Configuring Slot Allocation per Queue
Configuring Slot Allocation per Queue
SLOT_SHARE parameter
SLOT_POOL parameter
Host job slot limit
Steps
Configure as many pools as you need in lsb.queues.
The SLOT_SHARE parameter represents the percentage of running jobs (job
slots) in use from the queue. SLOT_SHARE must be greater than zero (0) and
less than or equal to 100.
The sum of SLOT_SHARE for all queues in the pool does not need to be 100%.
It can be more or less, depending on your needs.
The SLOT_POOL parameter is the name of the pool of job slots the queue
belongs to. A queue can only belong to one pool. All queues in the pool must
share the same set of hosts.
The hosts used by the pool must have a maximum job slot limit, configured
either in lsb.hosts (MXJ) or lsb.resources (HOSTS and SLOTS).
1 For each queue that uses queue-based fairshare, define the following in
lsb.queues:
❖ SLOT_SHARE
❖ SLOT_POOL
2 Optionally, define the following in lsb.queues for each queue that uses
queue-based fairshare:
❖ HOSTS to list the hosts that can receive jobs from the queue
If no hosts are defined for the queue, the default is all hosts.
Hosts for queue-based fairshare cannot be in a host partition.
Examples
❖ PRIORITY to indicate the priority of the queue.
3 For each host used by the pool, define a maximum job slot limit, either in
lsb.hosts (MXJ) or lsb.resources (HOSTS and SLOTS).
◆
The following configures a pool named poolA, with three queues with
different shares, using the hosts in host group groupA:
Begin Queue
QUEUE_NAME = queue1
PRIORITY = 50
SLOT_POOL = poolA
SLOT_SHARE = 50
HOSTS = groupA
...
End Queue
