The COMMIT Group

About Us

Commit (Compilers at MIT) is a research group led by Professor Saman Amarasinghe in the CSAIL research lab at MIT. The primary motivation of the Commit group is to discover novel approaches to improve the performance of modern computer systems without unduly increasing the complexity faced by application developers, compiler writers, or computer architects.
