optimized stream benchmark source

I tested some benchmarks(stream, hpl, hpcg) on the server, But, I can't get good performance.

Yesterday, I read HPC tuning guide for AMD EPYC processor Rev.0.7 issued by Dec 2018 and I found this sentence "Please note, there is a heavily optimized version of STREAM from AMD that will provide 300GB/s memory bandwidth. Please contact your AMD representative if you are interested in accessing this code.".

So, Can I get this optimized stream source?

On my epyc server, I got maximum 120 GB/s stream triad bandwidth (with HPC tuning guide for AMD EPYC).

Sincerely, Seungwoo Rho
