Granularity
- Very Coarse Grain: When synchronization needs are not high among parallel processes.
- Processes can even be distributed across network.
- Example: CORBA standard for distributed system.
- Independent parallelism: Multiple unrelated processes.
- All independent processes can run in parallel.
Design Issues
- Where does the OS run?
- Mapping processes to processors.
- Use of multiprogramming on individual processors.
- Actual dispatching of a process.
