Changes: 2.1.6

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
