PETSc
    
    
    
    
    
    
    
      
      General:
      
        - Added support for Cray X1
- 
          Added option '-suggest' to petscarch script. It suggests some
          possible PETSC_ARCHes to use
        
- Installation instructions are rewritten
Vec:
      
        -  VecNorm now caches NORM_2
- Added VecStrideScale(), VecStrideGather(), VecStrideScatter()
- Added VecBlockNorm(),VecBlockMax(),VecBlockMin(),VecBlockScale()
Mat:
      
        - 
          The interface to external packages that support direct solvers has
          been reorganized. This is implemented using new matrix types
          MATSEQAIJSPOOLES, MATMPIAIJSPOOLES, MATSEQSBAIJSPOOLES,
          MATMPISBAIJSPOOLES, MATSUPERLU, MATSUPERLU_DIST, MATUMFPACK,MATESSL,
          MATLUSOL, MATAIJMUMPS, MATSBAIJMUMPS, MATDSCPACK
        
- 
          Added new convenience matrix types which automatically switch between
          Seq and MPI implementations depending on the size of the communicator
          used during creation: MATAIJ, MATBAIJ, MATSBAIJ, MATMAIJ, MATDENSE,
          MATBDIAG
        
- 
          Changed default matrix-free compute h to use WP since it uses fewer
          reductions
        
- Replace the datatypes MatLUInfo and MatILUInfo by MatFactorInfo
- Added cholesky support to SeqAIJ
- Added support for SUBSET_NONZERO_PATTERN with MatAXPY for AIJ & BAIJ
- Added MatIsSymmetric() for AIJ
- Added LDA support in SeqDense
- The ncols argument made optional in MatGetRow()
- Added MAT_KEEP_ZEROED_ROWS for MPIROWBS
- Removed -aij_oneindex support from AIJ code
- Added MatPartitioningSetPartitionWeights() - useable with ParMetis
- MatGetSubMatrices() now works for ROWBS
PC:
      
        - Added PCICCSetDamping() or -pc_icc_damping
- Added -pc_constant_null_space
- Added PCILUSetShift() or -pc_ilu_shift to support damping using the identity
- Added PCLUSetShift() or -pc_lu_shift to support damping using the identity
- Added PCICCSetShift() or -pc_icc_shift to support damping using the identity
KSP:
      
        - Added a new ksp_type LGMRES
- Added KSPSetComputeSingularValues() support to ksp_type FGMRES
TS:
      
        - Added support for Runge-Kutta using ts_type TS_RUNGE_KUTTA
DMMG:
      
        - -dmmg_jacobian_period -1 => jacobian is frozen after initial construction
DA:
      
        - Allow user preallocation of jacobian using DASetGetMatrix()
- DAGetMatrix now correctly returns the requested type.
- -mat_type typename overloads the requested type for DAGetMatrix
SYS:
      
        - Added new viewer_type PETSC_VIEWER_NETCDF, PETSC_VIEWER_HDF4
- PETSc error handlers now trap many more signals.
Fortran:
      
        - PetscPushErrorHandler() and PetscPopErrorHandler() now supported
- PetscPrintf() and PetscSynchronizedPrintf() now work in fortran with a single string
External Packages:
      
        - Added TSPVodeGetParameters()
- Parmetis-3 support added using MatPartitionSetNParts(), ISPartitionCount()
- MUMPS support added, including complex (using mat_type MATAIJMUMPS, MATSBAIJMUMPS)
- Updated SuperLU_DIST interface to SuperLU_DIST_2.0
- Added Spooles complex support
- Added Spooles cholesky for SeqAIJ
- 
          ADIC: ad_GRAD_MAX is now set in the application and compiled into
          code when compiling appplication
        
- 
          The following variable names - in the buildsystem are changed - that
          correspond with SuperLU_DIST SUPERLUDIST_INCLUDE ->
          SUPERLU_DIST_INCLUDE SUPERLUDIST_LIB -> SUPERLU_DIST_LIB
          PETSCHAVE_SUPERLU -> PETSC_HAVE_SUPERLU
