AMD Optimizing CPU Libraries (AOCL)

NEW! AOCL 5.1 is now available, May 7, 2025

AOCL is a set of numerical libraries optimized for AMD processors based on the AMD “Zen” core architecture and generations. Supported processor families are AMD EPYC™, AMD Ryzen™, and AMD Ryzen™ Threadripper™ processors. The tuned implementations of industry-standard math libraries enable rapid development of scientific and high-performance computing applications.

• AOCL-Compression
• AOCL-Cryptography
• AOCL-FFTW (Fastest Fourier Transform in the West)
• AOCL-LibM (AMD Math Library)

What’s new in AOCL 5.1 (May 7, 2025)

• AOCL Build-It-Yourself (Beta)
  • AOCL now offers the capability to compile individual libraries and consolidate them into a unified binary. With the Build-It-Yourself feature, you can choose one or more AOCL libraries and merge them into a single library by configuring the appropriate CMake options.
  • This unified binary is assigned a default name: libaocl.so/ libaocl.a for Linux and aocl.dll/ aocl.lib for Windows
  • This approach simplifies integration by eliminating dependencies on library linking order and preventing API duplication, ensuring smooth and efficient incorporation of multiple AOCL libraries.
• AOCL-Data Analytics 
  • New APIs for DBSCAN clustering, support vector machines (SVM) and pairwise distances.
  • Dynamic dispatch: multiple Zen generation code paths compiled in a single binary, with appropriate code path selected at runtime.
  • Performance improvements to decision trees, random forest and k-nearest neighbors algorithms.
• AOCL-BLAS
  • Performance Optimizations
    • DGEMM, DTRSM, DGEMV, ZGEMM, DTRSV, DCOPYV on Zen4/5
    • DSCALV, DDOTV on Zen3
  • Benchmark support for ASUMV
  • Aocl-gemm Add-on Module updates
    • AOCL_ENABLE_INSTRUCTIONS support
    • batch_gemm support for all data types
    • New Output Datatype for Integer APIs
    • BF16 Support on AVX2 Platforms
    • WOQ with/without Group Quantization
    • Threading Framework Optimizations
    • Reference Kernels for all Reorder APIs
    • Performance Optimizations for all APIs
    • Additional APIs and Post-Ops support in addition to the improved performance for the existing APIs in aocl_gemm add-on.
• AOCL-Compression
  • Introduced multithreaded APIs for GZIP and Raw Deflate formats.
  • Improved single threaded compression performance for Bzip2, Snappy and decompression performance for Bzip2, Snappy, Gzip, ZSTD.
  • AOCL_DECOMPRESS_FAST support extended to Snappy.
  • Integrated third party utilities: minigzip and zstd utility for benchmarking.
• AOCL-Cryptography
  • Performance improvements in SHA3.
  • AES-GCM optimizations for real world applications.
  • OpenSSL provider support for SHA3 and SHAKE algorithms.
  • Runtime forcing of CPUID / micro arch code path support using aocl-utils

  • • LU Factorizations (DGETRF & DGBTRF), Least Square Solver (ZGELS)
    • SVD (DGESDD) and Eigen Decomposition (DSYEVD)
  • Upgrade to Netlib LAPACK 3.12.0 specifications
  • Updates to CMAKE presets, pkg-config for ease of build and integration
  • Test cases added for C++ template interfaces
• AOCL-LibM
  • Added new vector variants of sincos.
  • Improved performance of vector variants of linearfrac.
  • Added CMAKE support (experimental) for building AOCL-LibM binaries on Linux and Windows.
  • Added static dispatch functionality while building with CMAKE.
