Many modern processors come with support for SIMD technology (single instruction, multiple data), which allow for the same mathematical operation to be performed on a set of numbers concurrently on a single core. simdgo library uses x86 assembly SIMD instructions to allow you to leverage SIMD instructions in your Go code.
Execute in the shell of an active Go project:
go get github.com/xtt28/simdgo
You can use golang.org/x/sys/cpu package to check if the CPU supports SSE and
AVX instructions.
| Instruction set extension | Functionality | Check if supported |
|---|---|---|
| SSE | 4 x float32 vectors |
cpu.X86.HasSSE |
| AVX | 8 x float32, 4 x float64 vectors |
cpu.X86.HasAVX |
Benchmarks are coming soon.
- Arithmetic operations on floats (add, subtract, multiply, divide)
- 128- and 256-bit vectors (AVX needed for 256-bit vectors)
