Abstract
Spreadsheets are important business tools. Increasingly they are being used for
simulation e.g. to perform risk analysis. Such tasks have far greater
computational demands than traditional spreadsheet bookkeeping applications. In
this paper we show how spreadsheets can support supercomputing. This is
achieved without requiring the spreadsheet user to have specialist tools or
knowledge. The key technical innovation is a mechanism enabling the concurrent
evaluation of spreadsheet functions. Furthermore the mechanism does not require
modification of the standard spreadsheet evaluation engine.
