# Introduction

> Expanse is the intelligence layer for HPC compute. Resource predictions, failure diagnostics, and waste visibility for the workloads your compute estate runs.

## What is Expanse?

Expanse helps platform teams run HPC compute with more capacity and fewer failed jobs. It captures every workload on your computes (SLURM, Kubernetes, Nomad) without asking users to change how they submit, predicts resource needs before submission, and surfaces solution-oriented guidance after failures.
