Language Support for Communicating Transactions A three year PhD position, to start in September 2011, is now available at Trinity College Dublin, Ireland, associated with the project "Language Support for Communicating Transactions" funded by the Microsoft Research PhD Scholarship scheme. Three years fees will be paid at the EU rate and there will be a stipend at the standard HEA rate. The position is based in the Department of Computer Science at Trinity College, co-supervised by Matthew Hennessy at Trinity and Andrew Gordon and Nick Benton at Microsoft Research, Cambridge England. The goal of the project is to develop abstract models and programming support for "communicating transactions" a novel language construct obtained by dropping the standard isolation requirement from traditional transactions. As a result independent transactions can interfere, or communicate, with each other, which leads to complex interdependences in the event of failure. The goal of the project is to construct abstract models for their behaviour and to develop efficient programming language support for these models. Specifically the project will extend concurrent Haskell with a construct for communicating transactions, study the formal semantics of the extended language, investigate efficient implementation strategies, and develop useful programming idioms and verification techniques. Candidates are expected to have a first-class degree in Computer Science. The project will involve language implementation, the elaboration of formal semantics, and the development of verification techniques. Consequently the successful candidate will have a broad range of skills. These should include language implementation skills, a good knowledge of formal techniques for the specification of language semantics; experience with logic based verification techniques is also desirable. Informal preliminary enquiries may be made to Matthew Hennessy at Trinity College.
