Implementation and Optimization of a CFD Solver Using Overlapped Meshes on Multiple MIC Coprocessors

Listing 1

: Procedure of solving equation (1) on overlapped mesh system.

(1)	Conduct mesh assembly to obtain interpolation information over the mesh system (MS)
(2)	Read flow configuration file and overlapped mesh data
(3)	Initialization
(4)	repeat
(5)	for each iblock in MS do
(6)	Apply boundary conditions to iblock
(7)	end for
(8)	: exchange interpolated data between overlapped block pair , where CRI: cells receiving interpolation data and CPI: cells providing interpolation data
(9)	and : exchange each one-to-one block data at block interface connecting and
(10)	for each iblock in do
(11)	Calculate , , and fluxes on iblock
(12)	AF time advancement and update solutions on iblock
(13)	end for
(14)	Until convergence
(15)	Output flow data
