GitHub - google/highway: Performance-portable, length-agnostic SIMD with runtime dispatch
CPUs provide SIMD/vector instructions that apply the same operation to multiple data items. This can reduce energy usage e.g. fivefold because fewer instructions are executed. We also often see 5-10x speedups. Highway makes SIMD/vector programming practical and workable according to these guiding principles: Does what you expect: Highway is a C++ library with carefully-chosen functions that map we
Changing std::sort at Google’s Scale and Beyond
TL;DR; We are changing std::sort in LLVM’s libcxx. That’s a long story of what it took us to get there and all possible consequences, bugs you might encounter with examples from open source. We provide some benchmarks, perspective, why we did this in the first place and what it cost us with exciting ideas from Hyrum’s Law to reinforcement learning. All changes went into open source and thus I can
GitHub - randombit/botan: Cryptography Toolkit
Botan (Japanese for peony flower) is a C++ cryptography library released under the permissive Simplified BSD license. Botan's goal is to be the best option for cryptography in C++ by offering the tools necessary to implement a range of practical systems, such as TLS protocol, X.509 certificates, modern AEAD ciphers, PKCS#11 and TPM hardware support, password hashing, and post quantum crypto scheme
CBMC: Bounded Model Checking for Software
About CBMC CBMC is a Bounded Model Checker for C and C++ programs. It supports C89, C99, most of C11/C17 and most compiler extensions provided by gcc, clang, and Visual Studio. A variant of CBMC that analyses Java bytecode is available as JBMC. CBMC verifies memory safety (which includes array bounds checks and checks for the safe use of pointers), checks for exceptions, checks for various va
GitHub - milvus-io/milvus: A cloud-native vector database, storage for next generation AI applications
Milvus is an open-source vector database built to power embedding similarity search and AI applications. Milvus makes unstructured data search more accessible, and provides a consistent user experience regardless of the deployment environment. Milvus 2.0 is a cloud-native vector database with storage and computation separated by design. All components in this refactored version of Milvus are state
Cheerp: the C++ compiler for the Web platform.
14 March 2023: Cheerp 3.0 released and relicensed to Apache 2.0 licence! Release notes here. What is Cheerp? Cheerp is an enterprise-grade C/C++ compiler for the web that can compile C/C++ into WebAssembly and JavaScript. It is open source, liberally licensed (LLVM licence) and is actively developed by Leaning Technologies.
SYCL - C++ Single-source Heterogeneous Programming for Acceleration Offload
SYCL (pronounced ‘sickle’) is a royalty-free, cross-platform abstraction layer that: Enables code for heterogeneous and offload processors to be written using modern ISO C++ (at least C++ 17). Provides APIs and abstractions to find devices (e.g. CPUs, GPUs, FPGAs) on which code can be executed, and to manage data resources and code execution on those devices. SYCL defines abstractions to enable he
