hibbard & the VisAD list,
I've noticed something unexpected when running performance evaluation
tests on our IsoSurface rendering algorithm, which is an extension of
VisAD. It seems that the run-time of our algorithm is affected by whether
or not we have the display up on the screen. That is, when we start the
algorithm running and then shrink/iconify the display, the performance
time of the algorithm improves (speeds up). For example, a 64^3
resolution isosurface is computed in about 9 seconds with the display
window down (in the task bar), and 18 seconds with the display window up
(shown). Has anyone else noticed something like this?
We're running VisAD on Red Hat Linux 7.1 with a Pentium III 730Mhz cpu and
1GB RAM.
-cheers, bob
