91 PCGAMGSetSquareGraph - Square the graph, ie. compute A'*A before aggregating it
92
93 Not Collective on PC
94
95 Input Parameters:
96+ pc - the preconditioner context
97- n - PETSC_TRUE or PETSC_FALSE
98
99 Options Database Key:
100. -pc_gamg_square_graph <n,default = 1> - number of levels to square the graph on before aggregating it
101
102 Notes:
103 Squaring the graph increases the rate of coarsening (aggressive coarsening) and thereby reduces the complexity of the coarse grids, and generally results in slower solver converge rates. Reducing coarse grid complexity reduced the complexity of Galerkin coarse grid construction considerably.
