Abstract

The invention provides a mechanism for allowing a share memory/parallel processing architecture to be used in place of a conventional uni-processing architecture without requiring code originally written for the conventional system to be rewritten. Exclusive Access and Shared Read Access implementations are provided. A rollback mechanism is provided which allows all the effects of a task to be undone.
