A job slot is a position
on a grid node that can accept a single unit of work or SAS process.
Each host has a specified number of available job slots. By default,
each host is configured with a single job slot for each core on the
machine, so a multiple-core machine would have multiple job slots.
For information about specifying job slots for a host, see
Platform
LSF Reference.
You can also use a queue
definition to control the number of job slots on the grid or on an
individual host that are used by the jobs from a queue. The QJOB_LIMIT
parameter specifies the maximum number of job slots on the grid that
can be used by jobs from the queue. The HJOB_LIMIT parameter specifies
the maximum number of job slots on any one host that can be used by
the queue. The following example sets a limit of 60 job slots across
the grid that can be used concurrently by the
normal queue
and a limit of 2 job slots on any host that can be used.
Begin Queue
QUEUE_NAME = normal
PRIORITY = 30
DESCRIPTION = default queue
QJOB_LIMIT = 60
HJOB_LIMIT = 2
End Queue
