Structural Outlooks for the OTIS-Arrangement Network

Recent studies have revealed that the Optical Transpose Interconnection Systems (OTIS) are promising candidates for future high-performance parallel computers. This paper presents and evaluates a general method for algorithm development on the OTIS-Arrangement network (OTIS-AN) as an example of OTIS network. The proposed method can be used and customized for any other OTIS network. Furthermore, it allows efficient mapping of a wide class of algorithms into the OTIS-AN. This method is based on grids and pipelines as popular structures that support a vast body of parallel applications including linear algebra, divide-and-conquer types of algorithms, sorting, and FFT computation. This study confirms the viability of the OTIS-AN as an attractive alternative for large-scale parallel architectures.
