In this work, we present lfbench: a microbenchmark suite intended as a one-stop shop representing all the popular lock-free data structures. Lock-free programming is very complex and so hard that there hasn’t been a generalized lockfree algorithm designed; instead, lock-free data structures are individually developed and optimized for the specific use-cases. In spite of this difficulty, lock-free programs are indispensable; OS kernel codes, popular databases, networking buffers, and so forth, all rely on lock-free data structures for the performance and scalability they provide. We attempt for the first time to bring all the popular lock-free data structures under one roof, primarily to enable development of new WW semantics needed for easy lock-free programming and help evaluate the same. Additionally, the benchmark suite can be used for:1)Performance analysis of any new S/W algorithms/ libraries developed.2)Building blocks for complex multi-threaded applications.
