For any of these one-sided communication calls, we can choose among three different synchronization methods, each of which has its own syntax and requirements. This topic discusses the synchronization options in more detail.
Objectives
After you complete this topic, you should be able to:
- List the three synchronization patterns
- Explain the fence synchronization pattern
- Explain the post-start-complete-wait pattern
