Q. Example on Distribution of Data?

!HPF$ PROCESSORS P1(4)

!HPF$ TEMPLATE T1(18)

!HPF$ DISTRIBUTE T1(BLOCK) ONTO P1 

Consequently of these instructions distribution of data would be as displayed in Figure below.

Figure: Block Distribution of Data

In a alternative of block distribution the number of template elements assigned to every processor may be explicitly specified as in 

!HPF$ DISTRIBUTE T1 (BLOCK (6)) ONTO P1

Distribution of data will be as displayed in Figure below.

Figure: Variation of Block Distribution

It means we assign all template elements before exhausting processors and some processors are left empty.

(b) Cyclic Distribution

Simple cyclic distribution is specified by 

!HPF$ DISTRIBUTE T1(CYCLIC) ONTO P1

The first processor gets first template element and second gets second and so on. When a set of processors is exhausted go back to first processor and carry on allocating template elements from there.
