Hi Choi,
Could you please share some information like the OS etc. and how you expect about 400GFlops?
is it the Peak double floating points GLOPS 1.7G *8 * 256/64 x2(add+muti)x2(FMA) = 217.6GFLP? https://en.wikipedia.org/wiki/FLOPS
We had some explanation about how to use the benchmark in MKL developer guide
and some MKL benchmark https://software.intel.com/en-us/mkl/features/benchmarks about the performance of Xeon.
Best Regards,
Ying

HI Ying,
My OS is CentOS 7.1(64-bit) and CPU is Xeon D-1539.
I expect based on the following.
409.6 GFLOPS = 1.6GHz x 8 cores x 8(single precision data) x 2 FMAs x 2 dispatch ports
Thank you.

Hey Ying,
I know it's an old thread, but I guess here is my best shot. I want to read your guide since I'm investigating Performance Variation and the Intel HPL Linpack seems a fitting benchmark. But The links only says "Access Denied" for me.
Can I somehow get acces or find another guidance how to use it correctly?
Regards,
Lukas
