Application total floating operation counts with APS(VTune)

[youn__kihang]

Hi All,

I was trying to calculate total number of floating operation counts of my application.

So, I ran an application with aps like below.

mpirun -np 5760 aps ./app.exe
aps --report aps_result_20220214

But, the only things that I found from aps reports are below.

• Elapsed Time: 64104.82
• IPC Rate: 109.12
• SP GFLOPS: 2776.86
• DP GFLOPS: 197.18

I thought about the relationship between GFLOPS and elapsed time, I came up with the following equation.

Total floating counts = Etime*(a*SFlops + b*DFlops)

What should the weights (a and b values) be? I did a web search and it says a=1, b=1, is that correct? Or should the SP/DP weight be different?

Thanks in advance,

Kihang

Hello,

In terms of number of operations regardless of precision you are correct: a=1, b=1.

Thanks & Regards, Dmitry
