<p>Several variables control the configuration and build
process
of PETSc. They can either be given as arguments to <font
color="#ff0000">make</font> or be set as environment
variables. </p>
<p><b><a name="PETSC_DIR"><font color="#551a8b">PETSC_DIR</font></a></b>:
- this
environment/make variable should point to the location of the PETSc
installation that is used. You can add <font color="#ff0000">export
PETSC_DIR=value</font> in your .profile or .sh file or <font
color="#ff0000">setenv PETSC_DIR value</font> in your
.cshrc or
.tcshrc
file. Multiple PETSc versions can coexist on the same
file-system. By changing PETSC_DIR one can switch between the
versions</p>
<p><b><font color="#551a8b">PETSC_ARCH</font></b>:
this
environment/make variable is used to specify the configuration that
should currently be used. It corresponds to the configuration files
in bmake/${PETSC_ARCH}. Multiple variants of PETSc libraries can be
installed - each variant corresponding to a different PETSC_ARCH. One
can switch between using these variants - by changing the value of
PETSC_ARCH. If PETSC_ARCH is not set, the configuration from the last
time you ran <font style="font-weight: bold;" color="#551a8b">./config/configure.py</font>
will
be used.</p>

provide
templates for Microsoft Visual Studio project files at
${PETSC_DIR}/projects. These work for us - with our configure build
[config/cygwin-ms.py with MPICH1 and Intel MKL 5], However they will
REQURE MODIFICATIONS to work with a user build of PETSc - as the
locations of packages & configure options used by user could be
different from our defult build. <br>
</p>
<p>To get these project files working for your installation of
PETSc, please do the following:<br>
</p>
<ul>
<li>try compiling the example from cygwin shell - using
makefile - for eg: <br>
cd src/ksp/ksp/examples/tutorials<br>
make ex2</li>
<li>if the above works - then make sure all the
compiler/linker
options used by make are also present in the project file in the
correct notation.<br>
</li>
<li>if errors - redo the above step. [if all the options
are
correctly specified - then the example should compile from MSDev.<br>

<p><b><font color="#551a8b">Debugger: </font></b>Running
PETSc probrams with -start_in_debugger is not supported on this
platform, so debuggers will need to be initiated manually. Make sure
your environment is properly configured to use the appropriate debugger
for your compiler. The debuggers can be initiated using Microsoft
Visual Studio 6: <b>msdev ex1.exe</b>, Microsoft
Visual Studio
.NET: <b>devenv ex1.exe</b>, Intel Enhanced
Debugger: <b>edb ex1.exe</b>,
or GNU Debugger <b>gdb ex1.exe</b>.</p>
<p><b><font color="#551a8b">PETSc Win32
front end - win32fe</font>:</b>
This tool is used as a wrapper to Microsoft/ Borland/ Intel compilers
and associated tools - to enable building PETSc libraries using make
and other UNIX tools. For additional info, run
${PETSC_DIR}/bin/win32/win32fe without any options.</p>

<p>If one has to go through the job scheduler to use MPI on a

</p>
<ul>
<li>run configure with the additional option <span

style="font-weight: bold;">frontend node</span> [perhpas with the
additional option <span style="font-weight: bold;">'--with-mpi-shared=0']</span><br>
</li>
<li>the above configure run will create a binary <span

'conftest' on <span style="font-weight: bold;">one compute node</span>
using the job scheduler.</li>
<li>The above run of conftest will create a new python script <span

To run any code compiled with MPI on IBM SP - one has to
go
through the <span style="font-weight: bold;">job scheduler</span>.
[So follow the instructions from the above section 'Installing on
machine requiring job scheduler']. Alternatively check/run
config/aix5.1.0.0.py for all
configure options
required on the SP with compilers defaulting to 32bit mode, and
config/aix5.1.0.0-64.py with compilers defaulting to 64bit mode.

<p>IBM Blue Gene [as of now] requires modified compiler

package and the prerequisite <a
href="http://www.cs.uoregon.edu/research/paracomp/pdtoolkit/">PDT</a>
packages need to be installed separately. PETSc provides a wrapper
compiler for TAU. This needs to be invoked with the correct information
for the installed TAU and PDT packages. For eg:<br>

<h3><a name="PythonBindings"><font color="#551a8b">Installing
TOPS components:</font></a></h3>
<p>To install TOPS components one has to download and
install CCA
Tools. [linux only]<br>
</p>
<ul>
<li>Get the CCA Tools package from <a
href="http://www.cca-forum.org/download/cca-tools/cca-tools-0.5.9.tar.gz">http://www.cca-forum.org/download/cca-tools/cca-tools-0.5.9.tar.gz</a></li>
<li>Configure cca-tools using '-with-mpi' option
[prerequisites
might be
Java SDK, c++, mpich1]</li>
<li>Configure PETSc with C++, babel, ccafe options.
Check config/asterix-tops.py for an example.<br>
</li>
<li>Build PETSc libraries & TOPS components with
'make all'<br>
</li>
<li>To test do: 'cd src/tops; make examples'<br>
</li>
</ul>
<h3><a name="PythonBindings"><font color="#551a8b">Installing the
Python Bindings:</font></a></h3>
<p>Currently, the automatic Python installtion works only
for the
developer release. The first step to installing the Python bindings is
to add the following 3 options to your configuration:<br>
<span style="color: rgb(255, 0, 0);">./config/configure
--with-shared --with-dynamic --with-python</span><br>
which will download the source for the bindings into <span
style="font-weight: bold;"><span style="color: rgb(85, 26, 139);">src/python</span>
</span>and
make sure that
PETSc can build dynamic libraries for the Python modules. If you have
the relase version, this download can be done manually using:<br>
<span style="color: rgb(255, 0, 0);">mkdir
src/python</span><br>
<span style="color: rgb(255, 0, 0);">cd
src/python</span><br>
<span style="color: rgb(255, 0, 0);">wget
ftp://ftp.mcs.anl.gov/pub/petsc/PETScPython.tar.gz .</span><br>
<span style="color: rgb(255, 0, 0);">tar xvzf
PETScPython.tar.gz</span><br>
After building PETSc, we can build the bindings using:<br>
<span style="color: rgb(255, 0, 0);">make python</span><br>
which will create python modules stored in <span
style="font-weight: bold;"><span style="color: rgb(85, 26, 139);">lib/PETSC_ARCH/PETSc</span>.</span>
