主 题:Parallel Algorithms Least Squares Fitting
摘 要:The rational and suitability of implementing model fitting algorithms on vector and parallel computers are discussed. A particular maximum likelihood based algorithm for fitting of two-dimensional Gaussian peaks was investigated in detail and adapted to a system of four transputers. Analysis of the algorithm shows it well suited to both vectorisation and parallelisation;this result being applicable to other fitting methods. The transputer implementation gave an increase in performance (5-10 times faster) compared to the host computer, allowing the model fitting procedure to approach acceptable response times.
