hoomd.util.cuda_profile_start()¶

Start CUDA profiling.

When using nvvp to profile CUDA kernels in hoomd jobs, you usually don’t care about all the initialization and startup. cuda_profile_start() allows you to not even record that. To use, uncheck the box “start profiling on application start” in your nvvp session configuration. Then, call cuda_profile_start() in your hoomd script when you want nvvp to start collecting information.

Example:

from hoomd import *
init.read_xml("init.xml");
# setup....
run(30000);  # warm up and auto-tune kernel block sizes
option.set_autotuner_params(enable=False);  # prevent block sizes from further autotuning
cuda_profile_start();
run(100);

hoomd.util.cuda_profile_stop()¶: Stop CUDA profiling.
