|
|
!
|
|
! This version of the preconditioner module psb_prec_mod renames "on the fly"
|
|
! the MLD2P4 preconditioner routines and data types so that the Krylov solvers
|
|
! in PSBLAS can be tricked into using the MLD2P4 versions instead of the original
|
|
! ones. Since there is no native runtime polymorphism this implies a recompilation,
|
|
! but thanks to the renaming feature of Fortran 95 (and to the compatibility of
|
|
! the calling sequences) there is no need to change the source code for the
|
|
! Krylov methods.
