Running the tools

Nsight Systems command-line example:

nsys profile --trace=cuda -o report-nsys-nbody /usr/local/cuda/extras/demo_suite/nbody -benchmark -numbodies=500224

Nsight Compute command-line example:

# Nsight Compute REQUIRES sudo privilleges
# Profilling integrateBodies kernel number 6 
sudo /usr/local/NVIDIA-Nsight-Compute/ncu -k integrateBodies -s 6 -c 1 -o report-ncu-nbody '/usr/local/cuda/extras/demo_suite/nbody' -benchmark -numbodies=500224

# More information - this will take a long time (5min) for a single kernel
sudo /usr/local/NVIDIA-Nsight-Compute/ncu -k integrateBodies -s 6 -c 1 -o report-ncu-nbody \
