ParallelOptions.MaxDegreeOfParallelism vs PLINQ’s WithDegreeOfParallelism

May 29, 2009 May 29, 2009 05/29/09
Stephen Toub - MSFT
We exert a good deal of effort ensuring that the APIs we provide are consistent within Parallel Extensions as well as with the rest of the .NET Framework.  This is from many angles, including behavior and general design, but also naming.  So when there are slight differences in naming, it raises questions.One occurrence of such a ...

Partitioning in PLINQ

Partitioning in PLINQ Every PLINQ query that can be parallelized starts with the same step: partitioning.  Some queries may even need to repartition in the middle.  Partitioning is a fairly simple concept at the high level: PLINQ takes a lock on the input data source, breaks it into multiple pieces, and then distributes these to the...

.NET 4 Cancellation Framework

May 22, 2009 May 22, 2009 05/22/09
Mike Liddell
A very interesting addition to .NET 4 is a set of new types that specifically assist with building cancellation-aware applications and libraries. The new types enable rich scenarios for convenient and safe cancellation, and help simplify situations that used to be be difficult and error-prone and non-composable. The details of the new types ...
