<p><b>New page</b></p><div>A short glossary of the terms and commands you come across when using Anunna. Where there is a page with more detail, the entry links to it.<br />
<br />
; Apptainer<br />
: The container runtime used on Anunna (formerly Singularity), which runs software packaged as a self-contained image. See [[Apptainer]].<br />
; Bucket<br />
: A snapshot of a compiler-and-toolchain generation (for example <code>2023</code>, <code>2024</code>) that must be loaded before its modules become visible. See [[Environment Modules]].<br />
; Container<br />
: A self-contained software image that bundles an application with its dependencies, so it runs the same anywhere. See [[Apptainer]].<br />
; GRES<br />
: "Generic RESource" — a resource requested with <code>--gres</code>, most often a GPU (for example <code>--gres=gpu:1</code>).<br />
; Job array<br />
: A single submission that creates many near-identical tasks, each with its own <code>$SLURM_ARRAY_TASK_ID</code>. See [[Array Jobs]].<br />
; Login node<br />
: The machine you connect to over SSH; an access point for editing, data transfer, and submitting jobs — not for computation. See [[Login Nodes]].<br />
; Lustre<br />
: The fast, parallel filesystem (mounted at <code>/lustre</code>) used for active compute work. See [[Compute Storage]].<br />
; Module<br />
: A unit of software loaded with <code>module load</code>, provided through the Lmod environment-modules system. See [[Environment Modules]].<br />
; MPI<br />
: The Message Passing Interface, used to run a program across many cores or nodes. See [[Performance Optimization/Multiple nodes (MPI)]].<br />
; NFS<br />
: The network filesystem that hosts home directories — reliable but slower than Lustre. See [[Home Directory]].<br />
; Open OnDemand (OOD)<br />
: The open-source software behind the web portal at apps.anunna.wur.nl. See [[Portal Overview]].<br />
; Partition<br />
: A named set of compute nodes you submit jobs to (<code>main</code>, <code>gpu</code>, <code>gpu_amd</code>). See [[Partitions / Queues]].<br />
; QoS<br />
: "Quality of Service" — a policy attached to your account that governs job priority and resource limits.<br />
; sacct<br />
: SLURM command that reports the accounting record (state, exit code, resource use) of finished jobs. See [[Monitoring Jobs]].<br />
; salloc<br />
: SLURM command that allocates resources for an interactive session.<br />
; sbatch<br />
: SLURM command that submits a batch script as a job. See [[Batch Jobs]].<br />
; Scratch<br />
: Temporary working storage (<code>/lustre/scratch</code>) that is not backed up and may be purged automatically. See [[Compute Storage]].<br />
; .sif<br />
: The Singularity Image Format file that holds an Apptainer container image. See [[Apptainer]].<br />
; sinteractive<br />
: Anunna helper that starts an interactive job (a shell on a compute node). See [[Interactive Jobs]].<br />
; SLURM<br />
: The scheduler that allocates resources and runs jobs on the cluster. See [[Scheduler Overview (Slurm)]].<br />
; squeue<br />
: SLURM command that lists jobs currently known to the scheduler. See [[Monitoring Jobs]].<br />
; srun<br />
: SLURM command that launches a task, or parallel tasks, within an allocation.<br />
; Wall time<br />
: The real-world time limit set on a job with <code>--time</code>; the job is stopped when it is reached.<br />
