Submitting a Simple Job Script with LSF-HPC

This example submits a job script (myjobscript.sh) with the bsub -Ioption. Inside the script, there are two srun commands. The first command displays the host name and second command displays system information.

In this example, the run-time environment is first explored. Next, the contents of the myjobscript.sh script is displayed. Then an example of a command to launch the script is shown. Finally, the resulting output of the script is provided.
