Job Arrays

LSF provides a structure called a job array that allows a sequence of jobs that share

the same executable and resource requirements, but have different input files, to be

submitted, controlled, and monitored as a single unit. Using the standard LSF

commands, you can also control and monitor individual jobs and groups of jobs

submitted from a job array.

After the job array is submitted, LSF independently schedules and dispatches the

individual jobs. Each job submitted from a job array shares the same job ID as the

job array and are uniquely referenced using an array index. The dimension and

structure of a job array is defined when the job array is created.

Create a Job Array

A job array is created at job submission time using the -J option of bsub.

1 For example, the following command creates a job array named myArray made

up of 1000 jobs.

bsub -J "myArray[1-1000]" myJob

Job <123> is submitted to default queue <normal>.
