<p><a href="index.html"><b>New News...</b></a></p>
<p><b>April 7, 2004:</b> Up to now, all Carpet thorns have been
living in a single arrangement for Cactus. This caused problems,
because stable thorns, development thorns, and outdated thorns
were sitting next to each other, confusing newcomers. We have <a
href="get-carpet-darcs.html">moved the Carpet arrangement</a> to a
new repository and split it into four. Access to the old Carpet
arrangement has been disabled.</p>
<p><b>March 3, 2004:</b> We have recently had trouble with I/O
throuth the <a
href="http://zeus.ncsa.uiuc.edu/~jshalf/FlexIO/">FlexIO</a>
library. We suspect that it might have a bug that causes HDF5
output to fail under certain, random conditions. We have written
a new thorn CarpetIOHDF5 which uses the <a
href="http://hdf.ncsa.uiuc.edu/HDF5/">HDF5</a> library directly,
while remaining compatible to the FlexIO file format. Please test
this thorn, and report any problems or incompatibilities you
find.</p>
<p>In <b>January 2004</b>, <a
href="http://www.tat.physik.uni-tuebingen.de/~kobras/">Daniel
Kobras</a> set up <a href="http://bugs.carpetcode.org/">Bugzilla
for Carpet</a>. <a href="http://www.bugzilla.org/">Bugzilla</a>
is a bug-tracking system that will, so we hope, help us remember
what is missing or broken in Carpet.</p>
<hr />
<p>In <b>October 2003</b>, Erik Schnetter, Scott H. Hawley, and
Ian Hawke published the preprint "Evolutions in 3D numerical
relativity using fixed mesh refinement" as <a
href="http://arXiv.org/abs/gr-qc/0310042">gr-qc/0310042</a>. Its
main point is to present tests of Carpet with the BSSN code (AEI's
spacetime evolution code), and to show that mesh refinement does
not introduce instabilities.</p>
<p>In <b>August 2003</b>, <a
href="http://www.carpetcode.org/">these web pages</a> were
created.</p>
<p><b>May 2003</b> has informally been termed <a
href="CarpetMonth/index.html">"Carpet month"</a>. In a flurry of
activity, bugs were fixed and some features added. The BSSN code
of the numerical relativity group at the <a
href="http://www.aei.mpg.de/">AEI</a> now works together with
Carpet.</p>
