Feedback requested: TaskManager shutdown, Fair scheduling

August 1, 2008 Aug 1, 2008 08/1/08

Stephen Toub - MSFT

One of the primary reasons we've released CTPs of Parallel Extensions is to solicit feedback on the design and functionality it provides. Does it provide all of the APIs you need to get your job done? Are there scenarios you wished the APIs supported and that you need to work around in klunky ways? And so forth. We've ...

Useful Abstractions Enabled with ContinueWith

July 24, 2008 Jul 24, 2008 07/24/08

Stephen Toub - MSFT

In the June 2008 CTP of Parallel Extensions to the .NET Framework, we introduced the ContinueWith method on both Task and Future<T>. ContinueWith is, in effect, a callback, very much like events in .NET. With events, a causal action results in the event being raised, which by default triggers all of the delegates registered ...

Charles from Channel 9 came over to building 112 last week for an in-depth look at what's new in the June 2008 CTP of Parallel Extensions.

Mandelbrot in Parallel with C++/CLI

June 6, 2008 Jun 6, 2008 06/6/08

Stephen Toub - MSFT

Since the release of the December 2007 CTP of Parallel Extensions, we've received several questions about whether Parallel Extensions can be used from C++/CLI. In short, yes, it can! (It can be used with any .NET language, one of the beauties of this functionality being provided through a library.) To demonstrate, we included in ...

Multiple thread-local state elements in a loop

May 28, 2008 May 28, 2008 05/28/08

Stephen Toub - MSFT

The Parallel.For/ForEach loop constructs included in Parallel Extensions support a variant of thread-local state to aid in efficiently passing data between loop iterations.
