MSEPT'12 - Conference on Software Engineering for Multicore Systems
It is hard to leverage the parallelism provided by recent processor architectures. As these CPUs are now available even in the low cost price sector, the main challenge of software engineers is to utilize the processors in their applications or apps. The International Conference on Multicore Software Engineering, Performance, and Tools (MSEPT'12) will focus on possible answers.

Explaining .NET’s Barrier Class
With the increased emphasis on multi-core systems an understanding of parallel and concurrent programming is more important than ever. Fortunately .NET 4 has made a lot of advances in the types of synchronization primitives available to developers. One such primitive is the Barrier, which Emad Omara uses to implement a parallel merge sort.
