E. HPF Local Library

The HPF Local library contains the following routines:

• The routines GLOBAL_ALIGNMENT, GLOBAL_DISTRIBUTION, and GLOBAL_TEMPLATE can be used to query the global mapping of an actual argument while the corresponding HPF routines would return the local mapping that is the trivial one.
• The local library function MY_PROCESSOR returns the identifier P of the calling processor with $0 \le P < NP$ where NP is the number of processors returned by the global HPF_LIBRARY function NUMBER_OF_PROCESSORS.
• ABSTRACT_TO_PHYSICAL
• PHYSICAL_TO_ABSTRACT
• LOCAL_TO_GLOBAL
• GLOBAL_TO_LOCAL
• LOCAL_BLKCNT
• LOCAL_LINDEX
• LOCAL_UINDEX
• GLOBAL_SIZE returns the global size of an actual argument.
