In this entry, I will describe an important parallel programming concept, data parallelism. I will then show data parallelism in action by presenting a simplified implementation of the Jacobi Relaxation algorithm. Data Parallelism In general, data parallelism...

Many of us are aware that caches are our friend, reducing memory latency by exploiting locality . A performance problem known as false sharing can occur in multithreaded scenarios when locality backfires, leading to costly performance degradation. Igor...

In this entry, I will describe how to capture a trace in the middle of a process’ execution for the Concurrency Visualizer, allowing you to visualize the multithreaded behavior of your application during that period of time.  This is accomplished...

Ever wonder how a spellchecker works? How about a parallel spellchecker implemented in PLINQ? Boby George and Pooja Nagpal from the Parallel Computing Platform team wrote this article , which outlines the steps to convert a LINQ implementation of a spellchecker...

Those of you following the various parallel computing blogs from our team or who have played with Visual Studio 2010 have probably noticed a heavy focus on single box parallelism (and mostly on client machines). For a future version of Visual Studio...
