Atomic

We are investigating issues related to software transactions, a concurrency primitive that is easier-to-use and harder-to-implement than locks. Our work has considered language design, semantics, (software) implementation, and evaluation (for reliability and performance).

Relevant publications:

• High-Level Small-Step Operational Semantics for Transactions (POPL 2008)
      Katherine F. Moore and Dan Grossman
  Note: An earlier version was presented informally at TRANSACT 2007.
• Software Transactions Meet First-Class Continuations (SCHEME 2007)
      Aaron Kimball and Dan Grossman
• The Transactional Memory / Garbage Collection Analogy (OOPSLA 2007)
