> 本文内容来自《Whole-Function Vectorization》的 Introduction 章节的 SIMD 指令集与数据并行程序小节,为作者的主要工作做知识铺垫,本文不涉及作者的主要工作,仅做 SIMD 概念的基本理解与学习。本文目录:
1. Amdahl's Law 和 Intel MMX
2. SIMD、数据并行、向量处理器的关系
2.1 向量处理器的优缺点和…

The proposal seems to be geared towards a seamless interraction between intrinsics and std::simd, so that you can fall back to intrinsics when the standard does not provide the tools you want.
This…

### Goals
1. Gain an understanding of SIMD operations and use cases
2. Port ML.NET C++ SIMD algorithms to C#
3. Increase ML.NET performance by using AVX operations when supported and where benefici…

### What is the problem this feature will solve?
As I am looking into ways to improve astropy performance, I can see that using the new'ish compiler feature of function multi-versioning should improv…

There are a few places in the code-base where `FEATURE_HW_INTRINSICS` functionality is dependent on `FEATURE_SIMD` also being defined.
The hardware intrinsics feature should (ideally) share code wi…

I am super impressed with this Lua adaptation of dynasm!
I have hooked it into Snabb Switch over here: SnabbCo/snabbswitch#575 and look forward to getting some experience. (The integration is a bit m…

## Background
After doing a little bit of research on previous issues mentioning adding SIMD to Go, I found the following proposals:
#58610: This proposal relies on the `ispmd` keyword which doe…
