Lockfree hashmap
Witryna18 sie 2024 · This work extends a previous lock-free hash map design to also support lock-free compression. The main goal is to significantly reduce the depth of the internal hash levels within the hash map, in order to minimize cache misses and increase the overall throughput. To materialize our design, we redesigned the existent search, … WitrynaI am trying to design and implement lock-free hashmap using chaining method in C++. Each hash table cell is supposed to contain lockfree list. To enable resizing, my data structure is supposed to contain two arrays - small one which is always available and a bigger one for resizing, when the smaller one is no longer sufficient.

WitrynaLock-free data structures often perform better under scenarios of high contention and when the machine architecture is unknown (and cannot be heavily optimized for). Since we are benchmarking against a general hash table implementation, lock freedom is an ideal approach for our hash table.
