The value of the platform is further * increased by support for low-overhead language interoperation, as well as a general instrumentation * framework that supports multi-language debugging and other external developer tools. * <p> * Open Source Truffle implementations of both R and Ruby demonstrate excellent performance, and * Sulong supports Truffle implementations of all LLVM-based languages. * <p> * Truffle is part of the Graal Project, developed and maintained by * <a href="http://labs.oracle.com/">Oracle Labs</a> * and the * <a href="http://www.jku.at/isse/content">Institute for System Software</a> of the * Johannes Kepler University Linz. * <p> * For additional information, please visit: * <ul> * <li>The Graal project home: <a href="https://github.com/graalvm">https://github.com/graalvm</a></li> * <li>Truffle home: <a href="https://github.com/graalvm/truffle">https://github.com/graalvm/truffle</a></li> * <li>Sulong home: <a href="https://github.com/graalvm/sulong">https://github.com/graalvm/sulong</a></li> * <li><a href="http://www.oracle.com/technetwork/oracle-labs/program-languages/overview/index-2301583.html">Graal VM</a> * download on the Oracle Technology Network</li> * <li><a href="https://github.com/graalvm/truffle/blob/master/docs/Publications.md#truffle-presentations">Truffle Presentations and Publications</a></li> * <li><a href="https://github.com/graalvm/sulong/blob/master/docs/PUBLICATIONS.md">Sulong Presentations and Publications</a></li> * <li><a href="https://github.com/graalvm/graal-core/blob/master/docs/Publications.md#graal-papers">Graal Publications</a></li> * <li><a href="https://github.com/graalvm/simplelanguage">SimpleLanguage</a>: the tutorial Truffle language implementation.</li> * <li><a href="https://github.com/graalvm/fastr/blob/master/README.md">FastR</a>: an Open Source Truffle implementation of the R language</li> * <li><a href="https://github.com/graalvm/truffleruby/blob/master/README.md">TruffleRuby</a>: an Open Source Truffle implementation of the Ruby language</li> * <li>Mailing list for developers <a href="mailto:graal-dev@openjdk.java.net">graal-dev@openjdk.java.net</a> * <li>{@linkplain com.oracle.truffle.tutorial Other Truffle Tutorials} * </ul> * * </div> <script src="../doc-files/tutorial.js"></script> * * @since 0.25 */ package com.oracle.truffle.tutorial.background;
