Course Description (CS5260)

The objective of this course is to learn basic and advanced compiler optimization techniques, either traditional or modern in their scope, or scalar-variable based or loop-optimization based in their application or machine independent or dependent in their variety.

The initial part of the course would be devoted to a collection of traditional and classic compiler analyses and optimizations that are primarily based on control flow and data flow analyses. This would be followed by studying more high-level optimizations that are based on the static single assignment intermediate representation as well as low-level optimizations like register allocation, instruction scheduling and software pipelining.

The latter part of this course would be devoted to a model named polyhedral compilation where for-loops can be transformed to run efficiently on advanced architectures like multi-core or GPU using rational and integer linear programming techniques. Here, the focus would be on basics of the three phase process of dependence analysis, affine scheduling and code generation.

A large part of this course would be about either reading advanced compiler optimization papers, or studying the implementations of optimizations in a compiler like LLVM, or implementing optimizations with a goal of obtaining performance/scalability improvements.

Course Description (CS6300)

This advanced graduate level course is only for invited audience. It will focus on advanced optimization techniques.
