PETSc 3.0 release
by Barry Smith 21 Dec '08

21 Dec '08

> ------------------ 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

New PETSc release 2.3.3
by Barry Smith 24 May '07

24 May '07

---------------------------------------------------------------------------- Portable, Extensible Toolkit for Scientific Computation (PETSc) ---------------------------------------------------------------------------- http://www.mcs.anl.gov/petsc We are pleased to announce the release of the PETSc 2.3.3 parallel software libraries for the implicit solution of PDEs and related problems. There are a couple of MAJOR interface changes, listed at http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/changes/233.html please check these changes before compiling your codes. In particular the calling sequence for VecScatterBegin/End() now takes the scatter context as the first argument not the last. You can download from http://www-unix.mcs.anl.gov/petsc/petsc-as/download/index.html and and the installataion instructions are at http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/installation.html As always, please send bug reports, questions, and requests for new features to petsc-maint(a)mcs.anl.gov Thanks for your continued support.

higher level interfaces to PETSc?
by Barry Smith 24 Mar '07

24 Mar '07

PETSc-users, A representative of Interactive Supercomputing has asked us to gauge if there is interest among PETSc users in calling PETSc from higher level systems such as Matlab (and presumably money to pay for it :-). I've attached a portion of the message below. If you are interested please drop a note to Robert McGill <robert_mcgill(a)comcast.net>. Barry ---------- Forwarded message ---------- Date: Mon, 19 Mar 2007 12:39:16 -0500 From: Robert McGill <robert_mcgill(a)comcast.net> We have several customers interested in linking their MATLAB routines to PDE solvers such as those offered by PETSc. To date, we have linked to several libraries but not specifically to PETSc. We are working with some of the folks on the Trilinos project and am curious to find out if there are users in the PETSc community who are interested in calling PETSc from a high level language such as MATLAB or R or IDL. Our product, Star-P is a parallel processing platform that is used by VHHL users to not only run their client applications in parallel, but also to make calls to libraries such as PETSc directly from MATLAB and R via the Star-P Connect SDK.

Please do not send zip or even .tar.gz or .tgz files to petsc-maint
by Barry Smith 09 Jun '05

09 Jun '05

PETSc users, We've been losing PETSc-maint emails that contain zip or gzip files that many mail servers delete. Please end only plain ascii email to petsc-maint; you can attach files like configure.log directly, please do not compress them first. Thanks Barry We appologize to those whose email may have been lost.

DOE seeks INCITE proposals for 2006 (fwd)
by Barry Smith 16 May '05

16 May '05

PETSc users, If you receive funding from any US agency and have very high end computational needs you might consider applying. Barry The DOE Office of Science has committed 10 percent of its high-end computing resources at NERSC, Oak Ridge and Argonne, and five percent of the high-end computing resources at Pacific Northwest National Lab, for large-scale computational science projects. The Innovative and Novel Computational Impact on Theory and Experiment (INCITE) call for proposals is at: http://hpc.science.doe.gov/

new PETSc release
by Barry Smith 28 Apr '05

28 Apr '05

---------------------------------------------------------------------------- Portable, Extensible Toolkit for Scientific Computation (PETSc) ---------------------------------------------------------------------------- http://www.mcs.anl.gov/petsc We are pleased to announce the release of the PETSc 2.3.0 The CHANGES in this release are a bit more extensive then usual. 1) You MUST use config/configure.py to install PETSc, see http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/installation.html 2) The BOPT option to determine optimization/debugging and C/C++ compiles is GONE. Now you use a different PETSC_ARCH (for example linux-g and linux-O) for different optimizations and set the optimization as a config/configure.py option. See http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/changes/230.html 3)* The prototypes of many methods, for example VecScale, MatShift, ... have been changed to take the Vec or Mat object as the FIRST argument, otherwise the arguments are the same as before. See http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/changes/230.html for a complete list of the functions changed. As always, please send bug reports, questions, and requests for new features to petsc-maint(a)mcs.anl.gov. Thanks for your continued support. The PETSc developers, * this change was made to make all the PETSc calls more "object oriented" so we could have the same calling sequences for our new PYTHON PETSc binding.
