Aspects of unbounded parallelism
- 149 Downloads
The parallel program schemata, introduced by Karp and Miller , are considered for an unbounded number of operations and their decidability, result for determinacy is extended to this case under certain restrictions on the nature of the conflicts. The work of Keller  on maximal parallelism is discussed and an alternative approach to this problem is proposed which leads to a simple and fast solution algorithm for the general scheduling problem for unbounded parallelism. In contrast to this the general scheduling problem for bounded parallelism is NP-complete as proven in Ullman .
