Synchrobench is a benchmark suite for comparing synchronization techniques. It comprises common data structures (e.g., linked list, skip list, hash table, arrays) that implement several abstractions (e.g., set, map, queue). These algorithms are implemented using fine-grained locking (spinlock, mutex), transactional memory (E-STM, TinySTM, SwissTM) or lock-free techniques (compare-and-swap).

• Lock-free algorithms (e.g., harris-michael, fraser's lock-free skip-list).
• Fine-grained locking algorithms (e.g., lazy linked list, optimistic skip list).
• Transactions-based algorithms (e.g., speculation-friendly binary search tree).

Synchrobench is available online at synchrobench.

Synchrobench was formerly called Microbench whose old versions can be found at microbench.
