Cublas, cuda and OpenGL VBO

Accelerated Computing CUDA CUDA Programming and Performance

I have an array of float data that I read from in my kernel and that I want to use as a vector with cublas. After some manipulations this vector contains data that I could use as positions for my OpenGL rendering. I’ve seen the examples of using the VBO.

My question(s):

  1. Can I combine the cuda/VBO combination of a float array with cublas. (So that I don’t have to copy data)?

  2. Are there any potential (performance) problems with this?

Thanks in advance
Bart.
