Addressing the Challenges of Multicore Software

Multicore processor solutions such as the ARM11 MPCore and Cortex-A9 MPCore processors provide a flexible and energy-efficient way to dramatically increase processing power. The availability of software capable to efficiently handle and exploit the benefits of a multicore system has become increasingly important due to the uptake of such solutions in the industry. Expressing concurrency does not need to be hard: The focus is on ensuring that an optimal use of multiple cores is achieved, avoiding common pitfalls and making the right choice of parallelisation policy, as explored in this article.
