Question 22
Explanation
- SMP is a multi-processing system where multiple processors share common operating system and memory.
- Processors also share disk input/output resources.
- The processors also share memory and the I/O bus or data path.
- OS manages scheduling on all the processors- combines power of multiple processors to complete a process.
- Primarily used in resource intensive computing environments.
Multiple Processors Are Transparent to the User
- These processor share main memory and I/O facilities.
- All processors can perform the same functions.
Advantages of SMP
- Performance:
- Allows parallel processing
- Availability:
- Failure of a single processor does not stop computing.
- Incremental growth:
- Additional processors can be added.
