Charm++ chare array for distributed flux-corrected transport.


Charm++ chare array for asynchronous distributed flux-corrected transport (FCT).

There are a potentially large number of DistFCT Charm++ chares created by Transporter. Each DistFCT gets a chunk of the full load (part of the mesh) and performs flux-corrected transport.

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/
