Is it possible to do GPU programming in Java ? I mean without using native libraries.
And how much of a performance improvement can one expect when we switch over to gpu's ?
Edit:
I am not looking at game programming, I want to do hard core number crunching.
If you are still considering hard core number crunching in Java on GPU without using native libraries, you might be interested by this blog article http://ateji.blogspot.com/2011/02/java-on-gpu-with-ateji-px.html We (I am part of the Ateji team) have seen performance of up to 60x so far on Java applications that can be massively parallelized.
