+<h3>Monday, October 14, 2013, 10am US central time</h3>
+<p>The <a href="http://horizon.tapir.caltech.edu/demo/einsteintoolkit.jsp"><i
+>Einstein Toolkit</i></a> BigBlueButton meeting was be used for audio and slides. The
+slides are available as <a href="IllinoisGRMHD.pdf">pdf</a>, and the recordings are
+available in <a href="recording/2013_10_14.ogv">Theora</a> or
+<a href="recording/2013_10_14.mp4">MP4</a> format..

+<h3>Abstract</h3>
+<p>
+After months of work, I am pleased to release my rewrite of the Illinois
+numerical relativity group's staggered A-field GRMHD thorn to the ET
+community. The new thorn is called IllinoisGRMHD, and yields results
+identical (within roundoff error) to the original GRMHD code of the
+Illinois group with AMR & unigrids, with bitant symmetry & without, and
+with single or multiple MPI processes. We used precisely these GRMHD
+algorithms to produce our latest GRMHD-based papers.
+
+IllinoisGRMHD is written entirely in C, except for some C++ file I/O for
+debugging purposes, and all loops are OpenMP-compatible. The coding
+standard is C99.
+
+I would like to thank Frank and the CCT folks, who have graciously agreed
+to host IllinoisGRMHD on the ET SVN server, as the thorn awaits
+maintainers' approval for incorporation into the official ET.
+
+Download IllinoisGRMHD via the following command:
+<pre>
+svn co https://svn.einsteintoolkit.org/cactus/EinsteinEvolve/IllinoisGRMHD/trunk/
+</pre>
+
+<a href="https://svn.einsteintoolkit.org/cactus/EinsteinEvolve/IllinoisGRMHD/trunk/">Browse</a> IllinoisGRMHD source code in your web browser.
+</p>
+
+<h4>Background</h4>
+<p>
+Roughly a decade of work has gone into the original code, and nearly all of
+the credit for debugging that battle-hardened code goes to Stu Shapiro and
+other former & current members of his group, to whom I give my great thanks
+and send the following message: Despite weeks entirely devoted to debugging
+this rewritten code, I found no major bugs in the original code.
+</p>
+
+<h4>License</h4>
+<p>
+The IllinoisGRMHD thorn is hereby released under the GNU GPL v2 or higher,
+to maximize compatibility with the ET thorns.

+Numerical Relativity Group Research interests: My research interests span all
+of computational astrophysics. Much of my past work has focused on simulating
+the mergers of compact binary systems, including BHNS, BHBH, WDNS, and NSNS. My
+current work focuses on BHBH mergers, as well as studying MHD effects in BHNS
+mergers.
