Configure slot allocation per queue

Procedure

For each queue that uses queue-based fairshare, define the following in lsb.queues:
1. SLOT_SHARE
2. SLOT_POOL
Optional: Define the following in lsb.queues for each queue that uses queue-based fairshare:
1. 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.
  
  Tip:
  Hosts for queue-based fairshare cannot be in a host partition.
2. PRIORITY to indicate the priority of the queue.
Optional: Define the following in lsb.queues for the first queue in each slot pool:
1. MAX_SLOTS_IN_POOL to set the maximum number of slots available for use in the slot pool.
2. USE_PRIORITY_IN_POOL to allow allocation of any unused slots in the slot pool based on the job priority across queues in the slot pool.
For each host used by the pool, define a maximum job slot limit, either in lsb.hosts (MXJ) or lsb.resources (HOSTS and SLOTS).

Configure two pools

The following example configures pool A 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
 
Begin Queue 
QUEUE_NAME = queue2 
PRIORITY   = 48 
SLOT_POOL  = poolA 
SLOT_SHARE = 30 
HOSTS      = groupA 
... 
End Queue
 
Begin Queue 
QUEUE_NAME = queue3 
PRIORITY   = 46 
SLOT_POOL  = poolA 
SLOT_SHARE = 20 
HOSTS      = groupA 
... 
End Queue

The following configures a pool named poolB, with three queues with equal shares, using the hosts in host group groupB, setting a maximum number of slots for the pool (MAX_SLOTS_IN_POOL) and enabling a second round of scheduling based on job priority across the queues in the pool (USE_PRIORITY_IN_POOL):

Begin Queue 
QUEUE_NAME = queue4 
PRIORITY   = 44 
SLOT_POOL  = poolB 
SLOT_SHARE = 30 
HOSTS      = groupB 
MAX_SLOTS_IN_POOL=128
USE_PRIORITY_IN_POOL=Y
... 
End Queue
 
Begin Queue 
QUEUE_NAME = queue5 
PRIORITY   = 43 
SLOT_POOL  = poolB 
SLOT_SHARE = 30 
HOSTS      = groupB 
... 
End Queue
 
Begin Queue 
QUEUE_NAME = queue6 
PRIORITY   = 42 
SLOT_POOL  = poolB 
SLOT_SHARE = 30 
HOSTS      = groupB 
... 
End Queue
