Invoking parallel tasks

Posted on Intel Software Network
In a recent post, Robert Chesebrough (Intel) talked about less focus on threads and more focus on tasks. I agree with him. I do believe that decomposing the job to be done into many tasks is the key to a successfully parallelized algorithm.

Using Intel Concurrency Checker 2.1 to benchmark threading and multicore metrics

This video uses Intel Concurrency Checker 2.1 to benchmark threading metrics on a parallelized and multithreaded C# application. Watching this video you will find out that there is an easy to use utility to test multicore optimizations in any executable.

For more information about Intel Concurrency Checker 2.1, visit: http://software.intel.com/

The application also uses AForge.NET imaging framework. For more information about AForge.NET, visit: http://www.aforgenet.com

Parallel Extensions offer backward compatibility

Posted on Intel Software Network
Many developers are working with the features offered by C# 3.0 and .Net 3.5 to exploit multi-core CPUs. Parallel Extensions, which will be part of .Net 4.0 in Visual Studio 2010 are entering Beta 1. Luckily, they will offer backward compatibility.
Parallel Extension will offer a lot of interesting features related to multi-core programming. So, developers face many questions.

Intel's Hyper-Threading Strikes Back

Intel's Hyper-Threading technology was introduced with the 3.06 GHz Pentium 4 microprocessor. A few years later, the new Intel Core i7 processors offer Hyper-Threading again.

Novell's Mono brings SIMD support to C#

Parallel programming is not just about multi-threading and multi-core. There's also a lot of power in the SIMD (Single Instruction Multiple Data) extended instruction set available in most modern microprocessors from Intel and AMD.
