A.6 Submitting an Interactive Job with LSF

This example shows how to submit a batch interactive job to LSF with the bsub -Ipcommand. When you specify the -Ipoption, bsub submits a batch interactive job and creates a pseudo-terminal when the job starts. A new job cannot be submitted until the interactive job is completed or terminated.
