Many different kinds of applications can benefit from multi-core parallelism, including add-ins to Microsoft Office. Donny Amalo wrote a paper, PLINQ and Office Add-ins, where he demonstrates how to implement two parallel Microsoft Office add-ins using PLINQ: (This paper and many more are available through the Parallel Computing ...

Despite the similarity in naming, the System.Threading.Tasks.Parallel class and the System.Activities.Statements.Parallel* activities in WF4 are largely orthogonal in the scenarios they address. However, WF4 activities and the new parallel programming types in .NET 4 can be used together to great advantage.Ling Wo and Cristina Manu wrote ...

PLINQ’s Ordering Model

June 21, 2010 Jun 21, 2010 06/21/10
Igor Ostrovsky - MSFT
In order to execute parallel queries as efficiently as possible, Parallel LINQ (PLINQ) treats ordering as optional. By default, PLINQ considers sequences to be unordered, unless the user explicitly opts into maintaining ordering using either the AsOrdered or the OrderBy operator.Roy Patrick Tan wrote a detailed article that...
