Additional data. I reverted my driver version in Windows 10 device manager. nvidia-smi shows driver 442.23 and cuda version 10.2. With Nsight Systems 2020.2 I observe I can get CPU details, but no GPU details. Error in Nsight Systems is "
Incompatible CUDA driver version. Please try updating the CUDA driver or use more recent profiler version."
Found advanced search that shows historical geforce game ready driver releases, but the descriptions don’t show the corresponding CUDA version of each driver. SMH. Couldn’t find a table anywhere that shows CUDA versions for each driver release.
Attempted to reinstall CUDA 10.2, which appeared that it should reinstall driver and nvidia cuda tools to specific versions, which should therefore all be compatible. I didn’t catch the exact driver version it was going to install, but noted that it was earlier than 442.23. After CUDA installation, found that nvidia-smi still shows 442.23, so I presume that the CUDA install chose not to install an earlier version of the driver.
CUDA 10.2 installed Nsight Systems 2019.5.2. With this version and driver 442.23, I can get GPU memory usage, but do not have any info on GPU kernels. I do see NVTX annotations however. Nsight Systems error is “Incompatible CUDA driver version. Please try updating the CUDA driver or use more recent profiler version.”
