I am using IPP lib 2019 version1.

Implemented one feature in C++ tested in two set of machines.

1) Intel Xeon Platinum 8160 processor took 1.5 secs to complete the flow.

2) Intel Xeon CPU E5-2699 v4 processor took 70 secs to complete the flow.

Is there any dependencies to use IPP library. If yes, Could you please anyone let me know.

Hi Mopu.

Could you please provide more information about your flow?

  • IPP functions list
  • Output of ippGetLibVersion

May be some reproducer?

At least AVX512 instruction set is available in Intel Xeon Platinum 8160.

Thanks.

Hi Mopu.

There is small benchmark in attachment with ippiAdd_32f_C1R function.

Could you please compile it and provide it's output at 2 your systems? And may be redesign it according with your workload.

Thanks,

Andrey.

Hi Andrey,

I have tried to compile that piece of code. It's not working. 

Then I have searched in Google. They were telling if we use namespace 'Ipp" lib it will restrict for single thread processing. if we use namespace "IppST" it will handle multithread processing.

Now, Faster machine didn't change the TPT improvement. But Slower machine improved a bit higher TPT and reduces (70 secs to 10 secs).
