etienne:

Hello,

I am putting together a student proposal to participate in Google's Summer of Code with one of the following project ideas.

Parallel programming benchmarking and benchmark suite - http://hackage.haskell.org/trac/summer-of-code/ticket/1544

Are there open source projects and real world applications that rely on GHC's parrallel programming primitives and libraries? I have found

There's many applications on hackage that depend on Control.Concurrent, forkIO, Channels, MVars and software transactional memory. Relatively few yet depend on `par` and lightweight parallelism.

many references to LOLITA, but it seems to be old and not available online. The idea page suggests porting existing benchmark suites such as PARSEC, but PARSEC is 5G of C code. Most of it seems to come from existing applications already written in C. It might also be

Yes, the benefit here would be to build up a set of haskell programs that do lean on the parallel libraries and primitives. Porting algorithms from the benchmark suite would be one useful way to do that.

interesting to automate the discovery of optimal strategies through empirical data, and to modify the thresholds dynamically.

See the recent paper by Satnam Singh and Tim Harris, http://research.microsoft.com/~satnams/fdp.pdf on feedback-directed implicit parallelism for Haskell.

Parallel profiling tools for GHC - http://hackage.haskell.org/trac/summer-of-code/ticket/1559

Simon Marlow wrote on the idea page that Gransim was ported to a more up-to-date GHC. The documentation available on the web seems to be for GHC 0.29 but it describes many options for logging and visualising the activity of threads and processors over time. Getting GHC to display that information on the frontpanel would make a nice project.

Do you have any comments or suggestions?

Thank you,
