Waiting for Tasks

Parallel Extensions makes it easy to wait for Tasks to complete.  Task exposes a Wait method, which can be used trivially:Task t = Task.Create(...); ... t.Wait();Task also exposes several static methods for waiting on an array of tasks, either for all of them to complete or for any of them to complete:Task t1 = Task.Create(...); Task t2...

Feedback requested: TaskManager shutdown, Fair scheduling

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 ...

Custom Loop with Arbitrary Initialization, Condition, and Update

The Parallel.For loop construct provided by Parallel Extensions is focused on providing a parallel alternative to the common sequential pattern of a for loop that iterates over a range of numbers.  However, the for loop construct in a language like C# is not limited just to numbers and iterating over ranges.  It supports arbitrary ...

Useful Abstractions Enabled with ContinueWith

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 ...

Mandelbrot in Parallel with C++/CLI

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 ...
