READ-ONLY COMMUNICATION OPERATOR

摘要

A high level programming language provides a read-only communication operator that prevents a computational space from being written. An indexable type with a rank and element type defines the computational space. For an input indexable type, the read-only communication operator produces an output indexable type with the same rank and element type as the input indexable type but ensures that the output indexable type may not be written. The read-only communication operator ensures that any attempt to write to the output indexable type will be detected as an error at compile time.

1. A system comprising:
processing elements; and memory to store computer executable instructions to control the processing elements to:
apply a read-only communication operator, in a data parallel source code configured to execute on one or more data parallel compute nodes, to an input indexable type to generate an output indexable type to form an immutable computational space, the read-only communication operator defines only constant index operators and subscript operators for the output indexable type; andperform a data parallel algorithm using the output indexable type.
