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.
