Implementing Linda Tuplespace on a Distributed System

Linda, a general purpose coordination language, has been used to make a language parallel. Based on a logically shared tuplespace, Linda poses difficulties to be efficiently implemented on a distributed multiprocessor system. This paper reports our approach to solve the problem: processors are divided into groups, and each group has a group manager to provide a local view of the global tuplespace, and handles the tuplespace operations incurred by processors within the group. To maintain the consistency and correctness of the Linda tuplespace operations, we propose the algorithms of a group manager. We also implement the algorithms on a transputer-based multicomputer and show the experiment results.
