Modern multicore and manycore systems offer impressive performance for various applications. However, achieving this performance is a challenging task. While multicore and manycore processors alleviate several problems that are related to single-core processors - known as memory wall, power wall, or instruction-level parallelism wall - they raise the issue of the programmability wall. The multicore and manycore programmability wall calls for new parallel programming methods and tools. Therefore, this topic focuses on novel solutions for efficient programming of multicore and manycore processors in the context of general-purpose and embedded systems.
