Web Workers: A Draft Recommendation to Allow Parallelism in Scripts
Posted on http://www.ddj.com/go-parallel
Most modern Web pages run scripts. So far, there are many limitations to allow these scripts to take advantage of multicore microprocessors. However, Web Workers is a draft specification that defines an API to allow Web application authors to spawn background workers running scripts in parallel.

Balder: A Silverlight 3 Managed 3D Engine Optimized for Multicore
Posted on http://www.ddj.com/go-parallel
Silverlight 3 doesn't offer native support for loading and rendering 3D models. However, Balder, an open source project, offers a very complete managed 3D engine for Silverlight 3. It achieved the necessary frame rate taking advantage of Silverlight's threading capabilities.

Parallel Loops Require In-Depth Concurrency Knowledge
Posted on http://www.ddj.com/go-parallel
The new Parallel Extensions offered by .NET Framework 4 Beta 1 present developers the opportunity to use the new parallel loops. Using them, it is easier to distribute tasks in many cores. However, you don't have to forget about concurrency issues.

Tasks Are Not Threads in .NET 4 Beta 1
Posted on http://www.ddj.com/go-parallel
.Net Framework 4.0 with its Parallel Extensions, still in Beta 1, will add the possibility to work with tasks. It is very important to understand that tasks aren't threads. Tasks run using threads. However, it doesn't mean they replace threads.

Keeping Parallelism Balanced is a Must
Posted on http://www.ddj.com/go-parallel
It is very important to optimize applications for existing and forthcoming multicore microprocessors. However, a lack of balance in parallelism levels could lead to explosive parallelism with resulting slowdown rather than speedup.

Using VirtualBox 3.0 Virtualization Software to Measure Multicore Scalability
Posted on http://www.ddj.com/go-parallelThe new Sun's VirtualBox virtualization software release offers very interesting features to allow developers to measure multicore scalability. As these new features were not available in previous versions, it is very important to consider them when evaluating a virtualization solution in order to test parallel performance in different operating systems and hardware environments.

Actors, Messages and Low Lock Contention for Java
Posted on http://www.ddj.com/go-parallel
Using actors and messages, concurrency is easier to understand. However, most developers don't want to learn a new programming language in order to use actors and messages. If you want to forget a bit about threads and locks, you can add nice actor support to an existing Java application using Jetlang.
