Performance test with Optimized LINPACK Benchmark

Hi, I evaluated my embedded board, which has Xeon D 1.7GHz(8-cores, 12MB cache and 32GB DDR). The tool is Intel Optimized LINPACK Benchmark in MKL 2018. I expected about 400 GFLOPS but the result was about 145 GFLOPS. I would like to know the result is reasonable or not, and then how to get maximum performance. Thank you.

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

https://software.intel.com/en-us/mkl-linux-developer-guide-intel-optimized-linpack-benchmark-for-lin...

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.

Get it. The benchmark return double precision data by default

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
