Web6 apr. 2024 · Also, nvprof is documented and also has command line help via nvprof --help. Looking at the command-line help, I see a --devices switch which appears to limit at least some functions to use only particular GPUs. You could try it with: nvprof --devices 0 --profile-child-processes python ./myscript.py WebWe'll also explain how to use nvprof to automate data collection on GPU-Accelerated systems. Demonstrations will include DOE proxy applications in arithmetic intensity, memory stride, memory coalescing, and thread divergence/prediction, all of which can be captured within the roofline methodology.
