Abstract: 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.
