System and Method for Communication Between Concurrent Transactions Using Transaction Communicator Objects

Transactional memory implementations may be extended to include special transaction communicator objects through which concurrent transactions can communicate. Changes by a first transaction to a communicator may be visible to concurrent transactions before the first transaction commits. Although isolation of transactions may be compromised by such communication, the effects of this compromise may be limited by tracking dependencies among transactions, and preventing any transaction from committing unless every transaction whose changes it has observed also commits. For example, mutually dependent or cyclically dependent transactions may commit or abort together. Transactions that do not communicate with each other may remain isolated. The system may provide a communicator-isolating transaction that ensures isolation even for accesses to communicators, which may be implemented using nesting transactions. True (e.g., read-after-write) dependencies, ordering (e.g., write-after-write) dependencies, and / or anti-dependencies (e.g., write-after-read dependencies) may be tracked, and a resulting dependency graph may be perused by the commit protocol.
