Notational Conventions

The following term is used in reference to the operating system.

macOS*

This term refers to information that is valid on all supported macOS* and OS X* operating systems.

The following notations are used to refer to Intel® oneAPI Math Kernel Library directories.

<parent directory>

The installation directory that includes Intel® oneAPI Math Kernel Library directory; for example, the directory for Intel® Parallel Studio XE Composer Edition.

<mkl directory>

The main directory where Intel® oneAPI Math Kernel Library is installed:

<mkl directory>=<parent directory>/mkl.

Replace this placeholder with the specific pathname in the configuring, linking, and building instructions.

The following font conventions are used in this document.

Italic

Italic is used for emphasis and also indicates document names in body text, for example:
see Intel® oneAPI Math Kernel Library Developer Reference.

Monospace lowercase mixed with uppercase

Indicates:

  • Commands and command-line options, for example,

    icc myprog.c -L$MKLPATH -I$MKLINCLUDE -lmkl -liomp5 -lpthread  

  • Filenames, directory names, and pathnames, for example,

    /System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home

  • C/C++ code fragments, for example,
    a = new double [SIZE*SIZE];

UPPERCASE MONOSPACE

Indicates system variables, for example, $MKLPATH.

Monospace italic

Indicates a parameter in discussions, for example, lda.

When enclosed in angle brackets, indicates a placeholder for an identifier, an expression, a string, a symbol, or a value, for example, <mkl directory>. Substitute one of these items for the placeholder.

[ items ]

Square brackets indicate that the items enclosed in brackets are optional.

{ item | item }

Braces indicate that only one of the items listed between braces should be selected. A vertical bar ( | ) separates the items.
