Billing types​

Nodes on the platform are categorized by billing type: pay-as-you-go, prepaid (monthly/yearly), and subscription.

  • Pay-as-you-go: Use on demand. Billing starts after creation succeeds and stops after release.

  • Prepaid (monthly/yearly): Purchase multiple months or 1 year upfront.

  • Subscription: License-based model billed as a one-time charge per contract.

  • Billing type conversion:

    • Pay-as-you-go -> Prepaid: In dynamic nodes, only nodes with manual power-on can be converted to prepaid. After conversion, the node type changes from dynamic to static.
    • Prepaid -> Pay-as-you-go: After a prepaid node expires, it can be converted to pay-as-you-go. Node type remains static.
    • Other billing types cannot be converted to each other.

Clusters​

  • Cluster: A cluster is a collection of nodes for high-performance computing. It provides compute capability beyond a single node with benefits such as high performance, elastic scaling, and stability. A cluster includes nodes, a scheduler, and related resources.
  • Cluster nodes: Cluster nodes include head nodes, compute nodes, and login/submit nodes. Each node is a server.
    • Login node: Used for software installation, compilation, debugging, and job submission.
    • Compute node: Used to execute HPC workloads.
    • Head node: Manages scheduler operations and job scheduling.

Node types​

Nodes are categorized by node type: base nodes, static nodes, and dynamic nodes.

  • Base node: Cannot be added to clusters or desktops.
    • A node not created within the Fastone platform.
  • Static node: Not released when a cluster/desktop is released.
    • A node created from the Host Management page.
  • Dynamic node: Released when a cluster/desktop/task is released.
    • Nodes created when creating a cluster.
    • Nodes created when submitting a task.
    • Nodes created when creating a desktop.
  • Node type conversion
    • Dynamic -> Static: When a dynamic node is converted to prepaid, it becomes a static node.
    • Static -> Dynamic: Not supported.
    • Other node types cannot be converted to each other.

Node power-on modes​

Dynamic nodes are categorized by power-on mode: manual nodes and automatic nodes.

  • Manual nodes: Dynamic nodes that require manual release.
    • Nodes created when creating a cluster, including head/login/compute nodes (excluding nodes created by autoscaling).
    • Nodes created when creating a desktop.
  • Automatic nodes: Dynamic nodes automatically released under program control.
    • Nodes created when creating a task.
    • Nodes created by autoscaling.
  • Power-on modes cannot be converted to each other.
