RMA Process

RMA actions utilize the following fundamental paradigm:

  1. Globally initialize a window for communication
  2. Start an RMA epoch (synchronization)
  3. Perform communication calls as desired
  4. Stop an RMA epoch (synchronization)
  5. Free window and any other resources

The next three topics describe the initialization process, the communication calls, and the three supported synchronization methods.
