Explicit Replication Using Templates

If an array is not explicitly distributed it is given the default mapping. This is often, but not always, replication. It is often prudent to explicitly replicate objects if this is what is desired.

To force replication of an array, A:

• declare a template to be the same size as the processor grid,
• align A with each template element,
• distribute the template

For example,

      REAL, DIMENSION(100,100)   :: A
!HPF$ PROCESSORS, DIMENSION(NUMBER_OF_PROCESSORS()) :: P
!HPF$ TEMPLATE, DIMENSION(NUMBER_OF_PROCESSORS())   :: T
!HPF$ ALIGN A(*,*) WITH T(*)
!HPF$ DISTRIBUTE (BLOCK) :: T
