NAME¶

oar_resource_init - Helper script to define OAR resources by SSHing to nodes

SYNOPSIS¶

oar_resource_init <hosts_file> [options]

DESCRIPTION¶

The script takes a list of hosts from the file given as parameter and generates the OAR commands to add the resources which define those hosts in the OAR database. Generated commands are written by default in /tmp/oar_resources_init.cmd host_file must contain one host per line and the hosts must have their "oar-node" service started (this script connects to the hosts via ssh on the port 6667). The default resource hierarchy which is filled by this script is: host --> cpu --> core.

OPTIONS¶

-o [file]

Pathname for the output file to store the generated commands

-H

This option can be used when Intel HyperThreading is enabled on the nodes. So for each declared core in the OAR database, the 2 corresponding threads are assigned.

-T

This option can be used when Intel HyperThreading is enabled on the nodes. It adds the property "thread" in the OAR database and fills it with the hierarchy: host --> cpu --> core --> thread.
