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 1.0 s while the job ran (68 readings, 381 to 765 W, covering 98% of the job), integrated over time and scaled to the job duration (69 s): 34949 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): 0.009708 kWh. For comparison, Slurm accounting (acct_gather_energy/ipmi) reports 40227 J; it reads the power only every 30 sec, which is less precise for a job of this length. Single node hpc-cms01-014 (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 0.009708 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; 20:15 UTC 448 g/kWh x 100.0%) = 448.0 g/kWh, so 4.35 g CO2e. Window start and end are Europe/Berlin times. Recalculated on 2026-11-07: replaces the earlier value 4.55 g CO2e (469.0 g/kWh).

idle power method

  • Node hpc-cms01-014 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: 281 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). Awake idle power: 365.2 W, the average IPMI power with the whole node allocated to an empty job while its power was read once a second on the node (Slurm job 1645537, 2026-10-27, 301 readings). The readings keep the cores from sleeping, so the node draws 84 W more. 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.

fan speed average (rpm)

  • 7897.0

node CPU utilisation average (%)

  • 8.6

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) = 8.6% (22.1 of 256 CPUs busy on average). Node power: IPMI power of the node (ipmi_exporter), 68 readings about every 1.0 s: average 507 W (over time), lowest 381 W, highest 765 W. CPU efficiency: job CPU time 1459 s / (256 allocated CPUs x 69 s) = 8.3%. CPU frequency: current frequency of the 256 CPUs the job could use (/proc/cpuinfo), 68 readings. At each reading the fastest of these CPUs is taken, because the CPUs that are working run fastest: average 3178 MHz, highest 3700 MHz. Average over all of these CPUs, including idle ones: 2015 MHz. Fan speed: IPMI fan sensors of the node (ipmi_exporter), 6 fans, 68 readings: average 7897 rpm (mean of the fans, over time), highest 8400 rpm. Data read and written: Slurm accounting MaxDiskRead and MaxDiskWrite of the job's 1 step(s): 11.972 GB read, 14.425 GB written. This is all data the job's processes read and wrote, on any file system.
