Job Checkpoint, Restart, and Migration
Making a job checkpointable involves specifying the location of a checkpoint
directory to LSF. This can be done manually on the command line or
automatically through configuration.
Manually making a job checkpointable involves specifying the checkpoint
directory on the command line. LSF will create the directory if it does not exist.
A job can be made checkpointable at job submission or after submission.
Use the -k "checkpoint_dir" option of bsub to specify the checkpoint
directory for a job at submission. For example, to specify my_dir as the
checkpoint directory for my_job:
% bsub -k "my_dir" my_job
Job is submitted to default queue .
Use the -k "checkpoint_dir" option of bmod to specify the checkpoint
directory for a job after submission. For example, to specify my_dir as the
checkpoint directory for a job with job ID 123:
% bmod -k "my_dir" 123
Parameters of job are being changed
Automatically making a job checkpointable involves submitting the job to a
queue that is configured for checkpointable jobs. To configure a queue, edit
lsb.queues and specify the checkpoint directory for the CHKPNT parameter
on a queue. The checkpoint directory must already exist, LSF will not create
the directory.
For example, to configure a queue for checkpointable jobs using a directory
named my_dir:
Begin Queue
...
CHKPNT=my_dir
DESCRIPTION = Make jobs checkpointable using "my_dir"
...
End Queue
