Description

The setres command allows an arbitrary block of resources to be reserved for use by jobs which meet the specified access constraints. The timeframe covered by the reservation can be specified on either an absolute or relative basis. Only jobs with credentials listed in the reservation ACL (i.e., USERLIST, GROUPLIST,...) can utilize the reserved resources. However, these jobs still have the freedom to utilize resources outside of the reservation. The reservation will be assigned a name derived from the ACL specified. If no reservation ACL is specified, the reservation is created as a system reservation and no jobs will be allowed access to the resources during the specified timeframe (valuable for system maintenance, etc). See the Reservation Overview for more information.

Reservations can be viewed using the showres command and can be released using the releaseres command.

Example 1

Reserve two nodes for use by users john and mary for a period of 8 hours starting in 24 hours

> setres -u john:mary -s +24:00:00 -d 8:00:00 TASKS==2

reservation 'john.1' created on 2 nodes (2 tasks)

node001:1
node005:1

Example 2

Schedule a system wide reservation to allow a system maintenance on Jun 20, 8:00 AM until Jun 22, 5:00 PM.

> setres -s 8:00:00_06/20 -e 17:00:00_06/22 ALL

reservation 'system.1' created on 8 nodes (8 tasks)

node001:1
node002:1
node003:1
node004:1
node005:1
node006:1
node007:1
node008:1

Example 3

Reserve one processor and 512 MB of memory on nodes node003 through node 006 for members of the group staff and jobs in the interactive class.

> setres -r PROCS=1:MEM=512 -g staff -l interactive 'node00[3-6]'

reservation 'staff.1' created on 4 nodes (4 tasks)

node003:1
node004:1
node005:1
