◆Standard output (stdout) file name up to 4094 characters for UNIX and Linux or 255 characters for Windows (-o output_file)

◆Standard error (stderr) file name up to 4094 characters for UNIX and Linux or 255 characters for Windows (-e error_file)

◆Overwrite standard output (stdout) file name up to 4094 characters for UNIX and Linux or 255 characters for Windows (-oo output_file)

◆Overwrite standard error (stderr) file name up to 4094 characters for UNIX and Linux or 255 characters for Windows (-eo error_file)

Modified resource usage limits cannot exceed limits defined in the queue.

To modify the CPU limit or the memory limit of running jobs, the parameters LSB_JOB_CPULIMIT=Y and LSB_JOB_MEMLIMIT=Y must be defined in lsf.conf.

If you want to specify array dependency by array name, set JOB_DEP_LAST_SUB in lsb.params. If you do not have this parameter set, the job is rejected if one of your previous arrays has the same name but a different index.

By default, options for the following resource usage limits are specified in KB:

◆Core limit (-C)

◆Memory limit (-M)

◆Stack limit (-S)

◆Swap limit (-v)

Use LSF_UNIT_FOR_LIMITS in lsf.conf to specify a different unit for the limit (MB, GB, TB, PB, or EB).

Modifying resource requirements

The -Roption of bmod completely replaces any previous resource requirement specification. It does not add the modification to the existing specification. For example, if you submit a job with

bsub -R "rusage[res1=1]"

then modify it with

bmod -R "rusage[res2=1]"

the new resource usage requirement for the job is [res2=1], not [res1=1; res2=1].

bmod does not support the OR () operator on the -Roption.

To remove all of the string input specified using the bsub command, use the -Rnoption.

Modifying job groups

Use the -goption of bmod and specify a job group path to move a job or a job array from one job group to another. For example:

bmod -g /risk_group/portfolio2/monthly 105

moves job 105 to job group /risk_group/portfolio2/monthly.

Like bsub -g, if the job group does not exist, LSF creates it.
