Horizons of parallel computation

Journal of Parallel and Distributed Computing, 1995
This paper considers the ultimate impact of fundamental physical limitations—notably, speed of light and device size—on parallel computing machines. Although we fully expect an innovative and very gradual evolution to the limiting situation, we take here the provocative view of exploring the consequences of the accomplished attainment of the physical ...

Parallel Prefix Computation

Journal of the ACM, 1980
Summary: The prefix problem is to compute all the products \(x_1\circ x_2\circ \ldots x_k\) for \(i\leq k\leq n\), where \(\circ\) is an associative operation. A recursive construction is used to obtain a product circuit for solving the prefix problem which has depth exactly \([\log_2n]\) and size bounded by \(4n\).

Parallel visual computation

Nature, 1983
The functional abilities and parallel architecture of the human visual system are a rich source of ideas about visual processing. Any visual task that we can perform quickly and effortlessly is likely to have a computational solution using a parallel algorithm. Recently, several such parallel algorithms have been found that exploit information implicit

Parallelism in Seismic Computing

Surveys in Geophysics, 1989
This paper describes a vectorized and parallelized implementation of a two-dimensional pseudo-spectral seismic elastic model and of a (frequency-domain) seismic migration algorithm on the (tightly-coupled) vector multiprocessor IBM 3090 VF. Performance data of alternative parallel implementations on an LCAP (loosely coupled system of array processors ...
