mkl_verbose_output_file to same output as main code

[JeffS]

My code generates an output file as many do...  There are a number of MKL calls throughout the code and I want to MKL_VERBOSE output to go to the same output file that my code is writing to.

I tried to implement this by using mkl_verbose_output_file(filePath)

• If I set filePath to my output file... the return code is 0 (Success), but there is no verbose output in the file.
• If I set filePath to another file name, return code is 0, and I do get output to the path I set

Can the MKL_VERBOSE output be directed to a file that is shared with the main code?

If everything goes to stdout (program output and MKL_VERBOSE), then I can capture by piping to a file.  However this code is run using MPI master/slave so I cannot just dump to stdout.

Side note:  mkl_verbose_output_file seems to require calling with trim(filePath).  I was getting a return status of 1 until I used trim().  I would expect it to work like open() where it handles trimming inherently.

Hi,

Thanks for posting in Intel Communities.

>>If I set filePath to another file name, return code is 0, and I do get output to the path I set

Could you please kindly clarify if the mentioned output refers to verbose information, the actual code output, or a combination of both?

Thanks and Regards,

Aryan.

The output is only the MKL_VERBOSE output.

I want to achieve combined output to a single file.  Without using std out.

Hi,

Thanks for sharing your requirement. 

This feature is currently not available. We will update this thread once we implement this feature. 

Thanks & Regards,

mkl_verbose_output_file doesn't require to call trim() now. This feature has been added in 2025.0 release.
