cuda visual profiler selecting the counters

Accelerated Computing CUDA CUDA Programming and Performance

hello

in the cuda visual profiler you can select some counters like number of coalesced memory reads/writes,… but when i select these counters i can’t find it in the summary table (after clicking start ofcourse). I only see method, # calls, GPU usec, CPU usec, %GPU time. How do i make these counters appear?

Thnx
Tom

Check the bottom scroll pane, were they all 0?

Edit: You could also try checking the “Session View Settings” under the Options menu.

no i don’t have that

I also have this strange FFT error but it only happens in the profiler (all the FFT functions return cuFFTSuccess and the program works :unsure: ) and “D:/Bld/rel/gpgpu/toolkit/r2.0/cufft/src/cufft.cu” is not a valid path on my comp (BTW).

Also: when i right click on “session5” after executing and click ‘properties’ then it says ‘selected counters = none’ in the second tab :mellow: (and they are not selected anymore when i want to start a new session).

text in cuda profiler:

Read profiler output file for run #1, Number of rows=115

Read profiler output file for run #2, Number of rows=115

is it possible that my GPU can’t handle these counters i want to use?

Thnx

nvm i think i found the problem:

this is in the release notes of version 0.2 (http://developer.download.nvidia.com/compute/cuda/Profiler/0.2/CudaVisualProfiler_releases_notes_0.2_beta_windows.txt) i’m not sure if this is still the case in the version 1.1
