Oracle computations in parallel numerical linear algebra

Theoretical Computer Science, 1994
Using a new notion of reducibility, the authors investigate the behaviour of several known reductions among important problems in linear algebra. The main concern is the relative parallel-time complexity of certain problems within the class NC. It is shown that, within the computational model considered, many known reduction algorithms do not extend ...
