University Gives Java Parallelism a Boost

InfoWorld (12/17/10) Paul Krill

University of Illinois at Urbana-Champaign (UIUC) computer scientists recently released DPJizer, an interactive tool designed to simplify the writing process in Deterministic Parallel Java (DPJ), a Java-based type-and-effect system developed by the university earlier this year. The developers say the DPJizer Eclipse plug-in is the first interactive, practical type-and-effect inference tool for a modern object-oriented system. DPJizer can save time by automatically analyzing a whole program with DPJ annotations. “DPJizer increases the productivity of programmers in writing safe and deterministic-by-default parallel programs for multi-core systems,” says UIUC’s Mohsen Vakilian. The goal of the DPJ project is to provide deterministic-by-default semantics for an object-oriented, imperative parallel language using mostly compile-time checking. The system also features a compiler, runtime, and other components of open source software.
