Our Commentary ​

Thirty-three points more utilization just by changing the order? That's wild. We're always looking for ways to squeeze more performance out of our hardware, especially with the cost of GPUs these days. This isn't some magic new algorithm; it's just smart resource management. It makes you wonder how much untapped potential is sitting in existing clusters, waiting for someone to rethink the obvious. I'm definitely going to be looking into our own job scheduling after reading this.
