What is the primary purpose of dividing work among processes/threads in parallel programs?
What is the primary purpose of dividing work among processes/threads in parallel programs?
- To minimize synchronization between processes/threads
- So each process/thread gets roughly the same amount of work (correct)
- To maximize communication between processes/threads
- To allocate work based on the speed of each process/thread
What does SPMD stand for?
What does SPMD stand for?
- Single Program Multiple Data (correct)
- Sequential Program Multiple Devices
- Synchronized Parallel Memory Distribution
- Shared Process Memory Distribution
What is the key aspect of writing parallel programs to minimize communication?
What is the key aspect of writing parallel programs to minimize communication?
- Using multiple processes for shared memory programs
- Dividing the work so each process/thread gets roughly the same amount (correct)
- Minimizing the number of conditional branches
- Increasing synchronization between processes/threads
