Matrix triangularization on a MIMD computer.
Proc. 9th IASTED Int'l Symp. Applied Informatics, pp.48-50, Innsbruck, Austria, February 18-21, 1991.

Gaussian eliminations and Givens transformations were used as an example of matrix triangularisation in the paper. For a sequential version of every algorithm was constructed an associated task graph. Parallel algorithms with quadratic time complexity were designed by assigning tasks to processors according to the precedence constraints.
