PCGASMType

Type of generalized additive Schwarz method to use (differs from ASM in allowing multiple processors per domain)

Synopsis

typedef enum {PC_GASM_BASIC = 3,PC_GASM_RESTRICT = 1,PC_GASM_INTERPOLATE = 2,PC_GASM_NONE = 0} PCGASMType;
 PC_GASM_BASIC - symmetric version where residuals from the ghost points are used
                and computed values in ghost regions are added together. Classical
                standard additive Schwarz
 PC_GASM_RESTRICT - residuals from ghost points are used but computed values in ghost
                   region are discarded. Default
 PC_GASM_INTERPOLATE - residuals from ghost points are not used, computed values in ghost
                      region are added back in
 PC_GASM_NONE - ghost point residuals are not used, computed ghost values are discarded
               not very good.
