Will Java ever offer built-in support for stream processors?

[Michael Bien]

  Hello Ivan,

those interfaces for e.g. heterogeneous computing are already 
standardised and developed independently. OpenCL for example is 
standardised and maintainded by the Khronos Group. Java would never be 
able to keep up with the release cycle of the other standardisation 
entities. There was already an attempt to do that with 
OpenGL/JOGL/JSR231 but the reference implementation (aka JOGL) was 
always way ahead of the JSR. Sun even never tried to add it to the JDK 
(.. no reason to do that, it would only slow down releases).

I don't want to say its not possible but i am sceptical that there would 
be much gain to expose such fast evolving interfaces in the JDK. What 
would make perfectly sense is to do this on a much higher level and let 
the implementation make use of heterogeneous hardware - but thats when 
it starts to get really complicated :)

regards,
maintainer of jocl/jogl/joal,

michael
