When building the colmap array for prolongation operators that contain a high number of nonzero coefficients living in P_offd, see hypre_build_interp_colmap, the code will make P_offd_size * num_cols_P_offd comparisons, and this can be very high depending on the test case. This PR eliminates such code path and uses a hash table to accomplish the same purpose, thus lowering the algorithmic complexity. |
