|
2007/01/11: Migrated repository to SVN.
|
|
|
|
2007/01/11: MLD2P4 has been moved to the new org. Now tackling the
|
|
test dirs.
|
|
|
|
2007/01/09: First try at reorganizing directories. Subdir MLD2P4 still
|
|
to be fixed. Documentation still to be updated.
|
|
|
|
2006/12/11: Documented options in glob_to_loc.
|
|
|
|
2006/12/06: Fixed raw aggregation.
|
|
|
|
2006/12/05: Taken out extra interfaces; inserted use modules with ONLY
|
|
clauses where appropriate.
|
|
|
|
2006/11/30: Fixed a bug in raw aggregation. Note: raw aggregation
|
|
gives different results from smoothed with omega=0.0,
|
|
because in the latter we have explicitly stored zero
|
|
coefficients that would be absent in the first, thus
|
|
generating different ILU factorizations.
|
|
|
|
2006/11/28: Merged the mods for descriptors of large index spaces to
|
|
avoid having the GLOB_TO_LOC array. Took the chance to
|
|
reorganize the descriptor build routines and define some
|
|
access functions for descriptor features and entries, so
|
|
as not to use the descriptor components directly. Tested
|
|
with AS, 2- and 3- level Post smoothers.
|
|
|
|
2006/11/09: The allocatable version works, but under gcc42 there is a
|
|
compiler bug when using -fbounds-check.
|
|
|
|
2006/11/08: Merged the allocatable version; hope everything works!
|
|
|
|
2006/11/08: Branched version psblas2-2-0-maint, and defined tag
|
|
2.0.2.6
|
|
|
|
2006/11/02: Done in the allocatable branch: repackaging of cdasb and
|
|
friends, taking out AVL trees where they were not
|
|
absolutely needed, and new dcsrmv routine.
|
|
|
|
2006/11/01: Merged changes in the handling of data exchange.
|
|
|
|
2006/10/03: Merged in the multilevel preconditioner stuff. This is
|
|
still experimental, especially the interfaces are not
|
|
stable yet.
|
|
|
|
2006/10/03: Declared version 2.0.2.5 for reference purposes.
|
|
|
|
2006/10/03: Fixed a bunch of minor bugs, incuding the sorting routines
|
|
imsr and imsrx. Added a default call to blacs_exit inside
|
|
psb_exit fixed a bad termination in test/pargen/ppde90.f90
|
|
|
|
2006/09/02: Declared version 2.0.2, after having fixed a lot of
|
|
details in the environment routines.
|
|
|
|
2006/07/25: Defined a new psb_wtime function. Modified precset to
|
|
have a non-optional INFO dummy argument.
|
|
|
|
2006/07/06: Fixed bug in swaptran. Added psb_krylov generic interface.
|
|
|
|
2006/07/04: Ooops, the GetRow mod in SMMP is a performance hit.
|
|
Need to investigate further.
|
|
|
|
2006/06/21: Bug fix in hb_read when dealing with symmetric matrices.
|
|
|
|
2006/06/20: Rewritten symbmm and numbmm from SMMP to be intependent of
|
|
CSR storage by using GetRow. Still need to test for
|
|
performance.
|
|
|
|
2006/06/16: Defined GetRow. This way we may close the mat objects.
|
|
Next we will rewrite SMMP to only make use of GetRow,
|
|
not to rely on CSR storage format.
|
|
|
|
2006/05/29: Added BLACS-like routines for data communication,
|
|
broadcasts, reductions, send/receive.
|
|
|
|
2006/05/25: Added environment management routines.
|
|
|
|
2006/05/03: Bug fixes, plus some change in the internals for SPINS,
|
|
preparing hooks for insertion with local numbering.
|
|
|
|
2006/04/24: Minor changes to the interface of dense tools routines,
|
|
trying to achieve a uniform look & feel.
|
|
Rewritten documentation; it is now reasonable, though not
|
|
perfect, except for the preconditioner routines.
|
|
We can now declare RC3.
|
|
|
|
2006/04/21: A bunch of fixes related to various matrix initialization
|
|
problems that were revealed while testing on SP5.
|
|
|
|
2006/04/18: Changed interface to spasb and csdp: better handling of
|
|
regeneration. To be tested further for sophisticated uses.
|
|
|
|
2006/03/31: We declare RC2 now. Improved I/O routines in test/Fileread.
|
|
|
|
2006/03/24: We have a complex version now, working (not necessarily bug free).
|
|
|
|
2006/03/15: Started move to complex version.
|
|
|
|
2006/03/01: Complete restructure of PREC section.
|
|
|
|
2006/02/01: New naming scheme.
|
|
|
|
2006/01/01: New multilevel preconditioning wih smoothed aggregation.
|
|
|
|
2005/09 : Now enabled UMFPACK complete factorization as basis for AS.
|
|
|
|
2005/05/04: Now enabled SuperLU complete factorization as basis for AS.
|
|
|
|
2005/04/29: First version with decoupled 2-level.
|
|
|
|
2005/04/06: Started work on decoupling the preconditioner aggregation
|
|
for 2-level from the main factorization.
|
|
|
|
2005/03/30: First version of new DSC/SP allocate/insert/assembly
|
|
routines.
|
|
2005/03/17: First version of RGMRES. To be refined.
|
|
|
|
2005/03/08: dSwapTran aligned with dSwapData. Taken out SwapOverlap.
|
|
also moved onto iSwapX.
|
|
|
|
2005/03/07: dSwapData rewritten to achieve: 1. better performance;
|
|
2. more flexible functionality. It is now possible to
|
|
avoid SwapOvrlap entirely, relying on just SwapData.
|
|
SwapTran is still alive, since it reads the descriptors in
|
|
"transpose" mode. Also, added work areas to preconditioner
|
|
routine, to avoid excessive allocation in the halo/overlap
|
|
exchange.
|
|
|
|
2005/03/04: Had to put in a workaround for a gfortran bug:
|
|
tolower/toupper cannot be functions.
|
|
|
|
2005/02/09: Explicit storage choice for the smoother. This seems
|
|
to be changing a little bit the actual preconditioner.
|
|
To be evaluated further.
|
|
|
|
2005/02/08: Renamed F90_PSPREC to PSB_PRCAPLY and Preconditioner to
|
|
PSB_PRCBLD. Changed the way PRCAPLY decides what to do.
|
|
Still needs a PSB_PRCSET to be called before PRCBLD.
|
|
|
|
2005/01/28: Started moving functionalities to a SERIAL F90 layer. Also
|
|
defined a new COMM layer, to enable implementing SPMM
|
|
directly in F90.
|
|
|
|
2005/01/20: Finally taken out a direct call to the F77 DCSDP from
|
|
SPASB.
|
|
|
|
2005/01/18: After much work, we now have 2-level Additive Schwarz
|
|
prototype implemented and working. We now start a major
|
|
code cleanup that will take some time. Mainly we want to
|
|
move a lot of the serial F77 functionality into a new F95
|
|
serial layer, to simplify the parallel F95 code.
|
|
|
|
2004/11/25: Following the introduction of Additive Shwarz and
|
|
variants, we have now renamed DECOMP_ and friends as
|
|
DESC_; this makes things more readable. Sooner or later
|
|
we're going to merge this into mainline, but this version
|
|
is still very much in a state of flux.
|
|
|
|
2004/07/18: For use with gfortran we need to declare the pointer
|
|
components with NULL() initialization. This rules out
|
|
VAST and PGI.
|
|
|
|
2004/07/15: First development version with gfortran from the current
|
|
snapshot of gcc 3.5.0.
|
|
It is now possible in PSI_dSwapData to opt for
|
|
SEND|RECEIVE|SYNC data exchange; plan is to extend to all
|
|
data exchange functions, plus making it available as an
|
|
option from the F90 level.
|
|
|
|
2004/07/06: Merged in a lot of stuff coming mainly from the ASM
|
|
development; full merge will have to wait a little more.
|
|
Among other things:
|
|
use of psimod
|
|
new choice parms for overlap
|
|
new data exchange for swapdata, to be extended.
|
|
multicolumn CSMM.
|
|
use psrealloc
|
|
new format for marking a matrix as suitable for update.
|
|
|
|
|
|
2003/12/09: Changed DSALLOC and DSASB to make sure whenever a dense
|
|
matrix is allocated it is also zeroed out.
|
|
|
|
2003/10/13: Added call to BLACS_SET in the solvers to ensure global
|
|
heterogeneous coherence in the combine operations.
|
|
|
|
2003/09/30: Added LOC_TO_GLOB and GLOB_TO_LOC support routines.
|
|
|
|
2003/09/30: Changed interface for smart update capabilities: choose
|
|
with optional parameters in ASB routines.
|
|
|
|
2003/09/16: IFC 7.0 had a strange behaviour in the test programs:
|
|
sometimes the declaration of PARTS dummy argument with an
|
|
INTERFACE would not work, requiring an EXTERNAL
|
|
declaration. The proper INTERFACE works now with 7.1.
|
|
|
|
2003/03/10: Halo data exchange in F90_PSHALO can now be applied to
|
|
integer data; create appropriate support routines.
|
|
|
|
2002/12/05: Initial version of Fileread sample programs.
|
|
|
|
2002/11/19: Fixes for JAD preconditioner.
|
|
|
|
2002/11/19: Methods for patterns: create a descriptor without a
|
|
matrix.
|
|
|
|
2001/11/16: Reviewed the interfaces: in the tools section we really
|
|
need the POINTER attribute for dense vectors, but not in
|
|
the computational routines; taking it out allows more
|
|
flexibility.
|
|
|
|
2001/09/16: Smart update capabilities.
|
|
|
|
2001/03/16: Renumbering routines.
|
|
|
|
2001/01/14: Added extensions to compute multiple DOTs and AMAXs at once;
|
|
|
