◆ gs_init()

subroutine gather_scatter::gs_init ( class(gs_t), intent(inout)  gs,
type(dofmap_t), intent(inout), target  dofmap,

◆ gs_init_mapping()

subroutine gather_scatter::gs_init_mapping ( type(gs_t), intent(inout), target  gs)
private
Note
this might be a bit overkill, but having many collisions makes the init take too long.
