When building applications that call

Intel® oneAPI Math Kernel Library

functions, it may be useful to determine:

You can get an application to print this information to a standard output device by enabling

Intel® oneAPI Math Kernel Library

Verbose. Functions that can print this information are referred to as

verbose-enabled functions

.

When Verbose mode is activein an

Intel® oneAPI Math Kernel Library

domain, every call of a verbose-enabled function finishes with printing a human-readable line describing the call. However, if your application gets terminated for some reason during the function call, no information for that function will be printed. The first call to a verbose-enabled function also prints a version information line.

To enable the

Intel® oneAPI Math Kernel Library

Verbose mode for an application, do

one of the following:

To disable the

Intel® oneAPI Math Kernel Library

Verbose mode,call the

mkl_verbose

(0) function.Both enabling and disabling of the Verbose mode using the function call takes precedence over the environment setting. For a full description of the

mkl_verbose

function, see either the

Intel® oneAPI Math Kernel Library

Developer Reference for C

or the

Intel® oneAPI Math Kernel Library

Developer Reference for Fortran.

Both references are available in the Intel® Software Documentation Library.

You can enable

Intel® oneAPI Math Kernel Library

Verbose mode in these domains:

BLAS
LAPACK
ScaLAPACK (selected functionality)
FFT

Intel® oneAPI Math Kernel Library

Verbose mode is not a thread-local but a global state. In other words, if an application changes the mode from multiple threads, the result is undefined.
