Latest Patents

Among his most recent contributions, Detlefs has developed a **Software Transactional Memory** system that introduces a lightweight key-based action framework. This framework comprises a set of unified application programming interfaces (APIs) available through an STM library, enabling clients to register, query, and update actions with specific keys within transactional memory code. Each action is designed to incorporate a key, state information, and a series of callbacks that enhance the validation, commit, abort, and re-execution phases of transaction execution. These actions extend the built-in concurrency controls of the STM system, facilitating customized control logic, supporting transaction nesting semantics, and integrating with garbage collection systems.

Another notable patent addresses **Parallel Nested Transactions in Transactional Memory**. This patent reveals various technologies for managing multiple closed nested transactions under a single parent transaction, executed concurrently. The methods ensure that the effects of these nested transactions remain hidden from outside transactions until the parent transaction is committed, thereby maintaining consistency and reliability.
