Please provide more details about the issue. Which GPU/OS/Driver etc are you using?
Also please provide a test case (or details if you are running SDK samples) if possible. |
GPU: HD4870, OS: Vista x86 SP2 business ed., Driver: 9.12 hotfix (ATI GPU 0: ATI Radeon HD 4700/4800 (RV740/RV770) (CAL version 1.4.519, 512MB, 1200 GFLOPS peak))
About test case, it would be hard to do it seems. I use OpenCL/Brook+ mixed app.
It works OK now at some smaller memory allocation. And it worked OK with bigger memory allocation when there were no another GPU-based apps running.
That is, maybe not heavy load per se involved, but memory allocation.
In both cases buffer allocations didn't fail though, no error codes returned.
It seems like runtime silently takes already allocated memory part for another needs then return it to app... but with wrong data.
