Call Description Line
In
Verbose mode, each verbose-enabled function called from your application prints a call description line. The line begins with the
Intel® oneAPI Math Kernel Library
MKL_VERBOSE
character string and uses spaces as delimiters. The format of the rest of the line may change in a future release.
The following table lists information contained in a call description line and provides available links for more information:

---|---|---|
The name of the function.
| Although the name printed may differ from the name used in the source code of the application (for example, the
cblas_ prefix of CBLAS functions is not printed), you can easily recognize the function by the printed name.

Values of the arguments.

Time taken by the function.
|
| Managing Multi-core Performance for options to set an affinity mask.
|
Value of the
MKL_CBWR environment variable.

The following is an example of a call description line:

The following information is not printed because of limitations of
Verbose mode:
Intel® oneAPI Math Kernel Library
- Input values of parameters passed by reference if the values were changed by the function.For example, if a LAPACK function is called with a workspace query, that is, the value of thelworkparameter equals -1 on input, the call description line prints the result of the query and not -1.
- Return values of functions.For example, the value returned by the functionilaenvis not printed.
- Floating-point scalars passed by reference.
