Suppose you have an array of 1000 random integer numbers and you need to loop over it to find the number 68 for example. Using the new Parallel.For on a quad core CPU would improve speed considera...

As software gets more and more concurrent, how do you handle testing the core behaviour of the type with your unit tests (not the parallel behaviour, just the core behaviour)? In the good old days...

I am new to C#, Parallel.ForEach, and .NET in general. I want to parallelize a search that involves thousands of locations. For each location, I compute great circle distance. That is a calculation...

I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread local storage might be sensible to allow re-use of objects by worker threads. As such I was look...

The problem Although the code about which I will talk here I wrote in F#, it is based on the .NET 4 framework, not specifically depending on any particularity of F# (at least it seems so!). I hav...

I'm looking for a simple implementation of a parallelized (multi-threaded) sort algorithm in C# that can operate on List<T> or Arrays, and possibly using Parallel Extensions but that part isn...

At least since the release of .NET 4.0, Microsoft seems to have put a lot of effort in support for parallel and asynchronous programming and it seems a lot of APIs and libraries around this have em...

Parallel.ForEach Not Spinning Up New Threads Hello all, we have a very IO-intensive operation that we wrote using Parallel.ForEach from Microsoft's Parallel Extensions for the .NET Framework. We n...

I have a Parallel.ForEach loop running an intensive operation inside the body. The operation can use a Hashtable to store the values, and can be reused for other consecutive loop items. I add to t...
