Hi Michael,
I deleted the original message on nabble forgetting this is a mailing
list ... The crashes were all down to some rather embarrassing (mis)use
of Buffer objects and a few pokes later I got my stuff to run. My
patience had prematurely run out it seems ...
no problem. good that it works for you. nice.
No crashes anymore, but the Mandelbrot isn't really working still -
colourmap seems to be off, and usually all black.
are we now talking about this demo?
http://github.com/mbien/jocl-demos/blob/master/src/com/jogamp/opencl/demos/fractal/MultiDeviceFractal.java
it works on all systems and drivers i tried so far. Maybe its a
pixelformat issue or so (it uses GL-CL interoperability).
So it might just be a java-side issue. I've made a bit
of a pigs breakfast of the source, but if you would find it useful I
can probably clean it up a bit to make another `hello world' example
(if you don't have it converted already).
we have already a fractal demo (mentioned above). But sure
contributions are always welcome. If you find somewhere a cool demo to
convert... sure (e.g i converted the julia3d demo from c to java). But
please check the license, jogamp projects are all BSD.
Thanks for the other info, not using jogl yet but will eventually.

could you provide a testcase so I could try to reproduce the crashes?
Small as possible so we can add it to the unit tests... would be cool.
if you are using JOGL:
please call GLProfile.initSingleton() before doing any UI work. This
changed recently to enable some threading optimizations. We try to get
rid of this workaround somehow.
