Industry Pick-up (1/2) Layered shortest path routing (LASH)

−SGI uses LASHrecommends 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 2009 -- 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

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 2009 -- 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
