I was wondering if it handles per-thread information when you have more than one thread involved. (Actually the question is not related to the graphical tool, but the announcement triggered it).<br>Best.<br>Cristian<br><br>

<div style=""><br><div><br></div><div>I am pleased to announce the first release of prof2dot, a graphical profiling tool</div><div>for use with GHC.</div><div><br></div><div>While GHC has in the past worked with graphical profiling tools, they </div>
<div>have been heavyweight and/or proprietary. Prof2dot is a simple tool for</div><div>converting profiling information into a graphical format, released under a BSD3</div><div>license. It is simple because it offloads all of the work of rendering the graph</div>
<div>onto Graphviz. So you need to install the Graphviz tools in order to use it.</div><div><br></div><div>The program is a filter that takes the profiling output generated by running</div><div>a GHC-compiled program with the "+RTS -px -RTS" option and turns it into</div>
<div>a dot file. (The "dot" format is a textual representation of a directed or undirected graph.)</div><div>The dot file can rendered in any format supported by Graphviz's</div><div>dot program, and the file itself can be post-processed or edited to adjust the</div>
<div>layout.</div><div><br></div><div>Features of prof2dot:</div><div><br></div><div><span style="white-space: pre;"> </span>* display either the call graph (default) or the call tree,</div><div><br></div><div><span style="white-space: pre;"> </span>* colorize by cost center count, time or allocations,<br>
</div><div><br></div><div><span style="white-space: pre;"> </span>* group cost centers in the same module.<br></div><div><br></div><div>Prof2dot installs as a typical caballized application.</div><div>Running "prof2dot -?" from the command line will give a short summary of</div>
<div>how to use the program and its options.</div><div><br></div><div>Rendering very large graphs can exceed the internal resource limits of dot.</div><div>You may have to compile your own version of the Graphviz tools with higher limits</div>
<div>to handle these cases.</div><div><br></div><div>A example of a colorized profile of a medium sized project is shown on our</div><div>company's web site: ht<a href="http://antiope.com/downloads.html" target="_blank">tp://antiope.com/downloads.html</a>. Click on the small</div>
