I learned about the new range API of std::optional from Steve Downey at CppCon 2025 during his talk about std::optional. To be honest, I found the idea quite strange at first. I wanted to dig deeper to understand the motivation and the implications. The first example I encountered was this: 1 2 3 4 5 6 7 void doSomething(std::string const& data, std::optional logger = {}) { for (auto l : logger) { l.log(data); } return; } This shows that you can iterate over an optional. In fact, iterating ov...| Sandor Dargo’s Blog

In this blog post, we walk through how to use Matrix Cores in HIP kernels, with a focus on low-precision data types such as FP16, FP8, and FP4, as well as the new family of Matrix Core instructions with exponent block scaling introduced in the AMD CDNA™4 architecture. Through code examples and illustrations, we provide the necessary knowledge to start programming Matrix Cores, covering modern low-precision floating-point types, the Matrix Core compiler intrinsics, and the data layouts requi...| AMD ROCm Blogs

If you’re a regular reader of my blog, you know I’ve been sharing what I learn about new C++ language and library features ever since C++20. You probably also read my CppCon 2025 Trip Report. And this post is where the two come together. At CppCon I attended a great talk by Steve Downey about std::optional.

[RFC] Ripple: A Compiler-Interpreted API for Efficient SIMD Programming TL;DR We have been working on Ripple, a lean addition to LLVM to support Single-Program, Multiple-Data (SPMD) and loop-annotation-based parallel programming for SIMD hardware.
