Introduction to the JPDC Special Issue on Domain-Specific Languages and High-Level Frameworks for High-Performance Computing

摘要

Multi-level heterogeneous parallelism and deep memory hierarchies in current and emerging computer systems make programming for high-performance applications especially difficult. The task is made even more challenging by the changing landscape of system architecture mandated by power and micro-architecture considerations. Domain-specific languages (DSLs) and high-level frameworks (HLFs) provide convenient abstractions, shielding application developers from much of the complexity and variability of explicitly programming in standard programming languages such as C, C++, and Fortran. Effective design of such abstractions for high-performance computing requires close interaction between researchers developing these languages and frameworks and domain experts with a profound understanding of the problem to be solved. This special issue contains six articles related to the design and evaluation of DSLs and HLFs used to construct specific applications and broaden classes of computation idioms.
