LSF Version 7.3 - Running Jobs With Platform LSF

◆ Total resident memory usage in KB of all currently running processes in a job
◆ Total virtual memory usage in KB of all currently running processes in a job
◆ Currently active process group ID in a job
◆ Currently active processes in a job
On UNIX, job-level resource usage is collected through PIM.
◆ lsinfo—View the resources available in your cluster
◆ bjobs -l—View current resource usage of a job
◆ SBD_SLEEP_TIME in lsb.params—Configures how often resource usage
information is sampled by PIM, collected by
sbatchd, and sent to mbatchd
Load indices measure the availability of dynamic, non-shared resources on hosts in the
cluster. Load indices built into the LIM are updated at fixed time intervals.
◆ lsload -l—View all load indices
◆ bhosts -l—View load levels on a host
Defined and configured by the LSF administrator and collected by an External Load
Information Manager (ELIM) program. The ELIM also updates LIM when new values
are received.
◆ lsinfo—View external load indices
Built-in resources that represent host information that does not change over time, such
as the maximum RAM available to user processes or the number of processors in a
machine. Most static resources are determined by the LIM at start-up time.
Static resources can be used to select appropriate hosts for particular jobs based on
binary architecture, relative CPU speed, and system configuration.
Two types of load thresholds can be configured by your LSF administrator to schedule
jobs in queues. Each load threshold specifies a load index value:
◆ loadSched determines the load condition for dispatching pending jobs. If a host’s
load is beyond any defined
loadSched, a job will not be started on the host. This
threshold is also used as the condition for resuming suspended jobs.
◆ loadStop determines when running jobs should be suspended.
To schedule a job on a host, the load levels on that host must satisfy both the thresholds
configured for that host and the thresholds for the queue from which the job is being
dispatched.
The value of a load index may either increase or decrease with load, depending on the
meaning of the specific load index. Therefore, when comparing the host load conditions
with the threshold values, you need to use either greater than (>) or less than (<),
depending on the load index.

◆ bqueues -l—View suspending conditions for queues
