Allocate shared cluster resources

Analyze packing, fairness, topology, gang scheduling, preemption, and fragmentation for heterogeneous shared compute clusters.

  1. 01

    Resource requests and feasibility

    Separate admission accounting, runtime consumption, and enforcement while checking every required resource dimension.

    25 min
  2. 02

    Multidimensional resource packing

    Use lower bounds, explicit assignments, and heuristic limits instead of equating a good score with an optimal placement.

    25 min
  3. 03

    Dominant resource fairness

    Normalize heterogeneous resource demands, compare dominant shares, and state the assumptions behind a fairness policy.

    25 min
  4. 04

    Topology and affinity constraints

    Treat device locality, communication, and failure-domain requirements as explicit constraints with measurable tradeoffs.

    25 min
  5. 05

    Gang scheduling and co-scheduling

    Coordinate multi-worker admission while distinguishing resource readiness from synchronized execution and eventual job progress.

    25 min
  6. 06

    Preemption and victim selection

    Release the right feasible resources while accounting for disruption, checkpointing, lost progress, and policy boundaries.

    25 min
  7. 07

    Accelerator resource fragmentation

    Separate device count, per-device memory, partition profiles, and useful compute before attempting consolidation.

    25 min
  8. 08

    Queue fairness and aging

    Define waiting, entitlement, and job progress explicitly while evaluating starvation and large-job admission.

    25 min
  9. 09

    Reservations and capacity borrowing

    Define entitlements, unused quota, revocation, and physical placement instead of treating borrowed resources as permanent capacity.

    25 min
  10. 10

    Scheduler simulation and trace replay

    Calibrate workload and cost models, compare policies consistently, and preserve the limits of counterfactual conclusions.
