registering preconditioners
Solves a linear system in parallel with KSP,
demonstrating how to register a new preconditioner (PC) type.
Input parameters include:
-m <mesh_x> : number of mesh points in x-direction
-n <mesh_n> : number of mesh points in y-direction
setting a user-defined shell preconditioner
Solves a linear system in parallel with KSP. Also
illustrates setting a user-defined shell preconditioner and using the
Input parameters include:
-user_defined_pc : Activate a user-defined preconditioner
setting a user-defined shell preconditioner
Solves a linear system in parallel with KSP. Also indicates
use of a user-provided preconditioner. Input parameters include:
