I’ve been trying to execute correctly cuda Visual profiler for 2 weeks, but i still have the famous : “Error -94 in reading profiler output. Minimum expected columns (method, gputime,cputime,occupancy) not found in profiler output file.” at the end of the tests. I have already read many topics about this problem but i did not find the solution.
the profiler does not work with my application neither with Nvidia examples.
I’ve set argument “–noprompt” and max execution time at 60 seconds.
I initialized environment variables : CUDA_PROFILE =1, CUDA_PROFILE_CSV = 1
I succeeded to create cuda_profile.log by launching application with command line ( as explained in this post : http://forums.nvidia.com/index.php?showtopic=56816 )
this file contains following informations :
method=[ _Z10init_arrayPiS_i ] gputime=[ 27.584 ] cputime=[ 5.750 ] occupancy=[ 1.000 ]
method=[ _Z10init_arrayPiS_i ] gputime=[ 26.720 ] cputime=[ 1.218 ] occupancy=[ 1.000 ]
method=[ _Z10init_arrayPiS_i ] gputime=[ 51.904 ] cputime=[ 1.723 ] occupancy=[ 1.000 ]
method=[ memcopy ] gputime=[ 11.232 ] cputime=[ 36.847 ]
I tried to put executable in the profiler directory.
during the profiling, i can see .cpj and .cvs temporary files appear but those files are deleted too quickly to be copied.
I’m using win XP32 pro with, Visual Studio Express 9 and my card is a GTX280. My CUDA Version is the 2.1 and the profiler is 1.0.11.
Is anyone in the same situation or has an idea about my problem ?
do i have to put Cuda visual profiler in a specific directory ?
thanks a lot !
