This post explores the performance issues that arise when using PLINQ to parallelize queries, and illustrates how the Concurrency Visualizer in Visual Studio 2010 can be a valuable tool in identifying performance bottlenecks and making efficient and profitable...

My name is Mayank Agarwal and I am a Software Developer on the Parallel Computing Platform team.  I obtained my bachelors degree in computer science from the Indian Institute of Technology Delhi and completed my masters and PhD degrees in computer...

One of the samples that is included with the Parallel Programming Samples for .NET 4 is a simple Ray Tracer.  This ray tracer provides a nice visual way of seeing the benefits of .NET 4 parallelism features, as well as giving insights into the way...

Those of you who have been following this blog may have thought “So who are these people anyway?”.  We’ve been writing entries for the last few months and haven’t introduced ourselves.  Where are our manners? We’re now providing brief introductions...
