Intel® Fortran Compiler 18.0 Developer Guide and Reference
OpenMP* Fortran Compiler Directive: Specifies that variables are mapped to a device data environment. This directive only applies when targeting Intel® Xeon Phi™ products.
!$OMP TARGET ENTER DATA [clause[[,] clause]... ]
clause |
Is one or more of the following: |
The binding task for the TARGET ENTER DATA construct is the encountering task. TARGET ENTER DATA is a stand-alone directive.
When a TARGET ENTER DATA construct is encountered, the list items in the MAP clauses are mapped to the device data environment according to map-type. A map-type must be specified in all MAP clauses and must be either TO or ALLOC.
The TARGET ENTER DATA construct executes as if it was enclosed in a TASK construct.
When a DEPEND clause is present, it acts as if it appeared on the implicit TASK construct that encloses the TARGET ENTER DATA construct.
If there is no DEVICE clause, the default device is determined by the internal control variable (ICV) named default-device-var.
When an IF clause is present and the IF clause scalar-logical-expression evaluates to .FALSE., the device is the host.
