In the book "Advanced computer architecture and parallel processing" (El-Rewini & Abd-El-Barr), there is a question in the exercises of chapter 1 that needs the reader to compare between multiprocessor systems and uniprocessor systems in terms of many factors including run-time system:
Compare uniprocessor systems with multiprocessor systems for the following aspects:
- Ease of programming;
- The need for synchronization;
- Performance evaluation; and
- Run-time system.
I know how to compare between these two systems in terms of the other factors (ease of programming, need for synchronization, and performance evaluation) but I can't to compare between them in terms of run-time system as I don't know what is the exact meaning of run-time system?
