There have been many enhancements and bug fixes since 2011. </p> <p>This package also provides <code><a href="makeCluster.html">makeForkCluster</a></code> to create socket clusters by forking (not Windows). </p> <p>For a complete list of exported functions, use <code>library(help = "parallel")</code>. </p> <h3>Author(s)</h3> <p>Brian Ripley, Luke Tierney and Simon Urbanek </p> <p>Maintainer: R Core Team <a href="mailto:R-core@r-project.org">R-core@r-project.org</a> </p> <h3>See Also</h3> <p>Parallel computation involves launching worker processes: functions <code><a href="../../tools/html/psnice.html">psnice</a></code> and <code><a href="../../tools/html/pskill.html">pskill</a></code> in package <span class="pkg">tools</span> provide means to manage such processes. </p> <hr /><div style="text-align: center;">[Package <em>parallel</em> version 3.6.0 <a href="00Index.html">Index</a>]</div> </body></html>
