Microsoft has began external developer testing of various interrelated parallel/distributed technologies for Windows Server that are part with the codename “Dryad” family.According to a December 17 blog post on the Windows HPC (High Performance Computing) Team Blog, Microsoft is making available to testers via its Connect test site the first Community Technology Preview (CTP) test builds of its Dryad, DSC and DryadLINQ technologies.Dryad is Microsoft;s competitor to Google MapReduce and Apache Hadoop. In the early phase of its existence, Dryad was 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 that is related to the project. Microsoft released builds of Dryad and DryadLINQ code to academics for noncommercial use in the summer 2009. Microsoft moved Dryad from its research to its Technical Computing Group this year.According to a presentation from August, the team;s plan was to deliver a first CTP build with the stack in November 2010 and to release a final version of it running on Windows Server High Performance Computing servers by 2011.This initial preview is intended for “developers who are exploring data-intensive computing,
Office 2010 Activation,” according to the Softies. The prerequisite for the CTP is HPC Pack 2008 R2 Enterprise-based cluster, with Service Pack 1 installed.As I noted in a previous blog post, there are many interesting components that comprise Dryad, including a new distributed filesystem (codenamed “TidyFS”), a set of related data-management tools (codenamed Nectar”) and a scheduler for distributed clusters (codenamed “Quincy”).
