Feature: How is WASM Compiled? Are you using wasm_simd128 and msimd128 ?

Here's where the NGT algorithm, which is faster than HNSW, uses SIMD to optimize internally: https://github.com/yahoojapan/NGT/blob/1e44fffc2b95b211ff29ee693abb4a25057042d4/lib/NGT/Clustering.h#L224

Hi @vtempest! We don't currently compile to WASM, but it should be compatible with SimSIMD NEON kernels, I believe. What exactly are you looking for?

[vtempest]

I would like to help build the fastest Simd accelerated vector search. If usearch uses simsimd and compiles to wasm, I'd love to improve upon it and build my vsearch fork with ram limited clusters.

[ashvardanian]

Yes, USearch compiles to WASM, but the whole ecosystem is currently fragmented, and it's not clear how to ship library dependencies for WASM. Still, it shouldn't be hard to integrate USearch directly into an arbitrary project that uses WASM, and then compile together as a monorepo. Have you tried that?

[vtempest]

Yes I was working on top of the original hnswlib ported to wasm here: https://github.com/kaiobarb/hnswlib-wasm?tab=readme-ov-file
I am wondering how to integrate usearch instead as the base lib and then add to it the cluster splitting for RAM limits.

NGT inventor says my ram-limited clusters approach looks very promising. I'd like to integrate it into hnsw and usearch v3
