Version 1.8 worked fine for me, but upgrading to 1.9, I now cannot see any information.
When I manually close my executable, I get the "Unable to gather profile data....." message
I am running on windows 7, 64 bit, Crimson driver, latest APP SDK, and HD 7700 card.
Are you trying to run GPU Performance Counters profile with any of the APP SDK sample? if so, can you please tell us which sample you are using.
Also, how long do you run the sample?
It works for the samples ( I checked the LDS sample). But, my own program hangs.
Application TImeline Trace seems to work. But not GPU performance counters.
More information: I have two modes in my program, one mode uses OpenCL events, and one does not.
The kernels are the same for both.
So, when I run GPU profiling for the mode with events, then CodeXL hangs. But, when I run the mode that doesn't use events,
it works fine.
So, it looks like the usage of events is causing this problem. I am using user events as well as runtime generated events.
