Platform-independent SIMD in Go
Go 1.26 and 1.27 include experimental APIs for Single Instruction Multiple Data SIMD operations. SIMD is a native feature of many modern CPUs that allows software to perform uniform operations across vectors of data very quickly, such as adding 8 pairs of float64 values in a single instruction. It can significantly speed up many computationally-intensive tasks, ranging from cryptography to data processing to AI. In fact, Go’s Green Tea garbage collector/blog/greenteagc even makes use of SIMD to accelerate scanning memory for live objects.
