LSF Version 7.3 - Platform LSF Command Reference

Platform LSF Command Reference 147

To restart a job on another host, both hosts must be binary compatible, run the

same OS version, have access to the executable, have access to all open files (LSF

must locate them with an absolute path name), and have access to the checkpoint

directory.

The environment variable LSB_RESTART is set to Y when a job is restarted.

LSF invokes the

erestart(8) executable found in LSF_SERVERDIR to perform the

restart.

Only the

bsub options listed here can be used with brestart.

bsub, brestart calls the master esub (mesub), which invokes any mandatory

esub executables configured by an LSF administrator, and any executable named

esub (without .application) if it exists in LSF_SERVERDIR. Only esub executables

invoked by

bsub can change the job environment on the submission host. An esub

invoked by

brestart cannot change the job environment.

Options

The following option applies only to brestart.

-f Forces the job to be restarted even if non-restartable conditions exist (these

conditions are operating system specific).

See

bsub(1) for a description of all other options.

Limitations

In kernel-level checkpointing, you cannot change the value of core limit, CPU limit,

stack limit or memory limit with

brestart.
