------------------ Portable, Extensible Toolkit for Scientific Computation (PETSc)-------------------- We are pleased to announce the release of PETSc 3.0; parallel software libraries for the implicit solution of PDEs and related problems involving sparse matrices. Major improvements include * PETSc modules and interface definitions for use from Fortran 90 * A much improved interface for using external direct solver packages include: MUMPS, SuperLU_DIST, PLAPACK and Spooles * A brand new Python interface (developed by Lisandro Dalcin) * An implementation of the Yand and Brent variant of Bi-CG-stab that requires a single parallel synchronization step per iteration * Preliminary support for unstructured meshes. The Sieve interfaces allows creation, manipulation, and output of unstructured meshes in any dimension (developed by Matt Knepley and Dmitry Karpeev) The software is available at http://www.mcs.anl.gov/petsc. Changes and additions are listed at http://www.mcs.anl.gov/petsc/petsc-as/documentation/changes/300.html . As always, please send bug reports, questions, and requests for new features to petsc-maint at mcs.anl.gov Thanks for your continued support. The PETSc developers, Satish, Lisandro, Matt, Dmitry, Victor, Barry and Hong
