You can find the current list of preconditioners on line 40 here: http://www.mcs.anl.gov/petsc/petsc-current/include/petscpc.h.html
You can click on the names to be taken to man pages. However, since preconditioners are by nature problem-dependent, it's a better idea to try to look up what might be an appropriate preconditioner for your system and then see how to use PETSc to apply it. There's a high probability that what you need is supported either natively by PETSc or as Jed's note demonstrates, through interfaces to external libraries (of which there are a large number - run ./configure -help to get an idea of the options available and the configure flags to use them) > Il giorno 16/apr/2015, alle ore 23:54, huaibao zhang > <[email protected]> ha scritto: > > Hello there, > > I have been confused of the extent of the available preconditioners in PETSc > for a while.
