How to enable profiling for "uncached_global_load_transaction" counter in cuda command-line profiler？
回答1:
The command line profiler is controlled using the following environment variables -
COMPUTE_PROFILE: is set to either 1 or 0 (or unset) to enable or disable profiling.
COMPUTE_PROFILE_CONFIG: is used to specify a config file for enabling performance counters in the GPU and various other options.
COMPUTE_PROFILE_LOG: is set to the desired file path for profiling output.
In your case you can set above environment variables as -
COMPUTE_PROFILE=1
COMPUTE_PROFILE_CONFIG=config.txt
COMPUTE_PROFILE_LOG=profiler_output.txt
config.txt must contain an entry uncached_global_load_transaction.
