<br>Overview:<br>For Haskell there are currently no tools to investigate the performance
of parallel programs. This project would extend the Haskell compiler
GHC to support profiling of parallel programs. <br><br>Parallel
programs are inherently difficult to analyze and the prevalence of
multi-core processors has increased the need for tools to facilitate
gaining performance from parallelism. The ability to profile parallel
programs in GHC could lead to improvements in GHC's RTS, and insights
into writing parallel Haskell code. <br><br>Goals:<br> * Investigate the use of the GranSim framework for parallel profiling in GHC<br> i. Decide what is needed to commit the GranSim port to the GHC tree<br> i. Build additional profiling tools upon the GranSim framework<br>
<br> * Testing of performance hit accrued from parallel profiling<br> i. Investigate improving performance, possible modifications to GranSim port<br><br> * Construct tests to measure the performance improvements of parallel programs<br>
i. Building benchmarks for parallel programs, related to ticket: <br> <a href="http://hackage.haskell.org/trac/summer-of-code/ticket/1544" target="_blank">http://hackage.haskell.org/trac/summer-of-code/ticket/1544</a><br>
<br> * Improve upon GranSim visualization of profiles to clarify parallel profiling<br> i. Possibly add new visualization profiles, if time allows</blockquote><div><br><br> * Develop a single application for visualization of profiles<br id="oibz">
i. application would build visualizations <br> of the desired information as needed<br id="gd9g">
i. application would generate reports with specific numbers <br> from the analysis, rather than only images with graphs<br id="vcaq">
i. application would interactively sort / rank threads based <br> upon states, such as running, blocking, etc.<br id="wlkh">
i. application would integrate the visualization tools <br> into a single program (which may lead to support for <br> other profiling models than just parallelism)<br id="n.pq">

<div style="margin-left: 40px;"><br></div>I am sure that further details will need to be developed with the help of Simon Marlow; however, I am unsure if some of these details can be defined without first investigating the potential use of GranSim.<br>
<br>I look forward to your feedback.<br>
