!
|
|
! Subroutine: amg_dprecseti
|
|
! Version: real
|
|
!
|
|
! This routine sets the integer parameters defining the preconditioner. More
|
|
! precisely, the integer parameter identified by 'what' is assigned the value
|
|
! contained in 'val'.
|
|
! For the multilevel preconditioners, the levels are numbered in increasing
|
|
! order starting from the finest one, i.e. level 1 is the finest level.
|
|
!
|
|
! To set character and real parameters, see amg_dprecsetc and amg_dprecsetr,
|
|
! respectively.
|
|
!
|
|
!
|
|
! Arguments:
|
|
! p - type(amg_dprec_type), input/output.
|
|
! The preconditioner data structure.
|
|
! what - integer, input.
|
|
! The number identifying the parameter to be set.
|
|
! A mnemonic constant has been associated to each of these
|
|
! numbers, as reported in the AMG4PSBLAS User's and Reference Guide.
|
|
! val - integer, input.
|
|
! The value of the parameter to be set. The list of allowed
|
|
! values is reported in the AMG4PSBLAS User's and Reference Guide.
|
|
! info - integer, output.
|
|
! Error code.
|
|
! ilev - integer, optional, input.
|
|
! For the multilevel preconditioner, the level at which the
|
|
! preconditioner parameter has to be set.
|
|
! If nlev is not present, the parameter identified by 'what'
|
|
! is set at all the appropriate levels.
|
|
!
|
|
! NOTE: currently, the use of the argument ilev is not "safe" and is reserved to
|
|
! AMG4PSBLAS developers. Indeed, by using ilev it is possible to set different values
|
|
! of the same parameter at different levels 1,...,nlev-1, even in cases where
|
|
! the parameter must have the same value at all the levels but the coarsest one.
|
|
! For this reason, the interface amg_precset to this routine has been built in
|
|
! such a way that ilev is not visible to the user (see amg_prec_mod.f90).

! Subroutine: amg_dprecsetr

! Version: real

|
!
|
|
! This routine sets the real parameters defining the preconditioner. More
|
|
! precisely, the real parameter identified by 'what' is assigned the value

! contained in 'val'.
|
|
! For the multilevel preconditioners, the levels are numbered in increasing

|
|
! To set integer and character parameters, see amg_dprecseti and amg_dprecsetc,

! Arguments:

! p - type(amg_dprec_type), input/output.

! The preconditioner data structure.
|
|
! what - integer, input.
|
|
! The number identifying the parameter to be set.
|
|
! A mnemonic constant has been associated to each of these
|
|
! numbers, as reported in the AMG4PSBLAS User's and Reference Guide.
|
|
! val - real(psb_dpk_), input.
|
|
! The value of the parameter to be set. The list of allowed
|
|
! values is reported in the AMG4PSBLAS User's and Reference Guide.
|
|
! info - integer, output.
|
|
! Error code.
|
|
! ilev - integer, optional, input.
|
|
! For the multilevel preconditioner, the level at which the
|
|
! preconditioner parameter has to be set.
|
|
! If nlev is not present, the parameter identified by 'what'
|
|
! is set at all the appropriate levels.
|
|
!
|
|
! NOTE: currently, the use of the argument ilev is not "safe" and is reserved to
|
|
! AMG4PSBLAS developers. Indeed, by using ilev it is possible to set different values
|
|
! of the same parameter at different levels 1,...,nlev-1, even in cases where
|
|
! the parameter must have the same value at all the levels but the coarsest one.
|
|
! For this reason, the interface amg_precset to this routine has been built in
|
|
! such a way that ilev is not visible to the user (see amg_prec_mod.f90).
