Question about Project: Posting list encoding improvements
...ploit SIMD instructions in
PFORDelta. It is fast and can achieve good compression ratio. Recently, I
also did some experiments to test the state-of-the-art and proposed
encoding algorithms of posting lists. We used our own search engine called
PARADISE and the datasets are GOV2(25 million docs) and ClueWeb09B(50
million docs). Below is some experimental results of docIDs? gap sequence
on ClueWeb09B, which is similar to Lemire's results[1] (The implementation
of SIMD_pfor_delta is somewhat different to that in Lemire's paper):
Algorithm Name
Compression Speed(M/s)
Decompression Speed(M/s)
