Welcome to the JVSTM project

The JVSTM (Java Versioned STM) is a Java library implementing our approach to STM (Software Transactional Memory), which introduces the concept of versioned boxes.

The Java Versioned Software Transactional Memory (JVSTM) is a pure Java library implementing an STM (1). JVSTM introduces the concept of versioned boxes (2), which are transactional locations that may be read and written during transactions, much in the same way of other STMs, except that they keep the history of values written to them by any committed transaction.

Since version 2 the JVSTM implementation is entirely non-blocking (3).
