Beating NumPy’s Matrix Multiplication in 150 lines of C code

In this step by step tutorial we’ll optimize matrix multiplication on CPU in C achieving over 1 TFLOPS on an 8-core Ryzen 7 7700. The final optimized implementation is just 150 LOC and outperforms both OpenBLAS and MKL on Ryzen 7 7700. High-performance GEMM…

Meta 推出 LLM Compiler 代码优化模型，可搭配其他 AI 改善代码生成 / 编译能力

Meta 前天推出了一款名为“LLM Compiler”的模型，该模型基于 Meta 现有的 Code Llama 打造，主打代码优化，目前相关模型已登陆 Hugging Face，提供 70 亿参数及 130 亿参数两个版本，允许学术及商业使用。

Meta 认为，尽管业界各大语言模型已在各种编程代码任务中展现了出色的能力，但此类模型在代码优化还有进步空间，目前推出的 LLM Compiler 模型便是一款专为优化代码任务设计的预训练模型，能够模拟编译器对代码进行优化，或将“已经过优化的代码转换回原本的语言”。

LLM Compiler 在 5460 亿个 LLVM-IR 和汇编代码标记的庞大语料库上进行了训练，据称能够达到 77% 的“代码优化潜力”，开发者可以自由将相关模型配合其他 AI 模型一起使用，从而改善生成代码的质量。

How much memory does a call to ‘malloc’ allocates?

In C, we allocate memory on the heap using the malloc function. Other programming languages like C++ or zig often call on malloc underneath so it is important to understand how malloc works. In theory, you could allocate just one byte like so: char * buffer…

GCC's new fortification level: The gains and costs | Red Hat Developer

This article describes a new level of fortification supported in GCC. This new level detects more buffer overflows and bugs which mitigates security issues in applications at run time.

Your Own Constant Folder in C/C++

I was talking with someone today that really really wanted the sqrtps to be used in some code they were writing. And because of a quirk with clang (still there as of clang 18.1.0), if you happened to use -ffast-math clang would butcher the use of the intrinsic.…
