ATOMIC_ADD— Atomic ADD operation
ATOMIC_ADD(ATOM, VALUE)atomically adds the value of VAR to the variable ATOM. When STAT is present and the invokation was successful, it is assigned the value 0. If it is present and the invokation has failed, it is assigned a positive value; in particular, for a coindexed ATOM, if the remote image has stopped, it is assigned the value of
STAT_STOPPED_IMAGEand if the remote image has failed, the value
CALL ATOMIC_ADD (ATOM, VALUE [, STAT])
|ATOM||Scalar coarray or coindexed variable of integer
type with |
|VALUE||Scalar of the same type as ATOM. If the kind
is different, the value is converted to the kind of ATOM.
|STAT||(optional) Scalar default-kind integer variable.
