First thanks for releasing the code -- very interesting work.
I remember clearly that MG for Possion equation has a complexity of O(N), as confirmed by Table 6.1 of Applied Numerical Linear Algebra. Indeed, your benchmark figure also looks closer to the O(N) line than O(NlogN) line.
A trivial calculation: a single V-cycle costs N + N/d + N/d^2 + ... + N/d^l = O(N)
where d
is reduction of grid size and l
is the total level. MG converges in a constant number of V-cycles, given some error threshold.
I can't seem to figure out how I can construct a FieldMatrix
if I have in hand the matrix (or sparsematrix) versions of operator A
. Is there a way to do that?
