Sorry, my OpenCL knowledge is still not good enough to give you an answer
here in the way 'this can't work because ..' - or, 'this is great and matches
the architecture.'. I just helped out with the native bindings and
general knowledge a bit.
I am afraid I will tell you the same things here as I did
in our JOAL conversation (patching / unit tests / maintenance),
if you get the idea :)
Since we try to get in some mobile OpenCL 1.1 device for our BOF this year,
I probably have to make a crash course into the current code base.
In May I will have the privileged of 3 weeks 'off',
which means I will have time for this endeavor.
I like to validate whether the current JOCL can be matched to
the OpenCL C++ Wrapper API, if this is not done yet .. etc.
Since you are at least interested, I welcome your support of course.
However, whoever likes to help and support (any project on jogamp)
would need to get familiar w/ the toolchain we use (git, ant, ..).
Otherwise the real maintenance work would become unbearable.
But discussions and knowledge exchange are very valuable contributions
as well, which don't require those things :)
Well, let's see how it goes.
