Multiple Processors Scheduling in Operating Systems Quiz

What is the main focus of multiple processor scheduling?

• Increasing the speed of a single processor

• Designing a single processor system

• Managing multiple processors in a system

• Reducing memory usage

What is processor affinity?

• The method of balancing loads across processors

• The requirement for a process to run on multiple processors

• The tendency of a process to run on the same processor

• The ability of a process to run on any processor

Which of the following describes symmetric multiprocessing?

• One processor handles all scheduling decisions

• Each processor has its own scheduling mechanism

• All processors share a common ready queue

• Processors are not connected to a common bus

What is the purpose of load balancing in an SMP system?

• To increase the number of processors

• To keep workloads evenly distributed across processors

• To reduce the number of processes

• To eliminate the need for a master server

What is the difference between soft affinity and hard affinity?

• Soft affinity is used in asymmetric multiprocessing

• Hard affinity is not implemented in Linux systems

• Hard affinity allows a process to specify a subset of processors

• Soft affinity guarantees a process will run on the same processor

What is coarse-grained multithreading?

• Switching threads only during long latency events

• Running multiple threads simultaneously on one core

• A method to increase cache memory

• Switching threads at the instruction cycle level

What is the main characteristic of asymmetric multiprocessing?

• All processors share the same cache

• Each processor has its own operating system

• One processor handles all scheduling and I/O processing

• All processors are identical

What does the term 'memory stall' refer to?

• A type of processor scheduling

• A situation where all processors are busy

• A delay caused by a processor waiting for data

• A method of managing memory allocation

What is the role of a master server in asymmetric multiprocessing?

• To manage all scheduling decisions

• To handle memory management

• To execute user processes

• To balance loads across processors

What is the main advantage of multi-core processors?

• Higher power consumption

• Simpler scheduling problems

• Faster processing and lower power usage

• Increased physical size of the processor
