About job file spooling
Specifying job input files
LSF enables spooling of job input, output, and command files by creating
directories and files for buffering input and output for a job. LSF removes these
files when the job completes.
You can make use of file spooling when submitting jobs with the -is and -Zs
options to bsub. Use similar options in bmod to modify or cancel the spool file
specification for the job. Use the file spooling options if you need to modify or
remove the original job input or command files before the job completes.
Removing or modifying the original input file does not affect the submitted job.
File spooling is not supported across MultiClusters.
Use the bsub -i input_file and bsub -is input_file commands to get
the standard input for the job from the file path name specified by input_file.
The path can be an absolute path or a relative path to the current working
directory. The input file can be any type of file, though it is typically a shell
script text file.
LSF first checks the execution host to see if the input file exists. If the file exists
on the execution host, LSF uses this file as the input file for the job.
If the file does not exist on the execution host, LSF attempts to copy the file
from the submission host to the execution host. For the file copy to be
successful, you must allow remote copy (rcp) access, or you must submit the
job from a server host where RES is running. The file is copied from the
submission host to a temporary file in the directory specified by the
JOB_SPOOL_DIR parameter in lsb.params, or your $HOME/.lsbatch
directory on the execution host. LSF removes this file when the job completes.
The -is option of bsub spools the input file to the directory specified by the
JOB_SPOOL_DIR parameter in lsb.params, and uses the spooled file as the
input file for the job.
Use the bsub -is command if you need to change the original input file
before the job completes. Removing or modifying the original input file does
not affect the submitted job.
Unless you use -is, you can use the special characters %J and %I in the name
of the input file. %J is replaced by the job ID. %I is replaced by the index of
the job in the array, if the job is a member of an array, otherwise by 0 (zero).
The special characters %J and %I are not valid with the -is option.
