I suddenly realized that for my purposes, I can actually get rid of lwjgl and turn to JOCL or Aparapi's side. I want to simulate something and represent them as a pixel based picture and OpenGL is not that good for pixel drawing. I think any Java 2D graphic library will fit my needs.

That's a good news. Which I can get rid of LWJGL's OpenCL binding and turn to more object oriented apis.
