Presentation / Conference Contribution
Chutimaskul, W., & Kerridge, J. (1994, October). Generic Matrices in occam3(e). Presented at NATUG-7: Seventh Conference of the North American Transputer Users Group, Atlanta, GA

The possibility of enhancing the occam3 type system to support genericity for the purpose of reusability can be realised by means of user-defined parameterised types (UPTs) and overloading. A UPT is a mechanism for the reuse of data types and is empl... Read More about Generic Matrices in occam3(e).

A strategy for semantic integrity enforcement in a parallel database machine (1994)
Presentation / Conference Contribution
McCarroll, N., & Kerridge, J. (1994, July). A strategy for semantic integrity enforcement in a parallel database machine. Presented at Directions in Databases: 12th British National Conference on Databases, BNCOD 12, Guildford, UK

Semantic integrity constraints represent knowledge about data with which a relational database must be consistent. To enforce semantic integrity we must ensure that transactions which alter the database will preserve database consistency by accompany...

An Appreciation of the Subtleties of Shared Channels in occam3 (1993)
Presentation / Conference Contribution
Waithe, S., & Kerridge, J. (1993, March). An Appreciation of the Subtleties of Shared Channels in occam3. Presented at 16th World occam* and Transputer User Group Technical Meeting (WoTUG-16), Sheffield, UK

By exploiting virtual channels implemented on the INMOS T9000 transputer, occam3 offers the facility of sharing. This allows us to declare a channel as SHARED which then allows an arbitrary number of processes to communicate across this channel. By m...
