Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Industry Pick-up (1/2)  Layered shortest path routing (LASH) −SGI uses LASH recommends to use LASH for Altix systems with more than 128 nodes −NASA uses LASH on SGI hardware (Columbia cluster) −Sandia National Laboratories has announced to use LASH on Sun Hardware (Red Sky cluster)

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Industry Pick-up (2/2)  Routing on Fat-Tree topologies −The Sun Magnum constellation switch used this routing −Is currently not using it, but will switch to OpenFabrics implementation from Simula −The Texas Ranger supercomputer at Texas Advanced Computing Center (TACC) is uses it  Dynamic fault-tolerance in SCI −Dolphin Interconnect Solutions has implemented it in firmware and hardware

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Open Source  LASH in OpenFabrics The LASH routing methodology is part of OpenFabrics  TCP modifications in Linux Proposed for Linux next-net kernel Tested by Credit Suisse Requested for submission RT-Linux by RedHat, Novell and IBM

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Joint Research  SimTel −Jointly funded project with Telenor, currently employing 4 PhD students and 1 senior researchers −Current topics include current use of multiple wireless link and cognitive radio networks  Sunshine −Jointly funded 3-year research project with Sun Microsystems −Aimed at networking mechanisms for next generation supercomputers  Mellanox cooperation −Mellanox provides hardware for testing, especially on issues of congestion control mechanisms for InfiniBand networks

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Research Production

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Research Production  Publication venues are evaluated through the CORE ranking  Our venues −IEEE INFOCOM −ACM Multimedia −ACM NOSSDAV, SPIE/ACM MMCN, IEEE LCN, IEEE ICC, IEEE ICNP, ICPP, Euro-Par, IEEE IPDPS, HiPC −ICME, Globecom, CoNext

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Outlook (1/2)  Strategy −address fundamental problems of practical relevance −publish research results at a high international level −perform research that is internationally recognized be counted among their fields’ top research groups −success indicators program committees of highly ranked conferences guest editors for top journals invited talks conference keynote speakers attractiveness of Simula to visitors

Simula Evaluation Networks and Distributed Systems (ND)University of Oslo Outlook (2/2)  Strategy −focus even more on publishing at top conferences and in top journals −follow-up natural openings for cooperation across projects −intensify the use of experimentation to increase relevance, visibility, and trustworthiness of results −bring investigated tools and methods to public awareness −add to products where possible −do no rely on existing opportunities but build new ones −make use of EU for additional cooperation and funding
