Expanse predicts the GPU, memory, runtime, and failure risk of compute jobs before they run, so clusters do more work on the same hardware and reduce failed or overprovisioned jobs. It works alongside existing schedulers such as SLURM, Kubernetes, or Nomad, serving engineers running training, HPC simulations, and inference workloads.
