Resource Aware Programming Languages

Catalog description

Resource use—the amount of time, memory, and energy a program requires for its execution—is one of the central subjects of computer science. Nevertheless, resource use traditionally does not play a central role in programming-language concepts, such as operational semantics, type systems, and program logics. This course revisits these concepts to model and analyze resource use of programs in a compositional and mathematically-precise way. The emphasis is on practical, type-based techniques that automatically inform programmers about the resource use of their code. We first study such techniques for functional programs and then develop generalizations to imperative, probabilistic, and concurrent programs.
