l_onemklbench_p_2024.0.0_49515's readme not have EMR and newer CPU(SRF-SP/GNR-SP)'s NB parameter

whytehuang — Tue, 30 Jan 2024 06:45:15 GMT

Hi Intel

Base on IPS:860420(Where can I know HPL.dat NB parameter by SPR and EMR and newer CPU)

Get SPR NB parameter is 1536.

(l_onemklbench_p_2024.0.0_49515 \benchmarks_2024.0\linux\share\mkl\benchmarks\mp_linpack\readme.txt)

But readme not have EMR and newer CPU(SRF-SP/GNR-SP) NB parameter , IPS say need ask at there.

Can you help to check this question? thanks.

the NB parameter is still the same (384) for SPR and EMR CPU

Hi Gennady

May I know why readme show SPR is 1536 ? snd you say is 384?

Thanks!

1536 blocking size value is related to HPL-AI* Benchmark, while 384 - for traditional HPC ( CPU ) base cases.

Please see the snapshoot below from readme.txt:

Recommended blocking sizes (NB in HPL.dat) are listed below for various Intel(R)
architectures:

Intel(R) Xeon(R) Processor X56*/E56*/E7-*/E7*/X7* : 256
Intel(R) Xeon(R) Processor E26*/E26* v2 : 256
Intel(R) Xeon(R) Processor E26* v3/E26* v4 : 192
Intel(R) Xeon(R) Scalable Processors : 384
Intel(R) Xe(R) Graphics Card : 384

Hi Gennady

Thanks for ypur help, so base on "NB parameter is still the same (384) for SPR and EMR CPU"

Does the new CPU: SRF/ GNR CPU also 384? thanks!

Hi Huang,

it is very probably but we couldn't exactly say until the official release of these CPU.

Hi Gennady

Thanks, I will use 384 at BHS system, thanks.
