Ulf Wiger, CTO of Erlang Training and Consulting

 Ulf  Wiger Ulf Wiger became one of the first commercial users of Erlang (certainly the first in North America) when he bought a license in 1993. At the time, he was busy designing disaster response systems in Alaska. In 1996, he joined Ericsson and became Chief Designer of the AXD 301 development. At nearly 2 million lines of Erlang code, AXD 301 is the most complex system ever built in Erlang, and probably the most complex commercial system built in any functional language. In recent years, Ulf has been involved in several products based on the AXD 301 architecture, and has been an active member of the Open Source Erlang community. In February 2009, Ulf began his new job as CTO of Erlang Training and Consulting.

Presentation: "Concurrency Expert Panel"

Time: Tuesday 13:30 - 14:30

Location: Archauz


One theme of the panel is concurrent programming models. Specifically; classic locking, transactional memory and actors. And with concurrency we mean parallel systems (e.g. shared-memory multicore, cluster)

  • The goal is performance
  • One trust domain
  • Latencies are small and predicable
  • One failure => kill the program is just about tolerable
  • One of the goals for the discussion would be to get a better understanding of strengths and weaknesses; advice and discussion about when to use which model.

Another goal is:

  • for the audience to get to pick the brains of the experts
  • to get a good discussion going amongst the experts
  • to get concrete advice on choice of programming language (hence model) for certain problems.
  • advice on solving common problems that appear when using a particular model.
