Next: Recognized Externally-Supported HPF Extrinsics
Up: Changes from HPF 1.1
Previous: New Features of HPF 2.0
The Approved Extensions include the following features not part of HPF 1.1:
- Mapping of objects to processor subsets;
- Explicit mapping of pointers and components of derived types;
- New distribution formats: GEN_BLOCK and
INDIRECT;
- New directives: RANGE, SHADOW, ON,
RESIDENT, TASK_REGION;
- Additional intrinsic procedures: ACTIVE_NUM_PROCS,
ACTIVE_PROCS_SHAPE, and a generalized TRANSPOSE
intrinsic;
- New HPF_LIBRARY procedures: HPF_MAP_ARRAY
and HPF_NUMBER_MAPPED; revision of procedures
HPF_ALIGNMENT, HPF_DISTRIBUTION and
HPF_TEMPLATE;
- Support for asynchronous I/O with a new statement WAIT,
and an additional I/O control parameter in the Fortran
READ/WRITE statement;
- Extensions to the EXTRINSIC facilities to support
interoperability with C and FORTRAN 77.
