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 (66 readings, 450 to 802 W, covering 98% of the job), integrated over time and scaled to the job duration (66 s): 37656 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): 0.010460 kWh. For comparison, Slurm accounting (acct_gather_energy/ipmi) reports 31102 J; it reads the power only every 30 sec, which is less precise for a job of this length. Single node hpc-cms01-024 (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 0.010460 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; 20:00 UTC 448 g/kWh x 100.0%) = 448.0 g/kWh, so 4.69 g CO2e. Window start and end are Europe/Berlin times. Recalculated on 2026-11-07: replaces the earlier value 4.91 g CO2e (469.0 g/kWh).

idle power method

  • Node hpc-cms01-024 does not save energy when nothing runs: its BIOS profile "HPC" (confirmed by the HPC@HU administrators) keeps the processor cores from sleeping. Node idle power: 427 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: 448.2 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 1645539, 2026-10-25, 301 readings). It is almost the same (+21 W) because the cores do not sleep anyway. Energy above idle is the energy above the node idle power.

fan speed average (rpm)

  • 7901.0

node CPU utilisation average (%)

  • 8.7

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) = 8.7% (22.2 of 256 CPUs busy on average). Node power: IPMI power of the node (ipmi_exporter), 66 readings about every 1.0 s: average 571 W (over time), lowest 450 W, highest 802 W. CPU efficiency: job CPU time 1408 s / (256 allocated CPUs x 66 s) = 8.3%. Energy above idle = (node energy 37656 J - 427 W x 66 s) = 9474 J = 0.002632 kWh: the part of the energy that the job caused on top of what the node draws when it does nothing (idle power: see idle power method). CPU frequency: current frequency of the 256 CPUs the job could use (/proc/cpuinfo), 66 readings. At each reading the fastest of these CPUs is taken, because the CPUs that are working run fastest: average 3090 MHz, highest 3139 MHz. Average over all of these CPUs, including idle ones: 2377 MHz. Fan speed: IPMI fan sensors of the node (ipmi_exporter), 6 fans, 66 readings: average 7901 rpm (mean of the fans, over time), highest 8160 rpm. Data read and written: Slurm accounting MaxDiskRead and MaxDiskWrite of the job's 1 step(s): 17.987 GB read, 21.254 GB written. This is all data the job's processes read and wrote, on any file system.
