Scaling of MKL FFT with number of cores

For 2D, double complex FFT, how does performance scale with number of cores, e.g., dual-core i5 versus quad-core i5?

Ditto for i7.

And how does that compare with 18-core Xeon?

Hello harvey6625249

 

 

Thank you for joining the Intel® community.

 

 

I see that you are looking for the performance difference while running the 2D double complex FFT with a different number of cores. In this case, if you are referring to Intel® Math Kernel Library 2018 – C I would recommend referring to https://software.intel.com/en-us/mkl-developer-reference-c-getting-help-and-support https://software.intel.com/en-us/mkl-developer-reference-c-getting-help-and-support for better assistance on the case.

 

 

You could also refer to https://software.intel.com/en-us/support https://software.intel.com/en-us/support to create an account Intel® developer zone.

 

 

Hope his help.

 

 

Regards,
