Examples

CPU Batch Job

sbatch \
  -J hello \
  -p cpu \
  -c 1 \
  --mem 512M \
  -t 00:05:00 \
  -o logs/%j.out \
  --wrap 'echo hello'

Expected result:

• Submitted batch job <id>
• logs/<id>.out contains hello

GPU Batch Job

sbatch \
  -J gpu-demo \
  -p gpu \
  -c 4 \
  --mem 8G \
  -G 1 \
  -t 01:00:00 \
  -o logs/%j.out \
  --wrap 'nvidia-smi'

Expected result:

• the job runs on the GPU partition
• output contains nvidia-smi data

Interactive Foreground Run

srun --label --unbuffered -- echo hello

Expected result:

0: hello

Interactive Allocation

salloc -p gpu -c 4 --mem 8G -G 1 -t 00:30:00

Expected result:

• Granted job allocation <id>
• a shell starts inside the allocation

Array Job

sbatch \
  -J array-demo \
  -a 0-9%2 \
  -o logs/%A_%a.out \
  --wrap 'echo task=$SLURM_ARRAY_TASK_ID'

Expected result:

• multiple task records
• logs such as logs/<array_id>_0.out

Requeue Once

sbatch --requeue --wrap 'exit 1'

Expected result:

• the first failure returns the job to PENDING
• the second failure leaves the final state as FAILED

Delayed Start

sbatch --begin now+00:10:00 --wrap 'echo delayed'

Expected result:

• the job remains pending until the begin time
• squeue --start shows an estimated future start time

Explicit Export

sbatch \
  --export FOO=bar,HELLO=world \
  --wrap 'echo "$FOO $HELLO"'

Expected result:

• output contains bar world

Manual Daemon Run

SLOTD_ROOT="$HOME/.local/share/slotd" ./target/release/slotd daemon

Then from another shell:

SLOTD_ROOT="$HOME/.local/share/slotd" ./target/release/slotd sbatch --wrap 'echo hello'
