Yes, the diagonal scaling is broken in 0.83 (in fact, there was no
scaling in previous versions, despite the flag in solver.par). This will

At the moment, there is the small help included in the solver.par
file... An excellent reference documenting the various solvers available
in getdp is:
@book{saad-book-96,
author = "Y. Saad",
title = "Iterative Methods for Sparse Linear Systems",
publisher = "PWS Publishing Company",
year = 1996
