DESCRIPTION:Accessing network adapters directly from user-space applicatio
 ns improves performance dramatically\, and this technique has been used fo
 r many years in the HPC space where it was invented.  Recently it has beco
 me possible to accelerate mainstream applications that use the standard so
 ckets interfaces and standard protocols.  This environment throws up some 
 serious challenges\, such as the exec() call which blows away all user-lev
 el state!  In this seminar I'll show how Solarflare's OpenOnload stack has
  solved this and other hard problems in user-level networking.\n\nBio: Dav
 id Riddoch is Chief Architect at Solarflare\, which he co-founded in July 
 2002.  David is the architect of OpenOnload\, Solarflare's OS-bypass netwo
 rk stack\, which delivers ultra high performance without requiring changes
  to applications.  David oversees the design and implementation of Solarfl
 are's software and hardware interfaces\, and still gets to write some code
