Maui Cluster Scheduler

Paid APILinuxSelf-hosted

Choose Maui when you need policy-based scheduling for a Linux cluster and already have a supported resource manager to manage queues and compute nodes. Its scheduling controls and fairshare rules are the main reasons to consider it. Look elsewhere if you need Maui itself to manage cluster resources or require fuller encryption and GSI-like security as documented capabilities.

    • Sets job eligibility, priority, and placement policies.
    • Supports reservations, QOS levels, backfill, and allocation management.
    • Fairshare accounts for historical resource use across several account types.
    • Works with OpenPBS, PBSPro, Loadleveler, and SGE resource managers.
    • Includes job inspection, cancellation, queue, and usage commands.

    What to know first

    • Requires a separate, installed and operational resource manager.
    • The documented security model uses a shared secret key; fuller encryption was being enhanced.
