% --------------------- HYBRID PARALLEL (MPI+OpenMP) OPTIONS ---------------------%
%
% An advanced performance parameter for FVM solvers, a large-ish value should be best
% when relatively few threads per MPI rank are in use (~4). However, maximum parallelism
% is obtained with EDGE_COLORING_GROUP_SIZE=1, consider using this value only if SU2
% warns about low coloring efficiency during preprocessing (performance is usually worse).
% Setting the option to 0 disables coloring and a different strategy is used instead,
% that strategy is automatically used when the coloring efficiency is less than 0.875.
% The optimum value/strategy is case-dependent.
EDGE_COLORING_GROUP_SIZE= 512
%
% Coloring tends to perform better for the discrete adjoint than reductions because
% it uses less memory and enables the shared reading optimization for color loops.
% This option allows an automatic fallback to smaller edge color group sizes on ranks
% where the requested edge color group size is not efficient. Specifically, the largest
% edge color group size up to EDGE_COLORING_GROUP_SIZE is chosen that is at least
% 0.875 efficient. Also, this option allows using more colors, up to 255 instead of up to 64.

% Independent "threads per MPI rank" setting for LU-SGS and ILU preconditioners.
% For problems where time is spend mostly in the solution of linear systems (e.g. elasticity,
% very high CFL central schemes), AND, if the memory bandwidth of the machine is saturated
% (4 or more cores per memory channel) better performance (via a reduction in linear iterations)
% may be possible by using a smaller value than that defined by the system or in the call to
