Abstract

Embodiments of the invention involve a method of concurrent processing of chain calculations using multiple processors each having a separate recalculation engine in a spreadsheet program. The operations basically include first determining a number of available processors, then allocating a recalculation engine to each available processor, distributing the formulas between the recalculation engines, and then concurrently evaluating the formulas distributed to each recalculation engine when a recalc operation is called for in the spreadsheet program.
