transactional-memory

Software transactional memory (STM) handles concurrent access by executing code blocks atomically, ensuring operations either complete entirely or have no effect, thus preventing race conditions without manual lock management.

To avoid deadlocks in composable concurrency, use software transactional memory instead of traditional locking, enabling safe combination of concurrent operations through transactional variables and retry mechanisms.

To implement an atomic shared counter update using STM, wrap the read and write operations inside a transactional block, ensuring the sequence executes atomically without explicit locks.

Yes, you can synchronize a concurrent cache without explicit locking by applying software transactional memory, allowing multiple threads to read and write entries atomically using composable synchronization primitives.

You should not use STM for parallelism when your workload requires ultra-low latency on highly contended single variables, as transactional memory overhead may exceed the performance of lock-free data structures.
