Simon Thompson
Creator of Wrangler and co-author of Erlang Programming
The University of Kent
Simon Thompson is Professor of Logic and Computation in the School of Computing of the University of Kent, where he has taught computing at undergraduate and postgraduate levels for the past twenty eight years, and where he was formerly department head for seven years and is currently Director of Research and Enterprise.
His research work has centered on functional programming: program verification, type systems, and most recently development of software tools for functional programming languages. His team has built the Wrangler tool for refactoring Erlang programs, as well as performing clone detection and allowing users to extend the tool with their own refactorings. His research has been funded by various agencies including EPSRC and the European Framework programme. His training is as a mathematician: he has an MA in Mathematics from Cambridge and a D.Phil. in mathematical logic from Oxford.
He has written four books in his field of interest; Type Theory and Functional Programming published in 1991; Miranda: The Craft of Functional Programming (1995), Haskell: The Craft of Functional Programming (3rd ed. 2011) and Erlang Programming (with Francesco Cesarini, 2009). Apart from the last, which is published by O'Reilly, these are all published by Addison Wesley.

Simon Thompson is Giving the Following Talks
Profiling Erlang programs using Percept2
The number of cores in modern computer system is increasing rapidly, and Erlang's support for multi-core system is also being continuously improved. To take full advantage of the computing power provided by multi-core Erlang, new Erlang applications need to be written with more parallelism to assure that there are enough processes ready to run, and existing sequential Erlang applications can be refactored to introduce more parallelism and therefore scalability. However, very often one might find that an application does not scale as expected.
In this talk, we present the Erlang concurrency profiling tool Percept2, which is an enhanced version of the original Erlang concurrency profiling tool Percept. Built on top of Percept, Percept2 provides not only process profiling information, but also scheduler and function profiling information. Visualisation and navigation through data is made easy in Percept2, and the performance has also been improved by the parallelisation of tool itself. We demonstrate how Percept2 can be used to find Erlang application level bottlenecks, and also how the tool can be used to provide guidance and feedback on the parallelisation of existing sequential Erlang applications.
