The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
oneDNN

5 3,456 10.0 C++

oneAPI Deep Neural Network Library (oneDNN)

Project mention: Blaze: A High Performance C++ Math library | news.ycombinator.com | 2024-04-17

If you are talking about non-small matrix multiplication in MKL, is now in opensource as a part of oneDNN. It literally has exactly the same code, as in MKL (you can see this by inspecting constants or doing high-precision benchmarks).
For small matmul there is libxsmm. It may take tremendous efforts make something faster than oneDNN and libxsmm, as jit-based approach of https://github.com/oneapi-src/oneDNN/blob/main/src/gpu/jit/g... is too flexible: if someone finds a better sequence, oneDNN can reuse it without major change of design.
But MKL is not limited to matmul, I understand it...

sse2neon

7 1,220 7.4 C++

A translator from Intel SSE intrinsics to Arm/Aarch64 NEON implementation
remill

3 1,177 6.4 C++

Library for lifting machine code to LLVM bitcode

Project mention: Revng translates (i386, x86-64, MIPS, ARM, AArch64, s390x) binaries to LLVM IR | news.ycombinator.com | 2024-01-12

Usually such things are called lifters. Wonder how this tool compares to other existing LLVM IR lifters, such as remill[0] and rellume[1].
