I am working remotely on some CUDA program in the Linux environment. Since there are problems with X-forwarding, I cannot use CUDA Visual Profiler and have to use CUDA Command Line profiler instead.

The problem is, it doesn’t recognize some basic counters I want it to follow. E.g running the program with the following command

COMPUTE_PROFILE=1 COMPUTE_PROFILE_CSV=0 COMPUTE_PROFILE_LOG=log  \
CUDA_PROFILE_CONFIG=Config.txt ./my_program

With the Config.txt file being:

warp_serialize
shared_replay_overhead

Results in the following log:

NV_Warning: Ignoring the invalid profiler config option: warp_serialize
NV_Warning: Ignoring the invalid profiler config option: shared_replay_overhead
CUDA_PROFILE_LOG_VERSION 2.0
CUDA_DEVICE 0 GeForce GTX 580
CUDA_CONTEXT 1
TIMESTAMPFACTOR fffff6c8b2653dd8

…

My enviroment specifications:

Card: GeForce GTX 580
CUDA Driver Version / Runtime Version:          4.1 / 4.1
CUDA Capability Major/Minor version number:    2.0

Any ideas what I might be doing wrong?

    The warp_serialize counter is not supported for devices of compute capability 2.x. See Table 6. Profiler Counter Types at Compute Visual Profiler User guide.

    Regarding to the shared_replay_overhead I have not found anything related to it.
