%description

LIBXSMM is a library for small dense and small sparse matrix-matrix

multiplications, as well as for deep learning primitives such as small

convolutions targeting Intel Architecture (x86).  The library

generates code for the following instruction set extensions: Intel

SSE, Intel AVX, Intel AVX2, IMCI (KNCni) for Intel Xeon Phi

coprocessors ("KNC"), and Intel AVX‑512 as found in the Intel Xeon Phi

processor family ("KNL") and future Intel Xeon processors.  Small

convolutions are currently only optimized for Intel AVX‑512.

Historically the library was solely targeting the Intel Many

Integrated Core Architecture "MIC") using intrinsic functions.

Currently, optimized assembly code targets all aforementioned

instruction set extensions (static code generation), and Just‑In‑Time

(JIT) code generation targets Intel AVX and beyond.
