What are the three main advantages of a multiprocessor system?
What are the three main advantages of a multiprocessor system?
- Increased throughput, reduced energy consumption, and improved scalability
- Increased throughput, economy of scale, and increased reliability (correct)
- Increased throughput, reduced memory usage, and improved fault tolerance
- Increased throughput, reduced cost, and improved performance
What is the difference between asymmetric multiprocessing and symmetric multiprocessing (SMP)?
What is the difference between asymmetric multiprocessing and symmetric multiprocessing (SMP)?
- Asymmetric uses a single processor, while SMP uses multiple processors
- Asymmetric is more common in small systems, while SMP is more common in large systems
- Asymmetric uses a master processor to schedule and allocate work, while SMP has each processor running an identical copy of the OS (correct)
- Asymmetric is more efficient for parallel processing, while SMP is better for serial processing
