[queue_name] There are two options for queue name: collab or collab-preempt. Both of them have startup priority of 5000. Collab has maximum cores of 262 and maximum walltime of 7 days. There is no resource restrictions for collab-preempt, but note that queues ending in ‘-preempt’ contain jobs that can be interrupted and re-queued by jobs from a higher priority queue.
[dd:hh:mm:ss] This is the maximum allowed running time for your job. dd: days; hh: hours; mm: minutes; ss: seconds.
[name_of_job] This is the name of your job that will be showed in the queue.
[email_address] This is the email address you used to receive the system notice when job begins, aborted or ended.
[module] Load a module. For mpirun this would be the module mpi. For full list of available modules run module available from the command line.
[job_location] This is the address of the folder where your input file is located.
[directory_name] This is the address of the lammps executable.
[lammps_version] This is the build of lammps you want to run. Must be in [directory_name].

This command displays detailed information about a submitted job’s status and diagnostic information that can be useful for troubleshooting submission issues. It can also be used to obtain useful information about completed jobs such as the allocated nodes, resources used, and exit codes. NUIT recommends using the flag ‘–vvv’ or ‘–v –v –v’ to gather additional diagnostic information.
mjobctl -m partition=<partition name> <job number>
This command specifies a partition for a job which is already in the queue. This can be useful if you forget to specify a particular partition in the batch file (or if you want to change the partition, for example from quest3 to quest4), as it allows you to do so without having to delete and resubmit the jobs.
