<h2><a name="CHANGES">CHANGES in PETSc 2.1.6</a></h2>
</div>
<h4>General:</h4>
<ul>
<li>Added support for Cray X1</li>
<li>
Added option '-suggest' to petscarch script. It suggests some
possible PETSC_ARCHes to use
</li>
<li>Installation instructions are rewritten</li>
</ul>
<h4>Vec:</h4>
<ul>
<li> VecNorm now caches NORM_2</li>
<li>Added VecStrideScale(), VecStrideGather(), VecStrideScatter()</li>
<li>Added VecBlockNorm(),VecBlockMax(),VecBlockMin(),VecBlockScale()</li>
</ul>
<h4>Mat:</h4>
<ul>
<li>
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
</li>
<li>
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
</li>
<li>
Changed default matrix-free compute h to use WP since it uses fewer
reductions
</li>
<li>Replace the datatypes MatLUInfo and MatILUInfo by MatFactorInfo</li>
<li>Added cholesky support to SeqAIJ</li>
<li>Added support for SUBSET_NONZERO_PATTERN with MatAXPY for AIJ & BAIJ</li>
<li>Added MatIsSymmetric() for AIJ</li>
<li>Added LDA support in SeqDense</li>
<li>The ncols argument made optional in MatGetRow()</li>
<li>Added MAT_KEEP_ZEROED_ROWS for MPIROWBS</li>
<li>Removed -aij_oneindex support from AIJ code</li>
<li>Added MatPartitioningSetPartitionWeights() - useable with ParMetis</li>
<li>MatGetSubMatrices() now works for ROWBS</li>
</ul>
<h4>PC:</h4>
<ul>
<li>Added PCICCSetDamping() or -pc_icc_damping</li>
<li>Added -pc_constant_null_space</li>
<li>Added PCILUSetShift() or -pc_ilu_shift to support damping using the identity</li>
<li>Added PCLUSetShift() or -pc_lu_shift to support damping using the identity</li>
<li>Added PCICCSetShift() or -pc_icc_shift to support damping using the identity</li>
</ul>
<h4>KSP:</h4>
<ul>
<li>Added a new ksp_type LGMRES</li>
<li>Added KSPSetComputeSingularValues() support to ksp_type FGMRES</li>
</ul>
<h4>TS:</h4>
<ul>
<li>Added support for Runge-Kutta using ts_type TS_RUNGE_KUTTA</li>
</ul>
<h4>DMMG:</h4>
<ul>
<li>-dmmg_jacobian_period -1 => jacobian is frozen after initial construction</li>
</ul>
<h4>DA:</h4>
<ul>
<li>Allow user preallocation of jacobian using DASetGetMatrix()</li>
<li>DAGetMatrix now correctly returns the requested type.</li>
<li>-mat_type typename overloads the requested type for DAGetMatrix</li>
</ul>
<h4>SYS:</h4>
<ul>
<li>Added new viewer_type PETSC_VIEWER_NETCDF, PETSC_VIEWER_HDF4</li>
<li>PETSc error handlers now trap many more signals.</li>
</ul>
<h4>Fortran:</h4>
<ul>
<li>PetscPushErrorHandler() and PetscPopErrorHandler() now supported</li>
<li>PetscPrintf() and PetscSynchronizedPrintf() now work in fortran with a single string</li>
</ul>
<h4>External Packages:</h4>
<ul>
<li>Added TSPVodeGetParameters()</li>
<li>Parmetis-3 support added using MatPartitionSetNParts(), ISPartitionCount()</li>
<li>MUMPS support added, including complex (using mat_type MATAIJMUMPS, MATSBAIJMUMPS)</li>
<li>Updated SuperLU_DIST interface to SuperLU_DIST_2.0</li>
<li>Added Spooles complex support</li>
<li>Added Spooles cholesky for SeqAIJ</li>
<li>
ADIC: ad_GRAD_MAX is now set in the application and compiled into
code when compiling appplication
</li>
<li>
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
</li>
</ul>
