Dynamic Data Mapping

From DoD HPF Training -- 4. HPF Data Mapping Facilities DoD Training and Others -- 1995-98. by Chuck Koelbel -- Rice University
One data mapping is not always appropriate for an entire program
  • Different behavior in different phases
  • ³First sweep in the X dimension, then sweep in the Y dimension²
  • ALLOCATABLE arrays can change size
Therefore, HPF 1.x provides executable DISTRIBUTE and ALIGN
  • Called REALIGN and REDISTRIBUTE
  • DYNAMIC attribute (compare to ALLOCATABLE attribute)
