Basic job submission
A basic BSUB job submission command consists of three parts:
| bsub | LSF options | job |
- The BSUB executable command
- LSF options requesting resources and defining job-related options
- A job to be submitted
Here is an example:
| bsub | -n 4 -W 4:00 -R "rusage[mem=4096]" | "python myscript.py" |
Job
A job can be one of the following:
| Job | Command | Examples of job submission command |
|---|---|---|
| a single Linux command | cmd | |
| a program with its path | /path/to/myprogram | bsub ./bin/hello |
| a command or program with its arguments | cmd arg1 arg2 | bsub echo hello |
| multiple commands | "cmd1 ; cmd2" | bsub "date; pwd; ls -l" |
| piped command | "cmd1 | cmd2" | |
| a command with I/O redirection, quote | "cmd<in >out" | bsub "du -sk/scratch > du.out" |
| a here document, passed via "<<" | << EOF ... EOF | |
