Specifying the desired degree of parallelism in .Net 4.0 TPL Beta 1

Posted on Intel Software Network
Sometimes, you don’t want to use all the available cores in a parallel loop. Why? Because you have better plans for the remaining available cores. Thus, you want to specify the concurrency level of a parallel loop. Luckily, Task Parallel Library Beta 1 will allow you to do this using the new ParallelOptions class.

C# 2008 and 2010, multicore, .Net Parallel Extensions and PLINQ

The book includes a lot of content dedicated to .Net Parallel Extensions (currently in CTP) and PLINQ (Parallelized LINQ). They will be available in C# 2010 (C# 4.0) and .Net 4.0.
This video shows the application developed in Chapter 11: Coding with .NET Parallel Extensions.
The chapter’s table of contents:
