pc | - the preconditioner Many br | |
n | - 0 or 1 Many br |
Notes: If A has a symmetric nonzero pattern use -sp 1 to Many brimprove performance by eliminating some communication Many brin the parallel version. Even if A does not have a Many brsymmetric nonzero pattern -sp 1 may well lead to good Many brresults, but the code will not follow the published Many brSPAI algorithm exactly. Many br
