by · Sep 9, 2017 · 309 views ·

In this talk I will present an overview of the trace-based performance evaluation tools for PPC. This includes trace collection with valgrind itrace, the sim_ppc timing simulator, the pipestat tool for analyzing instruction traces and timing simulator event traces, and the timing simulator event trace viewer tools. I will describe how to use these tools to identify user and library code issues as well places where the compiler generates sub-optimal code.
