9. def at_a(operator: OpAtA[_], srcRdd: DrmRddInput[_]): DrmRddInput[Int]

   Materialize A'A operator

10. def at_a_group(op: OpAtA[_], srcRdd: DrmRdd[_]): DrmRddInput[Int]

11. def at_a_nongraph(op: OpAtA[_], srcRdd: DrmRdd[_]): DrmRddInput[Int]

    The version of A'A that does not use GraphX

12. def at_a_nongraph_mmul(op: OpAtA[_], srcRdd: BlockifiedDrmRdd[_]): DrmRddInput[Int]

    The version of A'A that does not use GraphX.

    The version of A'A that does not use GraphX. Tries to use blockwise matrix multiply. If an accelerated matrix back is available, this might be somewhat faster.

13. def at_a_slim(operator: OpAtA[_], srcRdd: DrmRdd[_]): Matrix

    Computes A' * A for tall but skinny A matrices.

    Computes A' * A for tall but skinny A matrices. Comes up a lot in SSVD and ALS flavors alike.
