Detailed Description

template<typename PhaseChangeRegistrars>
struct PhaseControl::Actions::ExecutePhaseChange< PhaseChangeRegistrars >

Check if any triggers are activated, and perform phase changes as needed.

This action is intended to be executed on every component that repeatedly runs iterable actions that would need to halt during a phase change. This action sends data to the Main chare via a reduction.

This action iterates over the Tags::PhaseChangeAndTriggers, sending reduction data for the phase decision for each triggered PhaseChange, then halts the algorithm execution so that the Main chare can make a phase decision if any were triggered.

Uses:

• GlobalCache: Tags::PhaseChangeAndTriggers
• DataBox: As specified by the PhaseChange option-created objects.
  • PhaseChange objects are permitted to perform mutations on the DataBox to store persistent state information.
