intel-mkl-src

Source crate for Intel-MKL

intel-mkl-sys

FFI for Intel-MKL vector math, and statistical functions

intel-mkl-tool

CLI utility for redistributing Intel-MKL

Redistribution of Intel MKL as a crate. Tested on Linux, macOS, and Windows (since 0.4.0)

Supported features

• mkl-*-*-* features specify which MKL to be linked

  • static means MKL will be linked statically, and dynamic means MKL will be linked dynamically

  • lp64 means 32-bit integer interface, ilp64 means 64-bit integer interface

  • iomp means MKL uses Intel OpenMP, seq means sequential execution, e.g. no parallelization

    • OpenMP is not supported for Windows currently #46

  • default is mkl-static-ilp64-seq, and you must choose one of them.

  • macOS is not supported #42

• download feature enables downloading MKL archive managed by this project from AWS S3 (default ON)

Usage

This crate is a *-src crate. This downloads and link Intel MKL, but does not introduce any symbols. Please use blas-sys, lapack-sys, or fftw-sys to use BLAS, LAPACK, FFTW interface of MKL, e.g.

[dependencies]
fftw-sys = { version = "0.4", features = ["intel-mkl"] }

How to find system MKL libraries

This crate seeks system MKL libraries, e.g. installed by apt, yum, or official manual installer, as following manner:

• Check ${OUT_DIR} where previous build has downloaded
• Seek using pkg-config crate

  • ${PKG_CONFIG_PATH} has to be set correctly. It may not be set by default in usual install.

  • You can confirm it by checking the following command returns error.

    pkg-config --libs mkl-dynamic-lp64-iomp
    

• (experimental) Seek ${XDG_DATA_HOME}/intel-mkl-tool
• Seek a directory set by ${MKLROOT} environment variable
• Seek default installation path
  • /opt/intel/mkl for Linux
  • C:/Program Files (x86)/IntelSWTools/compilers_and_libraries/windows for Windows

If not found any MKL library and download feature is ON, this crate will download archive from AWS S3 rust-intel-mkl bucket.
