qsub [-l resources] [-q queue] [-N name] [-o output] script

qsub submits batch jobs to TORQUE or PBS (Portable Batch System) queue managers. It's used in high-performance computing clusters to schedule jobs for execution when resources become available.
Jobs are scripts that specify resource requirements and commands to execute. The queue manager allocates nodes, CPUs, and memory according to the request.

-l _resource_=_value_

Request resource (walltime, nodes, mem, etc.)

Submit to specific queue

Email on events (b=begin, e=end, a=abort)

Resource limits vary by queue and cluster configuration. Jobs may wait in queue for available resources. Exceeding walltime kills the job. Environment variables may not be inherited.

qsub originated with PBS (Portable Batch System) developed at NASA. TORQUE is an open-source derivative. Similar commands exist in Slurm (sbatch) and other job schedulers.
