peak memory (GB)

  • 2.832142336

GPU usage status

  • GPU requested in Slurm allocation

memory calculation method

  • Peak memory: the largest resident memory (Slurm MaxRSS) of any job step, converted from bytes to gigabytes. No average memory: Slurm does not record memory use over time.

energy metric source

  • IPMI power of the compute node read through its Prometheus ipmi_exporter; Slurm acct_gather_energy/ipmi for comparison

energy calculation method

  • Node energy: IPMI power of the node (ipmi_exporter) read about every 10 s while the job ran (8 readings, 322 to 710 W, covering 96% of the job), integrated over time and scaled to the job duration (75 s): 35326 J. The whole node was allocated to this job, so all of it is the job's energy, converted to kilowatt-hours (1 kWh = 3,600,000 J): 0.009813 kWh. For comparison, Slurm accounting (acct_gather_energy/ipmi) reports 41580 J; it reads the power only every 30 sec, which is less precise for a job of this length. Single node hpc-cms01-004 (HPC@HU), allocated entirely to this job (all 256 CPUs). Energy is the measured energy of the whole node, including its idle power; cooling and network are excluded.

carbon calculation method

  • Time-matched: the run's energy 0.009813 kWh x the 15-minute carbon intensity of the grid (Electricity Maps, zone DE, lifecycle, flow-traced) in the quarter-hours the run used, weighted by the run's energy in each quarter-hour (split by power readings; 09:30 UTC 391 g/kWh x 100.0%) = 391.0 g/kWh, so 3.84 g CO2e. Window start and end are Europe/Berlin times. Recalculated on 2026-11-07: replaces the earlier value 3.90 g CO2e (397.0 g/kWh).

idle power method

  • Node hpc-cms01-004 saves energy when nothing runs: its idle processor cores sleep (low-power states), while the node itself stays on and takes new jobs at once. Sleeping idle power: 317 W, the median IPMI power of the node in the cluster monitoring (Prometheus, a reading every 5 s) over the 30 days up to 2026-10-30, counting only times when nothing had run on the node for at least 30 minutes (load below 0.2, both GPUs below 60 W). No energy above idle is given for this run: the node's cores sleep when idle, and its idle power without sleep is not known. The node is assumed to have had its current power profile also on the day of the run.

node CPU utilisation average (%)

  • 7.9

node conditions method

  • Node CPU utilisation: CPU time of all processes on the node (node_exporter, all modes except idle and iowait) / (256 CPUs x sampled time) = 7.9% (20.3 of 256 CPUs busy on average). Node power: IPMI power of the node (ipmi_exporter), 8 readings about every 10 s: average 471 W (over time), lowest 322 W, highest 710 W. CPU efficiency: job CPU time 1456 s / (256 allocated CPUs x 75 s) = 7.6%. Data read and written: Slurm accounting MaxDiskRead and MaxDiskWrite of the job's 1 step(s): 7.584 GB read, 8.703 GB written. This is all data the job's processes read and wrote, on any file system.
