Center node: "the blas api of blasfeo optimizing performance for small matrices"
  Abstract: BLASFEO is a dense linear algebra library providing high-performance implementations of BLAS- and LAPACK-like routines for use in embedded optimization, and is therefore targeting relatively small matrices. One of the key features of BLASFEO is the use of a packed matrix format as the native format in its API. For matrices fitting in cache, this matrix format is analogous to the packed sub-matrices in the memory buffers of optimized BLAS libraries, but with the key advantage of removing the packing cost from the routine call. Thanks to that, for small matrices BLASFEO outperforms optimized BLAS implementations, both open source and proprietary, on a wide range of computer architectures. This paper investigates the addition of a standard BLAS API to the BLASFEO framework, and proposes an implementation switching between two algorithms, which are optimized for different matrix sizes. By leveraging the modular nature of the assembly kernels framework in BLASFEO, tailored linear algebra kernels with mixed column- and panel-major arguments are easily developed. This BLAS API has generally lower performance than the BLASFEO API, but it nonetheless outperforms optimized BLAS and especially LAPACK libraries for matrices fitting in cache. Therefore, it can be used to boost a wide range of applications, where standard BLAS and LAPACK libraries are employed and the matrix size is moderate. In particular, this paper investigates the benefits in scientific programming languages such as Octave, Python SciPy and Julia.
