    ABSTRACT:: In this paper, we consider iterative solution procedures for
               solving singular linear systems Ax = b, b $\varepsilon$ Range
               (A) where A is an n by n, Hermitian, positive semidefinite
               matrix. Our aim is to consider variants of the block Jacobi,
               SOR, and SSOR iterations. The fundamental paper of Keller
               ([1965]) considers methods based on splittings A = B - C with
               B a nonsingular matrix. Here we allow B to be singular.
