Distributed and Parallel Operating Systems

• Facilitate use of geographically distributed resources.
• Supports communication between a job or between different jobs.
• Information sharing is of most significance.
• Support for parallel applications wishing to obtain speedup of computationally intensive tasks.
• Supports synchronisation of activities to coordinate sharing of information.
• Use of primitives defined within OS, such as RPC (Remote Procedure Call) to support distributed activities.
• Efficient Communication primitives between activities also supported.
