context -- the component of a shape that designates the active positions of a parallel operand.
dimension -- the number of positions along an axis of a shape.

element -- the value or object at a position within a parallel operand, respectively; or a member of an array.
elemental execution -- execution of a function or operation on elements within corresponding active positions of parallel operands.
layout -- information specifying a distribution of a parallel object or parallel value onto memory.
node -- an actual processing unit in the execution environment.
parallel indexing -- selecting elements of a parallel operand; single elements or multiple elements may be selected.
parallel object -- a structured collection of one or more identically-sized objects where the structure is defined by a shape.
parallel operand -- parallel value or parallel object.
parallel pointer -- a parallel operand whose element type is pointer type.
parallel lvalue -- a structured collection of one or more identically-typed values where the structure is defined by a shape.
physical -- a predefined variable of type shape which is of rank 1 and dimension equal to the number of nodes in the execution environment.
pointer to parallel -- a pointer type whose referenced type is a parallel type.
position -- a point within the index space defined by the Cartesia product of the dimensions of a shape.
rank -- the number of dimensions or axes in a shape.
reduction -- an operation that when applied to a parallel operand produces a single, nonparallel value, such as the sum of all the elements of a parallel object.
shape -- a type whose values consist of the following components: rank, dimensions, layout, and context.
