The gqueue utility is used to simplify the task of submitting computational jobs to the Sun GridEngine (SGE) queue environment. SGE runs parallel jobs in a special context called a parallel environment. A parallel environment controls how a multi-node job is started and stopped. Serial jobs need not run inside a parallel environment. However, in all cases a job must be submitted to SGE as a queue script: an executable shell script that contains additional commands that influence how SGE will handle the job in addition to the actual commands associated with the computational task. gqueue removes the burden of writing an SGE submission script each time a user wishes to run a calculation: it writes the script for the user.
