About:
BLIS is a portable software framework for high-performance BLAS-like linear algebra libraries. It enables the instantiation of optimized routines for various CPU architectures through a configurable build system. Its primary value is delivering near-peak floating-point performance for matrix operations without hardware-specific lock-in.

Key Features:

Configurable build system for targeting specific CPU microarchitectures
Supports both single-threaded and multi-threaded execution via BLAS-compatible APIs
High-performance GEMM (General Matrix Multiply) kernel optimization
Separable framework for developing custom BLAS-like routines

Use Cases:

Accelerating scientific computing and numerical simulations
Serving as a high-performance backend for numerical libraries like NumPy and SciPy
Benchmarking and comparing CPU floating-point performance across architectures

Alternatives:

OpenBLAS – OpenBLAS is a more monolithic fork of GotoBLAS, while BLIS offers a modular framework for customization.
Intel MKL – MKL is a proprietary, highly optimized library for Intel CPUs, whereas BLIS is open-source and portable across vendors.
