Zielar has/has access to 300+ of the V100s; and he is the one who solved 110 and 115, so that is just kind of the benchmark used to compare how long to solve 120.
Man I wonder where he gets all those V100s from.
It is better to ask
Zielar directly. For sure he had access to 300+ GPUs. But we are not sure he owned them by himself, it was also possible he used the "company's assets".
Why is this important for you?
