Introduction to the computing special issue: performance portability and tuning for multi-core and many-core computing systems

摘要

The pervasiveness of homogeneous and heterogeneous multi-core and many-core processors, in a large spectrum of systems from embedded and general-purpose to high-end computing systems, poses major challenges to software industry. In general, there is no guarantee that software developed for a particular architecture will be executable (that is functional) on another architecture. Furthermore, ensuring that the software preserves some aspects of performance behavior (such as temporal or energy efficiency) across different such architectures is an open research issue. Therefore, this special issue focuses on novel solutions for functional and performance portability as well as automatic tuning across different architectures.
