Sometimes a group of concurrently running threads may need to rendezvous at a certain point in time before they can further proceed. This situation commonly arises in areas like event simulation, where the events are synchronized via a clock event…
Even though multi-core processors are almost ubiquitous nowadays, applications are slow to catch up. Of course, one could always re-write the applications in order to take the full advantages in a multi-core environment. But it is not an easy undertaking.
Intel’s Integrated Performance Primitives (IPP) is a low level C++ library. It provides routines that are highly optimized on Intel processors. I recently started using it because its vast speed advantage in signal and image processing applications.
In an earlier post, I created a simple prime finding program using Intel’s TBB (Thread Building Block). The main benefit of using TBB is that threading and thread synchronization mechanism are abstracted away within the TBB library so we do…
I have been playing around with Intel’s Threading Building Block for a while and have started to really appreciate its simplicity and elegance: Instead of thinking in threads and thread synchronizations, one can just simply concentrate on the problem on…
In a post (Hyper-Threading and Dual Core Performance Comparison for Computational Intensive Applications) I wrote at the end of last year, I compared multi-threaded scientific application performance of a Pentium 4 processor with hyper-threading enabled and a Pentium D processor,…
Download MPThreadBench.zip There is no doubt that Hyper-Threading can, under certain circumstances, boost application performance.
Most of us know that controls in Windows forms are bound to a specific thread and are not thread safe, and thus UI controls created or referenced on non-UI thread must be marshaled back to the UI thread by using…
