Parallel Manager. More...

Detailed Description

Parallel Manager.

This class sets and manages thread / teams levels, scratch memory sizes, and kernel executions. ex: Compadre::ConvertLayoutLeftToRight clr; Compadre::ParallelManager pm; // no tag specified pm.CallFunctorWithTeamThreads(clr, 100, "MyFunctorName"); // some tag specified pm.CallFunctorWithTeamThreads<DefaultTag>(clr, 100);
