Performance calculation using FLOPS for LAPACK/LAPACKE APIs.

[mopathan]

Hi All,
Hope you are doing well and safe.

Currently, we are facing difficulty to get the performance calculation (FLOPS count) of each LAPACK/LAPACKE API using FLOP count for verification.
Either we will search in internet for each API and for few APIs, we will get in Intel MKL website. Some we may found and others may not.

Can you please help to add performance info as comment in each LAPACK/LAPACKE API source code?
Also request to add performance info in each API documentation in netlib documentation.
http://www.netlib.org/lapack/explore-html/globals_func_s.html

Example, for SSTEQR() API, we have calculation details in MKL link: https://www.intel.com/content/www/us/en/develop/documentation/onemkl-developer-reference-c/top/lapack-routines/lapack-least-squares-and-eigenvalue-problem/lapack-least-square-eigenvalue-problem-computation/symmetric-eigenvalue-problems-lapack-computation/steqr.html

But in Netlib, we can not find any such information.

Thanks,
Younas.

I think this is a recurring question we get - anybody wants to weigh in?
