Image Control Statements
Execution of an image control statement divides the execution sequence on an image into segments. The following are image control statements:
The SYNC ALL statement
The SYNC IMAGES statement
The SYNC MEMORY statement
The SYNC TEAM statement
An ALLOCATE or DEALLOCATE statement that has a coarray allocatable object
The CHANGE TEAM and END TEAM statements
The CRITICAL and END CRITICAL statements
The EVENT POST and EVENT WAIT statements
The FORM TEAM statement
The LOCK and UNLOCK statements
Any statement that completes execution of a block or procedure and which results in the implicit deallocation of a coarray
A CALL statement that references the intrinsic subroutine MOVE_ALLOC with coarray arguments
The STOP statement
The END statement of a main program
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.
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.
