Release of PETSc 3.4
by Barry Smith 22 May '13

22 May '13

We are pleased to announce the release of PETSc version 3.4 at http://www.mcs.anl.gov/petsc The major changes and updates can be found at http://www.mcs.anl.gov/petsc/documentation/changes/34.html We recommend upgrading to PETSc 3.4 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 include a system for managing unstructured grids with PDE solvers in DMPlex. Capability and performance improvements to the algebraic multigrid preconditioners PCGAMG, many new nonlinear solvers in SNES, many improvements to the ODE solvers in TS including the new TSEIMEX, and support for parallel dense linear algebra using MatElemental. The library also has better encapsulation and better control of symbols. 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.

Using PETSc from MATLAB code, experimental
by Barry Smith 25 Dec '10

25 Dec '10

PETSc users, It is now possible to write MATLAB programs (sequential) that use PETSc KSP, SNES, and TS solvers directly in MATLAB. The code is still experimental and incomplete. But if you are interested in trying it out, get the development release of PETSc http://www.mcs.anl.gov/petsc/petsc-as/developers/index.html join the development mailing list petsc-dev http://www.mcs.anl.gov/petsc/petsc-as/miscellaneous/mailing-lists.html, read bin/matlab/classes/PetscInitialize.m, configure and make PETSc and join the fun. We are definitely in need of more developers for this code. Barry

release of PETSc 3.1
by Barry Smith 25 Mar '10

25 Mar '10

PETSc users, We are pleased to announce the release of PETSc 3.1; we urge all users of PETSc 3.0 and earlier versions to upgrade in the near future. We (Hong Zhang and Shrirang Shri) have provided new triangular solve routines for all the sparse matrix data structures which should result in a good performance improvement with many of the solvers. As always the changes/additions to the PETSc API can be found at http://www.mcs.anl.gov/petsc/petsc-as/documentation/changes/31.html please report all installation and usage problems to petsc-maint(a)mcs.anl.gov Thanks for your support, Barry

Unique funding opportunity ARPA-E
by Barry Smith 04 May '09

04 May '09

If you are using PETSc in an energy related area and could make a major breakthrough with additional resources (and lots of help from us) there is a unique funding opportunity from the U.S. Department of Energy (as usual with these things you must be more or less U.S. based). Please let me know if you are interested in trying, with a little background on your project, Thanks Barry > > >
