PETSc users,
As some of you may be aware, we recently lost our developer
Kris Buschelman due to budget constraints. He will be missed. Rest assured
we will continue to be developing PETSc, just a little slower.
Our single most important way of maintaining PETSc funding is to
demonstrate that PETSc is a useful tool for those involved in
scientific computation. To assist us, please let us know of any recent
publications that relied on PETSc computations that are not listed at
http://www-unix.mcs.anl.gov/petsc/petsc-as/publications/index.html
Thanks for your support,
Barry

http://www.mcs.anl.gov/petsc
We are pleased to announce the release of the PETSc 2.2.1 parallel
software libraries for the implicit solution of PDEs and related
problems.
The change are listed at
http://www-unix.mcs.anl.gov/petsc/petsc-2/documentation/changes/221.html
download at
http://www-unix.mcs.anl.gov/petsc/petsc-2/download/index.html and
installataion instructions at
http://www-unix.mcs.anl.gov/petsc/petsc-2/documentation/installation.html
We now STRONGLY urge you to use config/configure.py to configure PETSc
rather than manually editing the bmake/$PETSC_ARCH files.
As always, please send bug reports, questions, and requests for new
features to petsc-maint(a)mcs.anl.gov.
Thanks for your continued support.

We are pleased to announce the release of the PETSc 2.2.0 parallel
software libraries for the implicit solution of PDEs and related
problems.
There is one major change. The SLES component is now GONE, all of its
functionality can be obtained through the KSP object. See
http://www.mcs.anl.gov/petsc/petsc-2/documentation/changes/220.html
for a list of changes in this release.
Though we still support the editing of $PETSC_DIR/bmake/$PETSC_ARCH/ files
for installing PETSc, we now also have a (semi) automatic configuration
tool that automatically sets up the configuration files: see
http://www.mcs.anl.gov/petsc/petsc-2/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.

PETSc users,
We are preparing our next PETSc release. In the next release we are
including a new tool config/configure.py that is intended to simplify
the installation of PETSc. It can determine the location of BLAS/LAPACK,
MPI and various other packages and also determine which options to use
for your compilers.
We would appreciate if as many people as possible could test this new
tool before our next release. All you need to do is
1) get the file ftp://ftp.mcs.anl.gov/pub/petsc/.petsc-dev.tar.gz
2) gunzip -c .petsc.tar.gz | tar -xof -
3) cd petsc
4) csh/tcsh: unsetenv PETSC_DIR
sh/bash: unset PETSC_DIR
5) ./config/configure.py
6) email petsc-maint(a)mcs.anl.gov the file configure.log
We will fix all the problems that come up during these runs; this
may make it quicker for your installs in the future.
If you are using the development version of PETSc you need only do
1) bk pull ; cd python/BuildSystem; bk pull
to update your source code, instead of getting the tar file.
Thanks
Barry
You can run config/configure.py --help to get a list of all options
--with-mpi=0 indicates you do not have an MPI installed
--with-gnu-compilers=0 you do NOT wish to use the gnu compilers
--with-vendor-compilers=0 you do not wish to use the vendor compilers
--with-fc=0 you do not want a Fortran compiler
--with-cxx=0 you do not want a C++ compiler
Dear PETSc users,
In order to continue funding of PETSc for support and further development
it is useful to have details of work that has been enabled or developed using
PETSc. To help us with this could you kindly send us any publications, websites
etc that feature work that you have done that used PETSc. You can see our
current list at http://www.mcs.anl.gov/petsc/petsc-2/publications.
Thanks for your support,
Barry

SLEPc: Scalable Library for Eigenvalue Problem Computations
http://www.grycap.upv.es/slepc
We are pleased to announce the release of SLEPc 2.1.5, a parallel
software library for the solution of large sparse eigenvalue problems on
parallel computers. It can be used for the solution of problems
formulated in either standard or generalized form, both Hermitian and
non-Hermitian, with either real or complex arithmetic.
SLEPc is built on top of PETSc, the Portable Extensible Toolkit for
Scientific Computation (http://www.mcs.anl.gov/petsc) It can be
considered an extension of PETSc providing all the functionality
necessary for the solution of eigenvalue problems. SLEPc includes
several eigensolvers as well as interfaces to other libraries such as
ARPACK. It also provides built-in support for spectral transformations
such as shift-and-invert.
This software should be considered as part of an ongoing project and we
plan to continue its improvement by adding more solvers and tools.
Please send bug reports, questions, and requests for new features to
slepc-maint(a)grycap.upv.es

PETSc users,
Please update us with recent publications/websites/products
that you have done using PETSc. (Our current list is at
www.mcs.anl.gov/publications) This material helps us receive
funding from the Department of Enery for the development, maintenance,
and support of PETSc.
Thanks,
Barry Smith for the PETSc team
PETSc-users,
The DOE SciDAC Performance project (http://perc.nersc.gov/) is looking
for interesting parallel applications to help with performance
modeling, analysis, and optimization. If you are interested in releasing
your code and collaborating with this group, please contact Paul
Hovland at hovland(a)mcs.anl.gov. Unfortunately they are restricted to
working with codes that are mainly developed in the United States.
As always, thanks for your support,
Barry
