SimSIMD 📏

Computing dot-products, similarity measures, and distances between low- and high-dimensional vectors is ubiquitous in Machine Learning, Scientific Computing, Geo-Spatial Analysis, and Information Retrieval.
These algorithms generally have linear complexity in time, constant complexity in space, and are data-parallel.
In other words, it is easily parallelizable and vectorizable and often available in packages like BLAS and LAPACK, as well as higher-level numpy and scipy Python libraries.
Ironically, even with decades of evolution in compilers and numerical computing, most libraries can be 3-200x slower than hardware potential even on the most popular hardware, like 64-bit x86 and Arm CPUs.
SimSIMD attempts to fill that gap.
1️⃣ SimSIMD functions are practically as fast as memcpy.
2️⃣ SimSIMD compiles to more platforms than NumPy (105 vs 35) and has more backends than most BLAS implementations.

Features
SimSIMD provides over 100 SIMD-optimized kernels for various distance and similarity measures, accelerating search in USearch and several DBMS products.
Implemented distance functions include:

Euclidean (L2) and Cosine (Angular) spatial distances for Vector Search.
Dot-Products for real & complex vectors for DSP & Quantum computing.
Hamming (~ Manhattan) and Jaccard (~ Tanimoto) bit-level distances.
Kullback-Leibler and Jensen–Shannon divergences for probability distributions.
Haversine and Vincenty's formulae for Geospatial Analysis.
For Levenshtein, Needleman–Wunsch and other text metrics, check StringZilla.

Moreover, SimSIMD...

handles f64, f32, and f16 real & complex vectors.
handles i8 integral and b8 binary vectors.
is a zero-dependency header-only C 99 library.
has bindings for Python, Rust and JavaScript.
has Arm backends for NEON and Scalable Vector Extensions (SVE).
has x86 backends for Haswell, Skylake, Ice Lake, and Sapphire Rapids.

Due to the high-level of fragmentation of SIMD support in different x86 CPUs, SimSIMD uses the names of select Intel CPU generations for its backends.
They, however, also work on AMD CPUs.
Intel Haswell is compatible with AMD Zen 1/2/3, while AMD Genoa Zen 4 covers AVX-512 instructions added to Intel Skylake and Ice Lake.
You can learn more about the technical implementation details in the following blog-posts:

Uses Horner's method for polynomial approximations, beating GCC 12 by 119x.
Uses Arm SVE and x86 AVX-512's masked loads to eliminate tail for-loops.
Uses AVX-512 FP16 for half-precision operations, that few compilers vectorize.
Substitutes LibC's sqrt calls with bit-hacks using Jan Kadlec's constant.
For Python avoids slow PyBind11, SWIG, and even PyArg_ParseTuple for speed.
For JavaScript uses typed arrays and NAPI for zero-copy calls.

Using SimSIMD in Python
The package is intended to replace the usage of numpy.inner, numpy.dot, and scipy.spatial.distance.
Aside from drastic performance improvements, SimSIMD significantly improves accuracy in mixed precision setups.
NumPy and SciPy, processing i8 or f16 vectors, will use the same types for accumulators, while SimSIMD can combine i8 enumeration, i16 multiplication, and i32 accumulation to avoid overflows entirely.
The same applies to processing f16 values with f32 precision.
Installation
Use the following snippet to install SimSIMD and list available hardware acceleration options available on your machine:
pip install simsimd
python -c "import simsimd; print(simsimd.get_capabilities())"

One-to-One Distance
import simsimd
import numpy as np

vec1 = np.random.randn(1536).astype(np.float32)
vec2 = np.random.randn(1536).astype(np.float32)
dist = simsimd.cosine(vec1, vec2)

Supported functions include cosine, inner, sqeuclidean, hamming, and jaccard.
Dot products are supported for both real and complex numbers:
vec1 = np.random.randn(768).astype(np.float64) + 1j * np.random.randn(768).astype(np.float64)
vec2 = np.random.randn(768).astype(np.float64) + 1j * np.random.randn(768).astype(np.float64)

dist = simsimd.dot(vec1.astype(np.complex128), vec2.astype(np.complex128))
dist = simsimd.dot(vec1.astype(np.complex64), vec2.astype(np.complex64))
dist = simsimd.vdot(vec1.astype(np.complex64), vec2.astype(np.complex64)) # conjugate, same as `np.vdot`

Unlike SciPy, SimSIMD allows explicitly stating the precision of the input vectors, which is especially useful for mixed-precision setups.
dist = simsimd.cosine(vec1, vec2, "i8")
dist = simsimd.cosine(vec1, vec2, "f16")
dist = simsimd.cosine(vec1, vec2, "f32")
dist = simsimd.cosine(vec1, vec2, "f64")

It also allows using SimSIMD for half-precision complex numbers, which NumPy does not support.
For that, view data as continuous even-length np.float16 vectors and override type-resolution with complex32 string.
vec1 = np.random.randn(1536).astype(np.float16)
vec2 = np.random.randn(1536).astype(np.float16)
simd.dot(vec1, vec2, "complex32")
simd.vdot(vec1, vec2, "complex32")

One-to-Many Distances
Every distance function can be used not only for one-to-one but also one-to-many and many-to-many distance calculations.
For one-to-many:
vec1 = np.random.randn(1536).astype(np.float32) # rank 1 tensor
batch1 = np.random.randn(1, 1536).astype(np.float32) # rank 2 tensor
batch2 = np.random.randn(100, 1536).astype(np.float32)

dist_rank1 = simsimd.cosine(vec1, batch2)
dist_rank2 = simsimd.cosine(batch1, batch2)

Many-to-Many Distances
All distance functions in SimSIMD can be used to compute many-to-many distances.
For two batches of 100 vectors to compute 100 distances, one would call it like this:
batch1 = np.random.randn(100, 1536).astype(np.float32)
batch2 = np.random.randn(100, 1536).astype(np.float32)
dist = simsimd.cosine(batch1, batch2)

Input matrices must have identical shapes.
This functionality isn't natively present in NumPy or SciPy, and generally requires creating intermediate arrays, which is inefficient and memory-consuming.
Many-to-Many All-Pairs Distances
One can use SimSIMD to compute distances between all possible pairs of rows across two matrices (akin to scipy.spatial.distance.cdist).
The resulting object will have a type DistancesTensor, zero-copy compatible with NumPy and other libraries.
For two arrays of 10 and 1,000 entries, the resulting tensor will have 10,000 cells:
import numpy as np
from simsimd import cdist, DistancesTensor

matrix1 = np.random.randn(1000, 1536).astype(np.float32)
matrix2 = np.random.randn(10, 1536).astype(np.float32)
distances: DistancesTensor = simsimd.cdist(matrix1, matrix2, metric="cosine") # zero-copy
distances_array: np.ndarray = np.array(distances, copy=True) # now managed by NumPy

Multithreading
By default, computations use a single CPU core.
To optimize and utilize all CPU cores on Linux systems, add the threads=0 argument.
Alternatively, specify a custom number of threads:
distances = simsimd.cdist(matrix1, matrix2, metric="cosine", threads=0)

Using Python API with USearch
Want to use it in Python with USearch?
You can wrap the raw C function pointers SimSIMD backends into a CompiledMetric and pass it to USearch, similar to how it handles Numba's JIT-compiled code.
from usearch.index import Index, CompiledMetric, MetricKind, MetricSignature
from simsimd import pointer_to_sqeuclidean, pointer_to_cosine, pointer_to_inner

metric = CompiledMetric(
pointer=pointer_to_cosine("f16"),
kind=MetricKind.Cos,
signature=MetricSignature.ArrayArraySize,
)

index = Index(256, metric=metric)

Using SimSIMD in Rust
To install, add the following to your Cargo.toml:
[dependencies]
simsimd = "..."

Before using the SimSIMD library, ensure you have imported the necessary traits and types into your Rust source file.
The library provides several traits for different distance/similarity kinds - SpatialSimilarity, BinarySimilarity, and ProbabilitySimilarity.
Spatial Similarity: Cosine and Euclidean Distances
use simsimd::SpatialSimilarity;

fn main() {
let vector_a: Vec<f32> = vec![1.0, 2.0, 3.0];
let vector_b: Vec<f32> = vec![4.0, 5.0, 6.0];

// Compute the cosine similarity between vector_a and vector_b
let cosine_similarity = f32::cosine(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Cosine Similarity: {}", cosine_similarity);

// Compute the squared Euclidean distance between vector_a and vector_b
let sq_euclidean_distance = f32::sqeuclidean(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Squared Euclidean Distance: {}", sq_euclidean_distance);
}

Spatial similarity functions are available for f64, f32, f16, and i8 types.
Dot-Products: Inner and Complex Inner Products
use simsimd::SpatialSimilarity;
use simsimd::ComplexProducts;

fn main() {
let vector_a: Vec<f32> = vec![1.0, 2.0, 3.0, 4.0];
let vector_b: Vec<f32> = vec![5.0, 6.0, 7.0, 8.0];

// Compute the inner product between vector_a and vector_b
let inner_product = SpatialSimilarity::dot(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Inner Product: {}", inner_product);

// Compute the complex inner product between complex_vector_a and complex_vector_b
let complex_inner_product = ComplexProducts::dot(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

let complex_conjugate_inner_product = ComplexProducts::vdot(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Complex Inner Product: {:?}", complex_inner_product); // -18, 69
println!("Complex C. Inner Product: {:?}", complex_conjugate_inner_product); // 70, -8
}

Complex inner products are available for f64, f32, and f16 types.
Probability Distributions: Jensen-Shannon and Kullback-Leibler Divergences
use simsimd::SpatialSimilarity;

fn main() {
let vector_a: Vec<f32> = vec![1.0, 2.0, 3.0];
let vector_b: Vec<f32> = vec![4.0, 5.0, 6.0];

let cosine_similarity = f32::jensenshannon(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Cosine Similarity: {}", cosine_similarity);

let sq_euclidean_distance = f32::kullbackleibler(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Squared Euclidean Distance: {}", sq_euclidean_distance);
}

Probability similarity functions are available for f64, f32, and f16 types.
Binary Similarity: Hamming and Jaccard Distances
Similar to spatial distances, one can compute bit-level distance functions between slices of unsigned integers:
use simsimd::BinarySimilarity;

fn main() {
let vector_a = &[0b11110000, 0b00001111, 0b10101010];
let vector_b = &[0b11110000, 0b00001111, 0b01010101];

// Compute the Hamming distance between vector_a and vector_b
let hamming_distance = u8::hamming(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Hamming Distance: {}", hamming_distance);

// Compute the Jaccard distance between vector_a and vector_b
let jaccard_distance = u8::jaccard(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Jaccard Distance: {}", jaccard_distance);
}

Binary similarity functions are available only for u8 types.
Half-Precision Floating-Point Numbers
Rust has no native support for half-precision floating-point numbers, but SimSIMD provides a f16 type.
It has no functionality - it is a transparent wrapper around u16 and can be used with half or any other half-precision library.
use simsimd::SpatialSimilarity;
use simsimd::f16 as SimF16;
use half::f16 as HalfF16;

fn main() {
let vector_a: Vec<HalfF16> = ...
let vector_b: Vec<HalfF16> = ...

let buffer_a: &[SimF16] = unsafe { std::slice::from_raw_parts(a_half.as_ptr() as *const SimF16, a_half.len()) };
let buffer_b: &[SimF16] = unsafe { std::slice::from_raw_parts(b_half.as_ptr() as *const SimF16, b_half.len()) };

// Compute the cosine similarity between vector_a and vector_b
let cosine_similarity = SimF16::cosine(&vector_a, &vector_b)
.expect("Vectors must be of the same length");

println!("Cosine Similarity: {}", cosine_similarity);
}

Half-Precision Brain-Float Numbers
The "brain-float-16" is a popular machine learning format.
It's broadly supported in hardware and is very machine-friendly, but software support is still lagging behind.
Unlike NumPy, you can already use bf16 datatype in SimSIMD.
Luckily, to downcast f32 to bf16 you only have to drop the last 16 bits:
import numpy as np
import simsimd as simd

a = np.random.randn(ndim).astype(np.float32)
b = np.random.randn(ndim).astype(np.float32)

# NumPy doesn't natively support brain-float, so we need a trick!
# Luckily, it's very easy to reduce the representation accuracy
# by simply masking the low 16-bits of our 32-bit single-precision
# numbers. We can also add `0x8000` to round the numbers.
a_f32rounded = ((a.view(np.uint32) + 0x8000) & 0xFFFF0000).view(np.float32)
b_f32rounded = ((b.view(np.uint32) + 0x8000) & 0xFFFF0000).view(np.float32)

# To represent them as brain-floats, we need to drop the second half
a_bf16 = np.right_shift(a_f32rounded.view(np.uint32), 16).astype(np.uint16)
b_bf16 = np.right_shift(b_f32rounded.view(np.uint32), 16).astype(np.uint16)

# Now we can compare the results
expected = np.inner(a_f32rounded, b_f32rounded)
result = simd.inner(a_bf16, b_bf16, "bf16")

Dynamic Dispatch
SimSIMD provides a dynamic dispatch mechanism to select the most advanced micro-kernel for the current CPU.
You can query supported backends and use the SimSIMD::capabilities function to select the best one.
println!("uses neon: {}", capabilities::uses_neon());
println!("uses sve: {}", capabilities::uses_sve());
println!("uses haswell: {}", capabilities::uses_haswell());
println!("uses skylake: {}", capabilities::uses_skylake());
println!("uses ice: {}", capabilities::uses_ice());
println!("uses genoa: {}", capabilities::uses_genoa());
println!("uses sapphire: {}", capabilities::uses_sapphire());

Using SimSIMD in JavaScript
To install, choose one of the following options depending on your environment:

npm install --save simsimd
yarn add simsimd
pnpm add simsimd
bun install simsimd

The package is distributed with prebuilt binaries, but if your platform is not supported, you can build the package from the source via npm run build.
This will automatically happen unless you install the package with the --ignore-scripts flag or use Bun.
After you install it, you will be able to call the SimSIMD functions on various TypedArray variants:
const { sqeuclidean, cosine, inner, hamming, jaccard } = require('simsimd');

const vectorA = new Float32Array([1.0, 2.0, 3.0]);
const vectorB = new Float32Array([4.0, 5.0, 6.0]);

const distance = sqeuclidean(vectorA, vectorB);
console.log('Squared Euclidean Distance:', distance);

Other numeric types and precision levels are supported as well.
For double-precision floating-point numbers, use Float64Array:
const vectorA = new Float64Array([1.0, 2.0, 3.0]);
const vectorB = new Float64Array([4.0, 5.0, 6.0]);
const distance = cosine(vectorA, vectorB);

When doing machine learning and vector search with high-dimensional vectors you may want to quantize them to 8-bit integers.
You may want to project values from the [−1,1] range to the [−127,127] range and then cast them to Int8Array:
const quantizedVectorA = new Int8Array(vectorA.map(v => (v * 127)));
const quantizedVectorB = new Int8Array(vectorB.map(v => (v * 127)));
const distance = cosine(quantizedVectorA, quantizedVectorB);

A more extreme quantization case would be to use binary vectors.
You can map all positive values to 1 and all negative values and zero to 0, packing eight values into a single byte.
After that, Hamming and Jaccard distances can be computed.
const { toBinary, hamming } = require('simsimd');

const binaryVectorA = toBinary(vectorA);
const binaryVectorB = toBinary(vectorB);
const distance = hamming(binaryVectorA, binaryVectorB);

Using SimSIMD in C
For integration within a CMake-based project, add the following segment to your CMakeLists.txt:
FetchContent_Declare(
simsimd
GIT_REPOSITORY https://github.com/ashvardanian/simsimd.git
GIT_SHALLOW TRUE
)
FetchContent_MakeAvailable(simsimd)

After that, you can use the SimSIMD library in your C code in several ways.
Simplest of all, you can include the headers, and the compiler will automatically select the most recent CPU extensions that SimSIMD will use.
#include <simsimd/simsimd.h>

int main() {
simsimd_f32_t vector_a[1536];
simsimd_f32_t vector_b[1536];
simsimd_metric_punned_t distance_function = simsimd_metric_punned(
simsimd_metric_cos_k, // Metric kind, like the angular cosine distance
simsimd_datatype_f32_k, // Data type, like: f16, f32, f64, i8, b8, and complex variants
simsimd_cap_any_k); // Which CPU capabilities are we allowed to use
simsimd_distance_t distance;
distance_function(vector_a, vector_b, 1536, &distance);
return 0;
}

Dynamic Dispatch
To avoid hard-coding the backend, you can rely on c/lib.c to prepackage all possible backends in one binary, and select the most recent CPU features at runtime.
That feature of the C library is called dynamic dispatch and is extensively used in the Python, JavaScript, and Rust bindings.
To test which CPU features are available on the machine at runtime, use the following APIs:
int uses_neon = simsimd_uses_neon();
int uses_sve = simsimd_uses_sve();
int uses_haswell = simsimd_uses_haswell();
int uses_skylake = simsimd_uses_skylake();
int uses_ice = simsimd_uses_ice();
int uses_genoa = simsimd_uses_genoa();
int uses_sapphire = simsimd_uses_sapphire();

simsimd_capability_t capabilities = simsimd_capabilities();

To differentiate between runtime and compile-time dispatch, define the following macro:
#define SIMSIMD_DYNAMIC_DISPATCH 1 // or 0

Spatial Distances: Cosine and Euclidean Distances
#include <simsimd/simsimd.h>

int main() {
simsimd_f64_t f64s[1536];
simsimd_f32_t f32s[1536];
simsimd_f16_t f16s[1536];
simsimd_i8_t i8[1536];
simsimd_distance_t distance;

// Cosine distance between two vectors
simsimd_cos_i8(i8s, i8s, 1536, &distance);
simsimd_cos_f16(f16s, f16s, 1536, &distance);
simsimd_cos_f32(f32s, f32s, 1536, &distance);
simsimd_cos_f64(f64s, f64s, 1536, &distance);

// Euclidean distance between two vectors
simsimd_l2sq_i8(i8s, i8s, 1536, &distance);
simsimd_l2sq_f16(f16s, f16s, 1536, &distance);
simsimd_l2sq_f32(f32s, f32s, 1536, &distance);
simsimd_l2sq_f64(f64s, f64s, 1536, &distance);

return 0;
}

Dot-Products: Inner and Complex Inner Products
#include <simsimd/simsimd.h>

int main() {
simsimd_f64_t f64s[1536];
simsimd_f32_t f32s[1536];
simsimd_f16_t f16s[1536];
simsimd_distance_t distance;

// Inner product between two vectors
simsimd_dot_f16(f16s, f16s, 1536, &distance);
simsimd_dot_f32(f32s, f32s, 1536, &distance);
simsimd_dot_f64(f64s, f64s, 1536, &distance);

// Complex inner product between two vectors
simsimd_dot_f16c(f16s, f16s, 1536, &distance);
simsimd_dot_f32c(f32s, f32s, 1536, &distance);
simsimd_dot_f64c(f64s, f64s, 1536, &distance);

// Complex conjugate inner product between two vectors
simsimd_vdot_f16c(f16s, f16s, 1536, &distance);
simsimd_vdot_f32c(f32s, f32s, 1536, &distance);
simsimd_vdot_f64c(f64s, f64s, 1536, &distance);

return 0;
}

Binary Distances: Hamming and Jaccard Distances
#include <simsimd/simsimd.h>

int main() {
simsimd_b8_t b8s[1536 / 8]; // 8 bits per word
simsimd_distance_t distance;

// Hamming distance between two vectors
simsimd_hamming_b8(b8s, b8s, 1536 / 8, &distance);

// Jaccard distance between two vectors
simsimd_jaccard_b8(b8s, b8s, 1536 / 8, &distance);

return 0;
}

Probability Distributions: Jensen-Shannon and Kullback-Leibler Divergences
#include <simsimd/simsimd.h>

int main() {
simsimd_f64_t f64s[1536];
simsimd_f32_t f32s[1536];
simsimd_f16_t f16s[1536];
simsimd_distance_t distance;

// Jensen-Shannon divergence between two vectors
simsimd_js_f16(f16s, f16s, 1536, &distance);
simsimd_js_f32(f32s, f32s, 1536, &distance);
simsimd_js_f64(f64s, f64s, 1536, &distance);

// Kullback-Leibler divergence between two vectors
simsimd_kl_f16(f16s, f16s, 1536, &distance);
simsimd_kl_f32(f32s, f32s, 1536, &distance);
simsimd_kl_f64(f64s, f64s, 1536, &distance);

return 0;
}

Half-Precision Floating-Point Numbers
If you aim to utilize the _Float16 functionality with SimSIMD, ensure your development environment is compatible with C 11.
For other SimSIMD functionalities, C 99 compatibility will suffice.
To explicitly disable half-precision support, define the following macro before imports:
#define SIMSIMD_NATIVE_F16 0 // or 1
#define SIMSIMD_NATIVE_BF16 0 // or 1
#include <simsimd/simsimd.h>

Target Specific Backends
SimSIMD exposes all kernels for all backends, and you can select the most advanced one for the current CPU without relying on built-in dispatch mechanisms.
All of the function names follow the same pattern: simsimd_{function}_{type}_{backend}.

The backend can be serial, haswell, skylake, ice, sapphire, neon, or sve.
The type can be f64, f32, f16, f64c, f32c, f16c, i8, or b8.
The function can be dot, vdot, cos, l2sq, hamming, jaccard, kl, or js.

To avoid hard-coding the backend, you can use the simsimd_metric_punned_t to pun the function pointer and the simsimd_capabilities function to get the available backends at runtime.
