Can someone who knows more explain how java will do gpgpu? Is it going to make the jvm runnable on a gpu, or are they going to do something like compiling jvm byte-code to C/++/assembler code that will handle all the memory management it takes to run code on the gpu?
They could always do some fancy operating overloading to produce expression trees that are then converted into GPU codelike I did in this C# library I made a while ago (basically, call it a staged embedded DSL):
