Question

如何啓用CUDA中的命令行仿形「uncached_global_load_transaction」計數器分析

Answer 1

命令行分析器是使用以下環境變量來控制 -

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. 

你的情況，你可以設置上述環境變量作爲 -

COMPUTE_PROFILE=1 
COMPUTE_PROFILE_CONFIG=config.txt 
COMPUTE_PROFILE_LOG=profiler_output.txt 

config.txt必須包含一個條目uncached_global_load_transaction。
