class Node

This class represents a node in the Moab Workload Manager. Moab recognizes a node as a collection of resources with a particular set of associated attributes. This definition is similar to the traditional notion of a node found in a Linux cluster or supercomputer wherein a node is defined as one or more CPUs, associated memory, and possibly other compute resources such as local disk, swap, network adapters, and software licenses. Additionally, this node is described by various attributes such as an architecture type or operating system. Nodes range in size from small uniprocessor PCs to large symmetric multiprocessing (SMP) systems where a single node may consist of hundreds of CPUs and massive amounts of memory.

architecture

private String architecture

This node's processor architecture.

classes

private Set classes

(String collection) The classes that this node can be scheduled for.

See Also:

String

featuresReported

private Set featuresReported

(String collection) The features this node advertises. This can be used to define node sets.

See Also:

String

id

private String id

The unique identifier of this node. Note: this field is not user-assigned and is generated by the database.

index

private Integer index

The index for this node as reported by the resource manager.

ipAddress

private String ipAddress

This node's IPv4 address.

isHypervisor

private Boolean isHypervisor

True if the node is a hypervisor, false otherwise. This is based on the NodeOperatingSystemInformation#hypervisorType#hypervisorType field. If hypervisorType is present, the node is a hypervisor. If it is null, then it is not a hypervisor.

jobs

private Set jobs

(DomainProxy collection) Jobs associated with this node.

See Also:

DomainProxy

lastUpdatedDate

private Date lastUpdatedDate

The timestamp of the last moment when this node was updated. There is no guarantee that all user modifications to a node would be picked up. This will also be changed every RMPOLLINTERVAL even if a resource manager does not report information on this node.

messages

private Set messages

(Message collection) The list of messages attached to this node. They can be attached by admins, the resource manager layer, or triggers. Valid during PUT.

See Also:

metrics

private Map metrics

(Map of String => Double) Metrics are the measurable, quantitative, and changing aspects of this node. They are used to define workload placement, attach triggers, etc. There are some built-in metrics:

• speed - A number from 0.0 to 1.0 describing the relative speed of the system for computational tasks. This is a composite metric, and is defined on a per-site basis.
• cpuLoad - This is the CPU load on this node. This value is defined at the resource manager layer, but is generally defined on a per-operating system basis:
  • Unix-based OS's using some aspect of the Unix load average, as reported by the resource manager layer
  • Windows-based OS's using CPU utilization

Valid during PUT.

See Also:

Double

migrationDisabled
