Polyhedral Compiler Technology in Collaboration with Autotuning Important to Domain-Specific Frameworks for HPC

Abstract

Domain-specific frameworks – including embedded domain-specific languages and libraries – increase programmer productivity by encapsulating proven manual optimization strategies into software modules or (semi-)automated tools. In such frameworks, optimizations and optimization strategies capitalize on knowledge of the requirements of a particular application domain to achieve high performance and architecture portability. While many strategies have been used to develop domain-specific frameworks, this position paper argues the importance of polyhedral compiler technology and autotuning for important classes of high-performance computing domains. Such an approach has the following advantages over other strategies: (1) composability; (2) software reuse; and, (3) facilitates performance portability.
