Image Control Statements

Execution of an image control statement divides the execution sequence on an image into segments. The following are image control statements:

A SYNC MEMORY statement is executed for all image control statements except CRITICAL, END CRITICAL, EVENT POST, EVENT WAIT, LOCK, and UNLOCK.

During an execution of a statement that invokes more than one procedure, at most one invocation can cause execution of an image control statement other than CRITICAL or END CRITICAL.

NOTE:

Collective actions may hang if images have stopped or failed and the other images have not all detected the stop or fail; for more information, see FAILED_IMAGES.
