Many br
Notes: x^{n+1} = x^{n} + scale*B(b - A x^{n}) Many br
Here B is the application of the preconditioner Many br
This method often (usually) will not converge unless scale is very small. Many br
Notes: For some preconditioners, currently SOR, the convergence test is skipped to improve speed, Many brthus it always iterates the maximum number of iterations you've selected. When -ksp_monitor Many br(or any other monitor) is turned on, the norm is computed at each iteration and so the convergence test is run unless Many bryou specifically call KSPSetNormType(ksp,KSP_NORM_NONE); Many br
For some preconditioners, currently PCMG and PCHYPRE with BoomerAMG if -ksp_monitor (and also Many brany other monitor) is not turned on then the convergence test is done by the preconditioner itself and Many brso the solver may run more or fewer iterations then if -ksp_monitor is selected. Many br
Supports only left preconditioning Many br
