[Jmol-developers] multiple threads in Jmol

[Miguel <mi...@jm...>]

Egon,

I have introduced a little code into Jmol that you should be aware of.

Previously, separate threads were used in some parts of Jmol. But they
didn't have much impact on rendering performance.

A week or two ago I did some introductory work on a separate thread just
to clear the graphics buffer to the background color. Jan reported that it
didn't work very well on his Win32 systems, so I disabled it.

I subsequently reworked the code a little bit and have checked it in.

This should have no impact on single CPU systems and should offer some
improvement on multi-CPU systems.

Unfortunately, I do not have a multi-CPU system on which to test it :-(

The multi-threading behavior can still be controlled by a boolean variable
in org/jmol/g3d/Platform3D.java


Egon, do you have any ideas as to how you could verify the behavior on
your dual-CPU Sun?

(Tim, you could also play with this on your DualCPU Mac if you want.)
