Task Parallel Library Improvements in .NET 4.5

by Jonathan Allen on  Dec 02, 2011

Microsoft has been working on ways to improve the performance of parallel applications in .NET 4.5, specifically those using the Task Parallel Library. One of most impressive improvements is reducing the overhead for waiting on 100,000 tasks from 12,000,000 bytes to a mere 64 bytes.

Task Parallel Library for Silverlight

by Jonathan Allen on  Aug 25, 2011 4

Silverlight’s asynchronous service model forces developers to deal with multi-threading from the very beginning. So it seems odd that Microsoft choose to omit the Task Parallel Library, which is the core of .NET’s multi-threading infrastructure. Fortunately there are options.

Software Architecture in the Movies

by Michael Stal on  Jul 31, 2011

Keeping up-to-date with software architecture can be a tough endeavor. Information is normally available within thick books or somewhere hidden in the Web. Another more entertaining way can be to watch clips available at video sites such as YouTube and Vimeo.

Rx 1.0 Solves the Problem of Asynchronous Data Access

by Abel Avram on  Jun 30, 2011

C++ AMP Provides Massive Parallelism

by Abel Avram on  Jun 16, 2011 1

Microsoft wants to give C++ developers tools for writing parallel applications running on zillions of GPUs/cores locally or in the cloud.

Explaining .NET’s Barrier Class

by Jonathan Allen on  Jun 15, 2011

With the increased emphasis on multi-core systems an understanding of parallel and concurrent programming is more important than ever. Fortunately .NET 4 has made a lot of advances in the types of synchronization primitives available to developers. One such primitive is the Barrier, which Emad Omara uses to implement a parallel merge sort.

Erlang Copied Scala's Actors & Erlang's VM is almost a Clone of the JVM

by Sadek Drobi on  Apr 01, 2011 8

Erlang Co-creators, Joe Armstrong and Robert Virding, admit that Erlang is heavily inspired by the Java world. In an interview at ErlangFactory 2011 SF, they reveal how Scala Actors had shaped their work in what they then called Erlang Processes. Moreover, they acknowledge the fact that Erlang's VM is barely a clone of the famous JVM.

Robert Harper and Dan Licata, Professors of Computer Science at Carnegie Mellon University, announced last week that they have decided to "eliminate entirely" OOP from the CS introductory curriculum.

Akka Reaches 1.0 Status: Brings the Actor Model to Java and Scala

by Charles Humble on  Feb 16, 2011

Project lead Jonas Bonér has announced today that Akka has reached its 1.0 milestone. InfoQ spoke to Bonér to find out more about the project.

TPL Dataflow – The Successor to CCR

by Jonathan Allen on  Jan 06, 2011

TPL Dataflow is Microsoft’s new library for highly concurrent applications. Using asynchronous message passing and pipelining, it promises to offer more control than thread pools and better performance than manual threading. The downside is that you have to adhere to design patterns that may be unfamiliar to .NET programmers.

Why Microsoft Believes that VB and C# Need an Asynchronous Syntax

by Jonathan Allen on  Jan 04, 2011 2

The new Async CPT for VB and C# looks like it may actually make it into the core language. But with all the emphasis on multi-core systems, why is Microsoft investing so heavily in syntax for designed specifically for making single-threaded asynchronous programming easier?

Sneak Peak: Asynchronous Syntax for Visual Basic and C#

by Jonathan Allen on  Oct 28, 2010 4

In a recent blog post the Visual Basic team let slip an announcement that Visual Basic and C# would be getting a new syntax for asynchronous programming. Built on top of the Task Parallel Library that was introduced in .NET 4, this adds the Async and Await keywords to both languages.

MacRuby Roundup: 0.7 Released, GCD-based Web Server, BridgeSupport

by Werner Schuster on  Oct 24, 2010

MacRuby 0.7 is out, with the usual performance and compatibility improvements, including Ruby 1.9.2 compatibility. To demonstrate MacRuby's tight integration with Snow Leopard's Grand Central Dispatch (GCD), the team has released ControlTower, a Rack-based web server.
