MULTIPHASED PROFILE GUIDED OPTIMIZATION

摘要

Multiphased profile guided optimization optimizes executable code based on data collected during multiple training runs of a training executable. In multiphased profile guided optimization, multiple sets of profiling data are collected where each set of profiling data is associated with a program phase and a particular training run. Program phases include but are not limited to different program features, startup, steady state and shutdown. The program features can run concurrently. Priority of the phases can be specified.

主权项

1. A system comprising:
at least one processor: a memory connected to the at least one processor; and at least one program module comprising a multiphased profile guided compiler that receives profiling data associated with a plurality of program phases and generates an optimized executable based on the profiling data, the optimized executable optimized for a program phase of the plurality of program phases.
