#for C++ and python code, all need to repacle Opencl library
after run pip3 wheel ., the profile Opencl library is at ./bin/intercept/
for windows python, can put the OpenCL.dll in same direcotry with the python.exe
for LINUX, can export LD_PRELOAD=./bin/intercept/libOpencl.so

# windows
set CLI_ChromePerformanceTiming=1
set CLI_DumpDir=C:\trace_dir
set CLI_ChromePerformanceTimingPerKernel=0
# linux
export CLI_ChromePerformanceTiming=1
export CLI_DumpDir=/your_trace_dir
export CLI_ChromePerformanceTimingPerKernel=0
# open the trace file with chrome in mode chrome://tracing
