v5.3: 5x Faster Set Intersections with SVE2, NEON, and AVX-512
- Need to accelerate TF-IDF search ranking?
- Joining large tables in an OLAP database?
- Implementing graph algorithms?
Chances are - you need fast set intersections! It's one of the most common operations in programming, yet one of the hardest to accelerate with SIMD! This PR improves existing kernels and adds new ones for fast set intersections of sorted arrays of unique u16 and u32 values. Now, SimSIMD is not practically the only production codebase to use Arm SVE, but also one of the first to use the new SVE2 instructions available on Graviton 4 AWS CPUs, and coming to Nvidia's Grace Hopper, Microsoft Cobalt, and Google Axios! So upgrade to v5.2 and let's make the databases & search systems go 5x faster!
Speedups on x86
The new AVX-512 variant shows significant improvements in pairs/s across all benchmarks:
- For
|A|=128,|B|=128,|A∩B|=1, pairs/s increased- from 1.14M/s in the old implementation
- to 7.73M/s in the new one, a 6.7x improvement.
- At
|A∩B|=64, the pairs/s rose:- from 1.13M/s in the old implementation
- to 8.19M/s in the new one, a 7.2x gain.
- For larger sets, like
|A|=1024and|B|=8192, with|A∩B|=10, pairs/s increased:- from 130.18k/s in the old implementation
- to 194.50k/s in the new one, a 49% gain.
However, in cases like |A|=128, |B|=8192, with |A∩B|=64, pairs/s slightly decreased from 369.7k/s to 222.9k/s. Overall, the new implementation outperforms the previous one, and no case is worse than the serial version.
Speedups on Arm
On the Arm architecture, similar performance gains were achieved using the NEON and SVE2 instruction sets:
- The optimized NEON implementation showed a 3.9x improvement in pairs/s for
|A|=128, |B|=128, |A∩B|=1, going from 1.62M/s to 5.12M/s. - For
|A∩B|=64in the same configuration, performance improved from 1.60M/s to 5.51M/s, showing a 3.4x gain. - The SVE2 implementation also outperformed the previous SVE setup, achieving 5.6M/s (NEON) versus 1.27M/s (SVE) for
|A|=128, |B|=128, |A∩B|=1, a 4.4x improvement. - In larger datasets, such as
|A|=1024and|B|=8192, the pairs/s increased from 49.3k/s to 110.03k/s, with NEON, and further to 109.47k/s with SVE2, nearly doubling the performance.
x86 Benchmarking Setup
The benchmarking was conducted on r7iz AWS instances with Intel Sapphire Rapids CPUs.
