start time

  • September 22, 2026 9:41 AM

end time

  • September 22, 2026 9:49 AM

duration (s)

  • 523

duration time calculation method

  • Wall-clock interval surrounding the successful Nextflow run command, including orchestration. Precise duration: 522.718957 seconds. Download and preparation are excluded. Display timestamps use Europe/Berlin, CEST (UTC+02:00).

run status

  • Succeeded

CPU time (s)

  • 7.386789e+02

CPU time calculation method

  • Sum of task process realtime multiplied by CPU utilization from the four Nextflow task traces. TSV realtime is milliseconds and CPU percentage is normalized: CPU seconds = realtime_ms * percent_cpu / 100,000. Excludes the driver and counter reader.

task count

  • 4

pod count

  • 4

peak memory (GB)

  • 4.856054e-01

GPU usage status

  • CPU-only workflow run; no GPU was requested or used.

memory calculation method

  • Largest observed task peak RSS from the four Nextflow task traces; tasks ran sequentially. RSS bytes divided by 1,000,000,000 for GB. This is a sampled task-memory peak, excludes the driver, and does not measure time-averaged memory.

energy consumed (kWh)

  • 1.084073e-02

carbon emission (kg CO2e)

  • 0.004323793032141491

carbon intensity (kg CO2e/kWh)

  • 0.3988470363288719

energy metric source

  • Intel RAPL powercap energy_uj counters; package-0 and dram domains

energy calculation method

  • RAPL CPU-package energy: 39,026.641 J ÷ 3,600,000 = 0.010840734 kWh over 522.719 seconds, with counter-wrap correction and boundary interpolation. Includes all node activity; excludes DRAM. No idle baseline subtracted.

carbon calculation method

  • Time-matched: the run's energy 0.010841 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 time; 2026-09-22 07:30 UTC 409 g/kWh x 43.6%, 2026-09-22 07:45 UTC 391 g/kWh x 56.4%) = 398.8 g/kWh, so 4.32 g CO2e. Window start and end are Europe/Berlin times. Recalculated on 2026-11-07: replaces the earlier value 5.11 g CO2e (471.0 g/kWh, unknown source).
