The field of system identification is now a mature one that has evolved over several decades. This has resulted in a suit of well studied and accepted solution techniques. While very effective, these methods have been developed with regard to computing resources that could be considered very modest relative to those available today. This talk is directed at some opportunties for taking advantage of modern advances in computing resources for the solution of system identification problems. These resources can be characterised as offering much enhanced memory and multi-core capacity relative to what was available during the development of the field. The talk will illustrate how taking advantage of these advances can afford solutions to identification problems that would have previously been considered intractable.
