Dear PETSc users,
The patch release petsc-3.5.1 is now available for download.
http://www.mcs.anl.gov/petsc/download/index.html
Some of the changes include:
* PCApplyRichardson_MG() did not properly set operators for all levels for residual computation Needed the same code as PCApply_MG() had
* if vector is of length 0 then VecSet() should set all norms to zero instead of triggering a divide by zero
* allow complex numbers to be used from both C and C++ (when supported) not only the language PETSc was built with
* improve the memory usage of PCGAMGCreateGraph()
* did not mirror 1d DMDA values correctly due to previous change consulidating block size -options_table should have been -options_view twenty years ago
* mpi4py: use current tarball mpi4py-1.3.1.tar.gz
* bugfix for memory leak with >1 processes and calling KSPSetOperators(A) twice with same A (see Jose Roman's email on Jul 11, 2014)
* At configure time determine if MPICH_NUMVERSION or OMPI_MAJOR/MINOR_VERSION or MPI-Uni, then at compile time make sure versions match to determine if incorrect mpi.h is being included
* petsc4py.py: look for python dynamic library in correct locations on Apple based on python version Test did not work correctly for anaconda installed python on Apple since that does not install a generic libpython.dylib
* Added code to properly preallocate "diagonal" portion of scalar matrix derived from vector matrix in PCGAMGCreateGraph()
* KSPCreate() for TAO GPCG solver is now done at TaoCreate_GPCG() instead of TaoSetUp() this allows users to change KSP options from the code easily and matches the style of other Tao solvers that use KSP
* TAO: Enable interface for complex scalar builds

We are pleased to announce the release of PETSc version 3.5 at http://www.mcs.anl.gov/petsc
The major changes and updates can be found at
http://www.mcs.anl.gov/petsc/documentation/changes/35.html
We recommend upgrading to PETSc 3.5 immediately. As always please report problems to
petsc-maint at mcs.anl.gov and ask questions at petsc-users at mcs.anl.gov
Notable new features/changes include
* KSPSetOperators(), SNESSetJacobian(), TSSetRHSJacobian(), and TSSetIJacobian()
no longer have a MatStructure argument, PETSc automatically tracks if the matrix structure has changed.
The Mat * arguments in these functions have also been changed to Mat
* the Tao scalable optimization software package is now included directly in the PETSc releases
* added DMNETWORK for simulations/computation on graphs, networks, and circuits
* DMDA requires much less memory usage in most situations
* --download-suitesparse now supports all solvers in suitesparse and replaces —download-umfpack and —download-cholmod
* added support for MKL’s Pardiso with ./configure --with-mkl_pardiso-dir and -pc_factor_mat_solver_package mkl_pardiso
* compiles of PETSc source now, by default, use GNU Make instead of Cmake and are more robust
* many addition/improvements to DMPlex unstructured mesh management
* there is no longer separate ISLocalToGlobalMappingBlock objects, instead the ISLocalToGlobalMapping
contains a block size
If you are using the threaded version of PETSc or PETSc on GPUs you should continue to work with
petsc-dev since this code is too much in flux to be contained in a release.
