<HTML><HEAD><TITLE>Coherent Virtual Machine (CVM)</TITLE></HEAD><BODY BACKGROUND="http://www.cs.umd.edu/~keleher/bkgnd.jpg"><h1>Coherent Virtual Machine (CVM)</h1><hr><BODY> The <b>C</b>oherent <b>V</b>irtual <b>M</b>achine (CVM) softwareDistributed Shared Memory (DSM) system is being developed here at theUniversity of Maryland. Project goals include:<ul><li><i>Multiple protocol support</i> - CVM's initial configuration provides fourmemory models, single- and multiple-writer versions oflazy release consistency, sequential consistency, and eager releaseconsistency. <li><i>Extensiblity</i> - CVM will be extensible in that thesource will be freely available, and the modules are being written in C++.New classes can easily be derived from a master Protocol class, allowingnew protocols to be easily incorporated. <li><i>Multi-threading support</i> - CVM is multi-threaded, allowing overlap of computationand communication through context switching. Additionally, we plan toextend themulti-threading support to multiprocessor nodes, such asDEC's <i>Sable</i> machines.<li><i>Fault-tolerance</i> - CVM will have a limited amount of faulttolerance, allowing it to recover from at least one node failure at a time.</ul><p><b>Status:</b> CVM currently runs on several different UNIX-like systems,including Sparcs, the SP-2, and Digital UNIX running on DECSables. Multi-threading support is undergoing performance-optimization. CVMwill be freely available, likely under the GNU CopyLeft. <hr><h3>Project Members:</h3><DL><DT><!WA0><IMG SRC="http://www.cs.umd.edu/fs/www/users/keleher/devil.gif" ALIGN=LEFT><BR><DL><DD><!WA1><a href="http://www.cs.umd.edu/~keleher">Dr. Pete Keleher</a><p><DD><!WA2><a href="http://www.cs.umd.edu/~dejanp">Dejan Perkovic</a><DD><!WA3><a href="http://www.cs.umd.edu/~kritchal">Kritchalach Thitikamol</a></DL><BR CLEAR=RIGHT><hr><!WA4><a href="http://www.cs.umd.edu/~keleher/papers.html"><strong>Papers</strong></a> (<!WA5><ahref="http://www.cs.umd.edu/~keleher/papers/cvm.ps.Z">CVM Manual</a>)<p><!WA6><a href="http://www.cs.umd.edu/~keleher/dsm.html"><strong>Related Projects</strong></a><p><!WA7><a href="http://www.cs.umd.edu/~keleher/bib/dsmbiblio/dsmbiblio.html""><strong>DSM Bibliography</strong></a><hr><I>Last updated on November 20, 1996</I></BODY>
