Hello everyone. Recently I started looking into cooperation between PyCUDA and OpenGL. It works (I am getting segfaults at the end of my program but I might not be cleaning some object properly).
During reading documentation and looking at PyCUDA sources I noticed that PyCUDA uses pycuda.gl.BufferObject, which uses cudaGLMapBufferObject, cudaGLRegisterBufferObject, and cudaGLUnregisterBufferObject. They are described as depreciated in NVIDIA CUDA reference and programming guide. I would like to try to switch PyCUDA to using cudaGraphicsResource (and other functions from this family) if noone is already doing this. Questions: 1. Is is possible to do this for 0.94, or should I wait for 0.95? 2. Should I try to change existing classes (BufferObject) or create new ones, and existing ones will be tagged "depreciated"? Two possible problems for now: 1. I only have NVIDIA 9400M (NVIDIA ION) GPU with capabilities 1.1. I would like to buy Fermi device (GTX460?) but it will not be possible in this month. 2. Debian has 195.x drivers and CUDA 3.1 does not work well with those drivers. There is plan to get 256.x drivers, but because of Debian freeze it will not be fast. Now focus is on polishing existing driver packages and on supporting legacy hardware.
