What is the main advantage of the Distributed Memory model over the Shared Memory model?
What is the main advantage of the Distributed Memory model over the Shared Memory model?
- It is less expensive to design and produce distributed memory machines
- Increasing the number of processors also increases the size of the memory proportionately (correct)
- Processor communication is faster in the Distributed Memory model
- Data races and deadlocks can be avoided during programming
Which of the following is a disadvantage of the Distributed Memory model?
Which of the following is a disadvantage of the Distributed Memory model?
- Distributed memory machines are more complex and expensive to design and produce
- Each processor can rapidly access its own memory without affecting the other processors' memory
- Increasing the number of processors also increases the size of the memory proportionately
- The programmer is responsible for establishing communication between processors (correct)
