profiler not logging memcopies under 2.1?

Accelerated Computing CUDA CUDA Programming and Performance

Hi all,

I just moved to CUDA 2.1 and now when I profile my app, the profiler does not log the memcopy routines in the output file. I’ve tried running from the command line and tried using the visual profiler (v1.1.08) under windows. In neither case does the .csv log file contain any entries for the memcopies. Everything worked fine under CUDA 2.0 (visual profiler version).

Anyone else solve this problem?

Cheers,
David

more info on my environment/system:

OS: WinXP Pro SP3

CUDA Version: 2.1

CUDA SDK Version: 2.1

Visual Profiler: 1.1.08

Compiler: Visual C++ 2008 Express

GPU: GTX260 (216 core version)

Driver: 181.20

Anyone getting profile data with memcopies in them? I’m trying to figure out the best way to schedule the copies with kernel launches and am really trying to understand if my async memcopies are actually asynch!!!

Please help!!!

Thanks,

David
