Dryad is a Microsoft Research project dedicated to developing ways to write parallel and distributed programs that can scale from small clusters to large datacenters. There's a DryadLINQ compiler and runtime related to the project. Microsoft released builds of Dryad and DryadLINQ code to academics for noncommercial use in summer 2009. Microsoft is now planning to move the Dryad stack from Microsoft Research to Microsoft's Technical Computing Group. The plan is to deliver a first Community Technology Preview test build of the stack in Nov 2010 and to release a final version of it running on Windows Server High Performance Computing servers by 2011, according to a slide from an August 2010 presentation by one of the principals working on Dryad.
