It is thread safe for multi-thread use when only one of the threads perform write (update) operations, which allows for lock-free reads provided that the writers are serialized to the Hashtable. To support multiple writers all operations on the Hashtable ...

The hash table exhibits good cache locality. Compared to prior art, our hash table results in 16% and 15% fewer L1 and L2 cache misses respectively, leading to 21% fewer memory stall cycles.

Witryna12 lis 2013 · The traditional way of implementing a hash table is to have an array of linked lists. However, user-space RCU instead uses a split-ordered list, which provides a lock-free RCU-protected resizable hash table. The resulting algorithms are described in the following papers: Ori Shalev and Nir Shavit. Split-ordered lists: Lock-free …

WitrynaLock-free data structures like the Bw-tree [15] (a lock-free B-tree variant) or the Split-Ordered List [19] (a lock-free hash table) do not acquire any locks and therefore generally scale much better than locking-based approaches (in particular for read-mostly workloads). However, lock-free synchronization has other downsides:

WitrynaThe first practical nonblocking hash table was designed by Michael [15], which uses a fixed-size bucket array of lock-free linked lists.
