% 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).

% 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
