This video shows the difference between using one core and four cores in a highly threaded, parallelized application programmed in Visual C# 3.0 (2008).

In order to solve problems that arise in concurrently running threads in applications, we need new debugging techniques suitable for the new parallelism environments that occur in Visual C#. Multicore programming and parallel programming require new debugging techniques.
Learn some tricks to prepare multithreaded code to simplify the debugging and troubleshooting processes.

Sometimes, you don’t want to use all the available cores in a parallel loop. Why? Because you have better plans for the remaining available cores. Thus, you want to specify the concurrency level of a parallel loop. Luckily, Task Parallel Library Beta 1 will allow you to do this using the new ParallelOptions class.

As C# and Visual Basic (in the .Net world) and Java are high level programming languages, most developers were not used to check for some hardware information. With multicore microprocessors and a task-oriented programming model, trying to take full advantage of parallel processing capabilities offered by modern microprocessors, this is changing.

Management professionals love metrics. However, they don’t like the idea to optimize applications that are currently running. Thus, what about showing them some metrics about the power that they are wasting using a free tool?

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.

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.

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

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.

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.
