I am not too sure how to calculate this, if someone can help me.

We have at the Uni one NVIDIA DGX A100

It packs 5 petaFLOPS, eight A100 GPUs with 320GB of GPU memory.

Realistically, if we get permission to run it 24/7 (which I doubt lol) for the 120 key, how long would it take? Is it feasible? And more important, would the Kangaroo even work on it?

I remember WanderingPhilosipher saying that 256 V100's that were running simultaneously for several years only exhausted 15% of #120, and regardless of how faster an A100 is versus a V100, 8 of them definitely won't make the cut.

And you also have to worry about making Kangaroo dump the private key to a file (if it even supports that without stdout redirects), or you'll lose the key if your terminal session is disconnected.
Negative, that was for #64, using Bitcrack...not #120 using Kangaroo.  And it's the #64 pool that has been set up for a few years and I know that the 256 V100s have ran for weeks at a time along with other cards. Last I checked it was around 15% of total keys checked for #64.

I do not know if Zielar is running his V100s at #120.
