LSF Version 7.3 - Running Jobs With Platform LSF

◆ lsadmin limshutdown—Shuts down LIM
◆ lsadmin limrestart—Restarts LIM
◆ lsload—View dynamic load values
◆ lshosts—View static host load values
◆ Port number defined in lsf.conf.
External LIM (ELIM) is a site-definable executable that collects and tracks custom
dynamic load indices. An ELIM can be a shell script or a compiled binary program,
which returns the values of the dynamic resources you define. The ELIM executable
must be named
elim and located in LSF_SERVERDIR.
Process Information Manager (PIM) running on each server host. Started by LIM,
which periodically checks on
pim and restarts it if it dies.
Collects information about job processes running on the host such as CPU and memory
used by the job, and reports the information to
sbatchd.
◆ bjobs—View job information
Batch jobs and tasks
You can either run jobs through the batch system where jobs are held in queues, or you
can interactively run tasks without going through the batch system, such as tests for
example.
A unit of work run in the LSF system. A job is a command submitted to LSF for
execution, using the
bsub command. LSF schedules, controls, and tracks the job
according to configured policies.
Jobs can be complex problems, simulation scenarios, extensive calculations, anything
that needs compute power.
◆ bjobs—View jobs in the system
◆ bsub—Submit jobs
A batch job that allows you to interact with the application and still take advantage of
LSF scheduling policies and fault tolerance. All input and output are through the
terminal that you used to type the job submission command.
When you submit an interactive job, a message is displayed while the job is awaiting
scheduling. A new job cannot be submitted until the interactive job is completed or
terminated.
The
bsub command stops display of output from the shell until the job completes, and
no mail is sent to you by default. Use
Ctrl-C at any time to terminate the job.
◆ bsub -I—Submit an interactive job
A command that is not submitted to a batch queue and scheduled by LSF, but is
dispatched immediately. LSF locates the resources needed by the task and chooses the
best host among the candidate hosts that has the required resources and is lightly loaded.
Each command can be a single process, or it can be a group of cooperating processes.
