LSF Version 7.3 - Administering Platform LSF

Configuring lsf.cluster.cluster_name ResourceMap Section
258 Administering Platform LSF
◆ Each host in the cluster has the resource
◆ The resource is shared by all hosts in the cluster
◆ There are multiple instances of a resource within the cluster, and each instance
is shared by a unique subset of hosts.
Syntax
([resource_value@][host_name... | all [~host_name]... | others | default] ...)
◆ For static resources, you must include the resource value, which indicates the
quantity of the resource. Do not specify the resource value for dynamic
resources because information about dynamic resources is updated by ELIM.
◆ Type square brackets around the list of hosts, as shown. You can omit the
parenthesis if you only specify one set of hosts.
◆ Each set of hosts within square brackets specifies an instance of the resource.
The same host cannot be in more than one instance of a resource. All hosts
within the instance share the quantity of the resource indicated by its value.
◆ The keyword all refers to all the server hosts in the cluster, collectively. Use the
not operator (~) to exclude hosts or host groups.
◆ The keyword others refers to all hosts not otherwise listed in the instance.
◆ The keyword default refers to each host in the cluster, individually.
Non-batch configuration
The following items should be taken into consideration when configuring
resources.
◆ In lsf.cluster.cluster_name, the Host section must precede the
ResourceMap section, since the ResourceMap section uses the host names
defined in the
Host section.
◆ Use the RESOURCES column in the Host section of the
lsf.cluster.cluster_name file to associate static Boolean resources with
particular hosts.
◆ Most resources specified in the ResourceMap section are interpreted by LSF
commands as shared resources, which are displayed using
lsload -s or
lshosts -s. The exceptions are:
❖ Non-shared static resources
❖ Dynamic numeric resources specified using the default keyword. These
are host-based resources and behave like the built-in load indices such as
mem and swp. They are viewed using lsload -l or lsload -I.
