SIMD for C++ Developers 学习笔记我的动机和准备工作我打算给llama.cpp做个s390x的支持. 目前人工智能领域用到的包, 需要SIMD向量化的库太多了, 这项技能也越来越有用了, 安利这项技术给大家. 准备工作先用gpt翻…
We recommend these resources for getting started: SIMD for C++ Developers Algorithms for Modern Hardware Optimizing software in C++ Improving performance with SIMD intrinsics in three use cases Examples Online demos using Compiler Explorer: multiple targets with dynamic dispatch(more complicated, but flexib...
Arm SIMD Best Practices: Optimize your code for mobile, laptops, IoT, and embedded devices. Boost performance for cloud and edge development.
Neon intrinsics是一组编译器用来替代Neon 指令的的内建函数，该内建函数风格跟C/C++函数一致，方便普通...
But for developers who need to squeeze every bit of performance out of their applications, that's not enough. Since the dawn of computing, performance-minded programmers have used insights about hardware to fine tune their code. Let's say you're working on code for which speed is paramount,...
(Boolean extremum solution algorithm of NumPy) is used to describe the process of optimizing the algorithm using NEON and some key techniques. Compared with the C code optimization using a compiler, the performance is improved by about 80%. The following content is very helpful for developers ...
Libraries written in C/C++ enable developers to write SIMD-hardware-oblivious application code and create code for specific SIMD extensions with little overhead. The separation into SIMD-hardware-oblivious code and a SIMD abstraction library reduces complexity and makes it ...
“The RISC-V P extension within the Andes cores addresses the key real-time requirements in SIMD/DSP computations for new markets in audio/speech, IoT, tinyML and edge devices. Together with the Andes certified Imperas reference models, SoC developers can explore the next generation d...

Alternatively, developers may choose to target a single instruction set without any runtime overhead. In both cases, the application code is the same except for swapping HWY_STATIC_DISPATCH with HWY_DYNAMIC_DISPATCH plus one line of code. See also @kfjahnke's introduction to dispatching. ...
