This paper describes a methodology that provides detailed predictive performance information throughout the software design and implementation cycles. It is struc-tured around a hierarchy of performance models that describe the computing system in terms of its software, parallelization, and hardware components. The methodology is illustrated with an initial(More)
This paper describes a toolset, PACE, that provides detailed predictive performance information throughout the implementation and execution stages of an application. It is structured around a hierarchy of performance models that describes distributed computing systems in terms of its software, parallelisation and hardware components, providing performance(More)
The development of efficient software for high performance systems requires a number of decisions to be made by software developer. These may include selecting a parallelisation strategy, data mapping, system configuration, and other critical parameters. This selection is typically a complex procedure and takes place based on the intuition of the(More)
There is a wide range of performance models being developed for the analysis of present and future generation systems. A major concern in using these models however, is the provision of realistic application workload information. There is a need for a common interface that couples generic workload information to the underlying hardware characteristics. In(More)
