What is the difference between OpenCL and OpenGL's compute shader?

Question

I know OpenCL gives control of the GPU\'s memory architecture and thus allows better optimization, but, leaving this aside, can we use Compute Shaders for vector operations (add

Answer 1

Look here for another perspective. Summarizing:

Yes, OpenCL already existed, but it targets heavyweight applications (think CFD, FEM, etc), and it is much more universal than OpenGL (think beyond GPUs... Intel's Xeon Phi architecture supports >50 x86 cores).

Also, sharing buffers between OpenGL/CUDA and OpenCL is not fun.
