A High Throughput B+tree for SIMD Architectures [pdf]
I once needed that thing (with 32-bit integer keys, and either FP32 or FP64 values), but I didn’t want to spend too much time designing novel data structures.
I have copy-pasted B+ tree from TLX https://github.com/tlx/tlx (Boost license), and then I did some local changes to improve the performance for my specific keys and value types. I have used AVX2 intrinsics to improve search within nodes, and I also implemented a few more simple tricks. After these changes, the performance became satisfactory for my application.
