The PETSc maintenance e-mail, <a href="mailto:petsc-maint@mcs.anl.gov">petsc-maint@mcs.anl.gov</a>, is intended for
users to
<ul>
<li>report bugs, </li>
<li>ask for clarification, </li>
<li>ask for help in tracking down bugs, and </li>
<li>request new features within PETSc. </li>
</ul>
<p>We respond to almost all email the same day and many within the hour. <em>Please do not
send maintenance requests to the individual PETSc authors; all e-mail to</em> <strong><a href="mailto:petsc-maint@mcs.anl.gov">petsc-maint@mcs.anl.gov</a></strong> <em>is
automatically distributed to all of the PETSc authors, so our response time using this
address will be fastest. </em></p>
<p><!--webbot bot="PurpleText" PREVIEW="Do we want an archive of these available?
" -->Before
sending a bug report, please consult the following:</p>
<ul>
<li><a href="troubleshooting.html">troubleshooting guide</a>, and </li>
<li><a href="faq.html">FAQ</a></li>
</ul>
<p>to determine whether a fix or work-around to the problem already exists. Also, see the
chapter "Hints
for Performance Tuning" in the PETSc users manual for guidelines on achieving
good efficiency within PETSc codes. </p>
<p align="center"><strong><font size="4">Guidelines for Bug Reports</font></strong></p>

</li>
<li>MPI implementation: (e.g., MPICH, LAM, IBM, SGI) </li>
<li>Compiler: (e.g., Gnu C, Gnu g++, native C) </li>
<li>Probable PETSc component: (for example, <em>Mat, Vec, Draw, KSP</em>, etc.) </li>
