摘要

High-performance scientific computing relies increasingly on high-level large-scale object-oriented software frameworks to manage both algorithmic complexity and the complexities of parallelism: distributed data managpmpnt, process management, inter-process communication, and load balancing. This encapsulation of data management, together with the prescribed semantic-s of a typical fundamental component of such object-oriented frameworks-a parallel or serial array-class library-provides an opportunity for increasingly sophisticated compile-time optimization techniques. This paper describes ROSE, a programmable source-to-source transformation tool for the optimization of C++ object-oriented frameworks. Because it is programmable, explicit knowledge of framework semantics may be exploited; in contrast the potential capability of a general-purpose compiler is limited by computable semantic inference. Since ROSE is programmable, additional specialized program analysis is possible using implicit knowledge of the workings of the framework, for example, dependence analysis at the level of the framework's abstractions. This enables far greater optimization than is even theoretically possible by a general-purpose compiler. ROSE specifically responds to the realization that to achieve acceptable performance, in general it is insufficient to optimize a framework; its use must also be optimized.
