Flux is a resource manager for high-performance computing that schedules jobs across HPC clusters, cloud resources, and containers. Unlike traditional resource managers, Flux doesn't require administrator privileges—launch it within other resource managers or Flux itself, on your laptop, or deploy it as your site's primary scheduler.
This means you get a full-featured resource manager for complex workflows, ensemble runs, or testing without waiting for sysadmin support. Schedule 10,000-node MPI jobs, run millions of tasks, or dynamically manage resources within a single batch job.

Command and API references: :ref:`core:man-pages` (job commands) | :ref:`sched:man-pages` (scheduling) | :ref:`security:man-pages` (security tools)
Start with flux-core (:doc:`install guide <core:guide/build>`) for job execution, commands, APIs, and built-in schedulers.
For advanced scheduling, add flux-sched (:doc:`install guide <sched:guide/build>`) to enable the fluxion scheduler with graph-based resource matching.
For multi-user installations, flux-security is required for authentication. flux-accounting provides resource accounting and priority management.
