src/Inciter/DiagCG.hpp file

DiagCG for a PDE system with continuous Galerkin without a matrix.

There are a potentially large number of DiagCG Charm++ chares created by Transporter. Each DiagCG gets a chunk of the full load (part of the mesh) and does the same: initializes and advances a number of PDE systems in time.

The implementation uses the Charm++ runtime system and is fully asynchronous, overlapping computation and communication. The algorithm utilizes the structured dagger (SDAG) Charm++ functionality. The high-level overview of the algorithm structure and how it interfaces with Charm++ is discussed in the Charm++ interface file src/Inciter/diagcg.ci.
