Tracing with rocprof

In this exercise your task is to trace execution of streams/02-concurrency exercise solution.

Rocprof can be used to trace HIP API calls, among others, with option

> rocprof --hip-trace <executable>

It will output a file named results.json which may be visualized for example with perfetto trace visualizer (https://ui.perfetto.dev/) or chrome/chromium built in visualizer tools (type chrome://tracing/ in the URL field).

Exercise

  • Trace the HIP API calls of the streams.cpp code and visualize the results.
  • Modify WORK preprocessor macro to so large that kernel executions begin to exceed memory transfers.
  • Does the kernel execution order correspond to their stream numbering?
