SBASCO: skeleton-based scientific components

SBASCO is a new programming environment for the development of parallel and distributed high-performance scientific applications. The approach integrates both skeleton-based and component technologies. The main goal of the proposal is to provide a high-level programmability system for the efficient development of numerical applications with performance portability on different platforms. We present the system programming model which considers two different views of a component interface: one from the point of view of the application programmer and another thought to be used by a configuration tool in order to establish efficient implementations. This can be achieved due to the knowledge at the interface level of data distribution and processor layout inside each component. The programming model borrows from software skeletons a cost model enhanced by a run-time analysis, which enables one to automatically establish a suitable degree of parallelism and replication of the internal structure of a component.
