CUDA 3.1 (3.0) with OpenGL - out of memory problem

Accelerated Computing CUDA CUDA Programming and Performance

Sorry if re-post but I have problem with cuda 3.1 (and 3.0) with OpenGL since I try to register the PBO but it say I run out of memory while I check the memory usage it only return half of the cuda memory has been used.
My machine has Cento OS 5.5, GTX 480 SLI-3.

I try to run the SDK example, but all the OpenGL related program have problem too. The volumeRender use only 74 MB over 1.5 G but still crash due to “out of memory”

Is that a driver issue. What should i do now. It runs perfectly with 2.3, but i need features of 3.1.

Thank

I’m having a similar problem with my application. I can register a PBO fine but in a 2nd worker thread any

new memory allocations subsequently fail. I’m using Windows XP, 7 and Vista.
