Welcome to HyFlow^TM

The HyFlow^TM project is developing distributed transactional memory (or DTM) as an alternative to lock-based distributed concurrency control. HyFlow is a framework for DTM, with pluggable support for policies for directory lookup, transactional synchronization and recovery, contention management, and cache coherence. HyFlow exports a distributed programming model that excludes locks: using (Java 5’s) annotations, a programmer can define atomic sections as transactions, in which reads and writes to shared, local and remote objects appear to take effect instantaneously. No changes are needed to the underlying virtual machine or compiler.
