Question: JCuda integration

[davidpham87]

Hello,

Thanks a lot for the library.

I wondered if you think one could integrate JCuda (https://github.com/jcuda/jcuda-main) in your java API? From my understanding, the device variables should be interchangeable between ThrustRTC and JCuda?

For the context, I am interesting to use ThurstRTC Java API from Clojure.

Best regards,
David

Hi,
I've just added some new interfaces to the JAVA API:

• long DVVector.native_pointer():
  You can use this to retrieve a native CUDA pointer from a DVVector object

• class DVVectorAdaptor:
  You can use a native CUDA pointer from an external library to initialize a DVVectorAdaptor object, then use it similarity as a DVVector object.

Theoretically these 2 interfaces should enable the interoperation with jcuda. Basically, you get a native pointer from one library, then pass it to the other library to initialize an object in the 2nd library, by I haven't got a chance to try it yet.

Looks like getting a native pointer from jcuda is a little bit tricky:
