The High Productivity Computing Systems (HPCS) program seeks a tenfold productivity increase in High Performance Computing (HPC). A change of this magnitude in software development and maintenance demands a transformation similar to other great leaps in industrial productivity. By analogy, this requires a dramatic change to the "infrastructure" and to the(More)
High Performance Foriran (HPF) is anticipated to be an industry-wide standard language portable from workstations to massively parallel supercornputers, implemented by many vendors. Functions needed on the highest-perform ante parallel machines are particularly well-supported in HPF. The definition of HPF, (version 1, completed May 1993) incorporate(More)

In this paper, we showed an eecient algorithm for performing redistribution from cyclic(x) on P processors to cyclic(Kx) on Q processors. The proposed algorithm was represented using generalized circulant matrix formalism. Our algorithm minimizes the number of communication steps and avoids destination node contention in each communication step. The network(More)
