abstract

The virtual array software allows you to program with virtual arrays, that is
arrays with dimensions that exceed the physical dimensions of the MasPar.
For example, the machine may be configured with an array of 128 by 128
processing elements, while the virtual array is defined to be 512 by 512
elements.

The virtualization is accomplished by means of a preprocessor. After
preprocessing a source file containing directives for virtualization, an mpl
source file is produced. Thus the preprocessor simply relieves the
programmer of the tedious task of coding the loop structures needed to
process plural arrays whose sizes are multiples of the physical array size.
