Work Stealing Queues in .Net 4 and in Previous Versions

Posted on http://www.ddj.com/go-parallel
.Net 4.0 Beta 1 offers a new and improved thread pool engine. It uses work stealing queues to provide nice load-balancing capabilities, better performance and greater scalability. The work stealing mechanism allows you to reduce the scheduling overhead in highly parallelized algorithms.

Challenges in Multi-Core Era – Part 2

Previously I talked about the evolution of microprocessors and specialized hardware since the wide-spread adoption of multi-core began a few years ago. In this second part to Challenges in Multi-Core Era, I’ll compare the multi-core capabilities across today’s popular operating systems.

Challenges in Multi-Core Era – Part 1

A few years ago, in 2005, Herb Sutter published an article in Dr. Dobb’s Journal, “The Free Lunch Is Over: A Fundamental Turn Toward Concurrency in Software”. He talked about the need to start developing software considering concurrency to fully exploit continuing exponential microprocessors throughput gains.
Here we are in year 2009...

Alternatives for Parallelizing Legacy Serial Code

Posted on http://www.ddj.com/go-parallel
Applications developed using modern programming languages can become legacy code faster than expected. Multicore microprocessors have been found guilty of transforming outstanding serial code into legacy code in just a few years. However, there are many alternatives to translate multicore power into application performance making small changes to the legacy serial code.

New Garbage Collectors Designed With Parallelism in Mind

Posted on http://www.ddj.com/go-parallel
On the one hand, Garbage Collectors simplify developers' lives, but on the other hand, they can become the greatest enemies of a parallelized algorithm's performance. Finally, Java 7 and .Net 4 are going to offer new Garbage Collectors really targeted for multicore microprocessors with large memories.
