Basic job submission

A basic BSUB job submission command consists of three parts:

bsub LSF options job
  1. The BSUB executable command
  2. LSF options requesting resources and defining job-related options
  3. A job to be submitted

Here is an example:

bsub -n 4 -W 4:00 -R "rusage[mem=4096]" "python myscript.py"

Job

Let's start from the third part, a job can be either

a single Linux command cmd
a program with its path /path/to/myprogram
a command or program with its arguments cmd arg1 arg2
multiple commands "cmd1 ; cmd2"
piped command cmd2"
