"Invalid counter data" collected by developer panel for opencl computing application #76

Wondering if anyone has any successful experience in profiling openCL application for computing. The log file in developer panel is empty.

Hi @penglz , If there was an issue, it probably has been fixed since then as collecting counters seem to work, at least for me. Only thing is that after the capture of the profile ends, the profile has to be finalized by the developer panel before being opened in the profiler.

There is one case that I am aware of where the reported issue can occur. If the GPU buffer allocated by the driver to hold the counter data fills up, it is possible that you may see this error. If this is what is happening here, reducing the number of dispatches profiled may help.
