2037 1032d 20h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Davidon solvers support computing the residual associated to all eigenvalues in the searching subspace
2023 1043d 02h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Improved the performance of dvd_calcpairs_selectPairs_qz
- Added the mpd support to davidson solvers
- Improved the checking of the parameters for the davidson solvers
2012 1046d 09h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Adapted veccomp, precond, gd and jd to PETSc with c++
2008 1050d 03h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - CHKERRQify the functions dvd_schm_basic_{conf,preconf}
1997 1057d 10h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Made STPrecondGetMatForPC(st,P) be equivalent to STGetKSP(st,ksp), KSPSetOperator(ksp,0,P)
- Infinite value shifts supported by STPrecond
- Adapted Davidson solvers for STPrecond
1992 1064d 02h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Corrected the state of the vectors in functions in dvd_blas
- Removed many calls to PetscObjectStateIncrease in VecComp object because the PETSc interface for Vec does it
- Completed the code that frees all the allocated objects by the Davidson solver
1991 1064d 08h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Davidson uses the eps->conv_func as convergence test
1987 1066d 21h eromero /trunk/src/eps/impls/davidson/common/dvd_schm.c - Merging from branches/davidsones to trunk
1985 1067d 09h eromero /branches/davidsones/src/eps/impls/davidson/common/dvd_schm.c - Renamed EPS_DAVIDSONES to EPS_DAVIDSON
- Changed davidsones.* davidson.*
- Removed the custom fortran wrapper tags from the EPSGDGet*
1980 1071d 01h eromero /branches/davidsones/src/eps/impls/davidson/common/dvd_schm.c - Include EPSGD???InitialSize and -eps_gd_initial_size replacing -eps_davidsones_initv
- Removed the experimental macros EPSObj{Get,Set}{Prop,2Props} and replacing by functions in traditional PETSc manner
- Added 3 projectors more
- Removed dvd_improvex_{gdbasic,gdolsen}. The GD is implemented by dvd_improvex_jd with ksp==0. Advantages: less code and GD can use the JD projectors
1976 1074d 05h eromero /branches/davidsones/src/eps/impls/davidson/common/dvd_schm.c - Transformation of the experimental Davidson solver "DAVIDSONES" to a full integrated family of solvers "davidson". The first solver is "gd". The code shared by the "davidson" solvers is packaged by the virtual solver "DAVIDSON": EPSSetUp_DAVIDSON, EPSSolve_DAVIDSON...
- Partially fixed bug: the size of the starting searching subspace is set by eps->nini, but this value can be negative.
- Integration of "davidsones_harm" as "eps_extraction"
1965 1099d 09h eromero /dvd_schm.c - bug fixed: residual vector in complex case but real arithmetic is computed with normalized eigenvectors
- bug fixed: a ksp doesn't allow operators of different size; so VecComp can operate with a virtual size
- bug fixed: RJDQZ needs that JD correction equation operates with eigenvectors instead of Schur vectors. For that the projectors of JD correction equation can operate with any projection of the left and right subspaces
- bug fixed: block size adapted to RJDQZ
- Added an UpdateVectors routine for non-contiguous stored vectors
- bug fixed: enforced restarting when improveX doesn't add any vector
- bug fixed: recomputing eigenvalues adapted to RJDQZ
- bugs fixed in SlepcUpdateVectorsS and SlepcUpdateStrideVectors
- lots of minor bug fixed...
1883 1207d 00h eromero /dvd_schm.c - Independent harmonic target and EPS target
- Added the 'fix' parameter for JD
- Homogeneous EPS target representation
- Fixed bug: error extracting the eigenvectors from the converged Schur decomposition for the complex case
- Fixed bug: harmonic eigenpairs weren't back-transformed
- Updated the Krylov initial subspace and added as new option
- Added 'calcpairs_proj_res' for custom residual computation
- Standard problems solved with harmonic are handled as generalized
- Fixed minor bugs in 'dvd_calcpairs_projeig_qz_gen', 'dvd_schm_basic_preconf', 'dvd_managementV_basic'
- 'dvd_improvex_jd_proj_uv_0' implements an advance correction equation, instead of a collection
- Bug fixed: 'dvd_jacobi_precond' test if MatGetDiagonal is available
- Bug fixed: corrected some harmonic transformations
- Changed HarmType_t to enum type
- Added function lists called in the starting and in the ending of EPSSolve
- Improved the support of preconditioners
1875 1240d 06h eromero /dvd_schm.c The user initial subspace routine allows to add random vectors.
1874 1241d 19h eromero /dvd_schm.c - First support for multiple initial vectors
- Davidson solver adaptation for the multiple initial vectors interface
1867 1269d 20h eromero /dvd_schm.c First version of Jacobi-Davidson variant based on Manel Cruz (mbc@isep.ipp.pt) code
1809 1333d 03h eromero /dvd_schm.c - Update of olsen variant for harmonics version
1795 1336d 06h eromero /dvd_schm.c - Rewriting of updating, restarting and converging routines
- First implementation of harmonics (only largest eigenvalues tested). For some ncv, the solver doesn't converge or converge to wrong eigenpairs. Moreover, it is unstable when the number of processors grows
1777 1352d 10h eromero /dvd_schm.c Create a branch for davidsones with MatMultZ, because the resulting improvement is not important enough.
1764 1395d 02h eromero /dvd_schm.c - calculate H and J in one reduction at dvd_improvex_gdolsen_undef_std function.
- support for B-orthonormal version.
- the convergence test takes account of X norm.
Warning: dvd_improvex_gdbasic is not support.
