A parallel intermediate representation based on Lambda expressions

The lambda calculus has frequently been used as an intermediate representation for programming languages, particularly for functional programming language systems. We introduce two simple extensions to the lambda calculus that describe potentially parallel computations. These extensions permit us to use the lambda calculus as an intermediate form for languages that operate on large data items as single entities, such as FP or APL. We conclude by discussing how this intermediate representation can facilitate the generation of code for different types of parallel systems
