Number of nonzeros of the projected matrix onto the null-space basis Z of the block [C.sup.T] (see Algorithm 3.1, Step 3), iteration counts and timings of the preconditioned conjugate gradient method applied to the orthogonally projected indefinite system compared to the memory requirements and iteration counts for the solution of the same system based on the sparse QR decomposition of its off-diagonal block [Z.sup.T] B.
The JCG iterative method is the simplest in a class of preconditioned conjugate gradient methods. It is not, however, robust enough to replace the frontal solver.
Algorithms: the block preconditioned steepest descent and the locally optimal block preconditioned conjugate gradient method. In the present paper, we shall consider two methods: the preconditioned steepest descent (PSD) and the locally optimal preconditioned conjugate gradient method (LOPCG) as well as their block analogs: the block preconditioned steepest descent (BSPD) and the locally optimal block preconditioned conjugate gradient method (LOBPCG), in the form they appear in [34, 36].
