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?
Just run them and see how long the program tells you til it solves. The estimated time is pretty close to being accurate. No way to know since I don't know the speed and grid size of the A100s.
