Summary on Grant Application Form |

The role and mechanisms for sharing in parallel programs will be studied from requirements and principles for good practice through design and experiment to investigation of performance-improving transformations. A set of high-level abstractions for sharing data will be defined with two major goals: that the set is sufficiently rich and expressive for usage in practice; and that the abstractions are realisable efficiently on both shared memory and distributed memory MIMD machines. The former will be achieved by studying both the usage of sharing in parallel applications and underlying semantics of abstractions for sharing; the latter will be demonstrated by developing typical implementations, including for distributed networks of workstations. Shared instances of abstract data types (SADTs) will be taken as a starting point. We shall then explore transformation techniques to exploit further the characteristics of particular MIMD machines and optimisations for common patterns of usage of SADTs. A parametric characterisation of the performance attributes of selected MIMD machines will be developed to inform the transformations. Our goal is that the transformation techniques, in combination, produce compiled code with performance that matches that of machine-specific programs.
