I&#39;d suggest looking into TotalView (<a href="http://www.totalviewtech.com">http://www.totalviewtech.com</a>) and/or DDT (<a href="http://www.allinea.com/">http://www.allinea.com/</a>).  I&#39;ve used TotalView pretty extensively and found it to be pretty easy to use.  They are both commercial, however, and not cheap.  <br>
<br>As far as I know, there isn&#39;t a whole lot of open source support for parallel debugging. The Parallel Tools Platform of Eclipse claims to provide a parallel debugger, though I have yet to try it (<a href="http://www.eclipse.org/ptp/">http://www.eclipse.org/ptp/</a>).<br>
