    1. SFMA Wrap-up

    2. What we have learned: Barrelfish: Abstraction vs. Performance trade-off Get hardware designers to think of system’s level problems (e.g., protection) when building hardware Snapple Adapt both to H/W and to workload OctoPOS Need abstractions for resource reqs on very different H/W Ciel Many-core machines are the new data-centres

    3. What we have learned: Parallel Design Patterns Wrong multi-threading worse than none at all Shared-Nothing Transactional Memory Avoiding sharing can lead to better performance Dataflow transactions in Transactional Memory Transactional memory can provide an abstraction for incrementally adding data-flow computation On the Nature of Progress It’s possible to impose an order on progress conditions Panel Discussion Systems researchers have very strong opinions (and don’t always agree!)

    4. Thanks due: All authors who submitted All of the PC Keynote: Andrew Baumann The session chairs – Tim Harris & Derek Murray Panel Members - Maurice Herlihy, Stephan Diestelhorst & Paul Barham Co-Chairs – Joe Sventek, Tim Harris & Timothy Roscoe Everyone who attended!

    5. Next Steps Seems a lot of interest in this topic 2nd Workshop on Systems for Future Multi-Core Architectures Co-located with Eurosys 2012? Other conferences? If you are interested in being involved, talk to myself, Joe, Tim or Mothy rmcilroy@microsoft.com Pub!
