Hi,
I've been trying to instrument an OpenCL application today to get in-application profiling. The application can be profiled without problems using CodeXL. However, when I try to use the GPUPerfAPI, I get a bluescreen. More specifically:
All API calls returns success. The application is not started as elevated; starting it with administrator rights also results in a bluescreen. Is there some minimal example how to use the PerfAPI for OpenCL?
Solved! Go to Solution.
Hi,
The system crash/bluescreen appears to be a regression introduced in the Catalyst 14.4 release. It affects gathering performance counter data for any OpenCL application on any Southern Islands device. We recommend not using this driver release with CodeXL if you have a Southern Islands device.
Thanks,

Thanks, I'll give it a shot on a R9 290X as soon as possible. I was surprised that it works just fine using CodeXL but fails using the PerfAPI.
Works on a R9 290X, thanks!
