Debugging, optimizing, and ensuring sufficient power supply for these massive clusters can take additional time. The actual time to reach full operational capacity may be longer than the initial deployment timeframe.

The Colossus supercomputer uses at least 150 MW of power, as 100,000 H100 GPUs use 70 Megawatts. They have been using 14 diesel generators to power ithe Memphis supercomputer. The power will need to be increased to feed all 100,000 H100 GPUs.
