    Default Java for CUDA?

    With Flash, CFD, encoding,etc getting GPU acceleration I was wondering would it be possible for Java to do so. What I mean is would it be possible for some one ( a massive Open Source project) to write a JVM that runs on a GPU? After all a GPU should be able to handle lot of the GUI(AWT/Swing stuff) and math based stuff (ie Array.sort(),etc) much faster than a CPU.
    It takes a long time to become young.

    No, it wouldnt. A graphics card can not do these things at all, it would be a lot slower actually.
    GPU's are good when doing simple floating point arithmetics which are massively parallel. Most java code is not floating point arithmetics. Especially Swing is using integers and Strings extensively. This would not go too well with a GPU. Especially since Swing uses many System calls.

    I'm not sure as to the exact problem you wish to solve with this, and as alluded to in the post above whether it will speed it up, but be that as it may have a look at JOCL

    Thread moved.

    If you describe the problem you're trying to solve, a more appropriate place in the forum may be found. Right now, it's an odd hardware question.
