Changelog. A lot less detailed than usual, at least for past
history.
2009/01/28: Changed names from XbaseprcY to XbaseprecY.
2009/01/27: Changed names from mld_transfer to mld_move_alloc.
2009/01/13: Repackaged the one-level preconditioners. Reorganized the
build routines, taking out mlprec_bld, and switching the
number of levels when needed.
2008/10/27: Changed the definition of prec_type: repackaged with a
onelev-prec-type, containing a baseprec and maps between
index spaces. No performance impact; no changes to
user-level interfaces.
2008/09/18: Changed mld_sizeof to integer(8); updated samples.
2008/08/26: Fixed matrix generation in sample programs.
2008/07/25: missing implicit none in mld_prec_type.
2008/07/23: added HTML documentation
2008/06/13: Fixed aggregation for replicated index spaces.
2008/06/02: Threshold into decoupled aggregation algorithm.
2008/05/27: Single precision version.
2008/03/09: Introduced configure script.
2008/02/08: Merged changes from intermesh branch: we now have an
inter_desc_type object. Cleaned up data allocation and
variable initialization in multilevel prec application.
2008/01/10: Merged various fixes for: prologues, unused variables,
interface details.
2007/12/21: Merge version with prologues and internal docs.
2007/11/15: Created pargen example.
2007/11/14: Fix INTENT(IN) on X vector in preconditioner routines.
2007/10/19: Merged in ILU(P,T). To be tested extensively.
2007/10/17: Merged ILU(K) into trunk.
2007/10/16: Fixed ILU(K), it now performs satisfactorily. Also updated
ILU(0) to be more legible.
2007/10/11: First working version of ILU(K). Still slow, there should
be room for improvement.
2007/10/09: Added benchmark code.
2007/10/09: Added MILU_N_. Beware: values for UMF_ etc. have been
shifted.
2007/10/02: To do: decide whether to name MLD_KRYLOV_MOD or
PSB_KRYLOV_MOD.
2007/10/01: Start of this changelog. MLD2P4 now has a different
structure, to enable a build not embedded in PSBLAS.
