ActiveSheets: Super-Computing with Spreadsheets
نویسنده
چکیده
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.

Spreadsheets for Stream Partitions and Windows
We discuss the suitability of spreadsheet processors as tools for programming streaming systems. We argue that, while spreadsheets can function as powerful models for stream operators, their fundamental boundedness limits their scope of application. We propose two extensions to the spreadsheet model and argue their utility in the context of programming streaming systems. I. STREAM PROCESSING WI...
