start time

  • September 21, 2026 3:52 PM

end time

  • September 21, 2026 3:53 PM

duration (s)

  • 47

duration time calculation method

  • Wall-clock interval surrounding the successful Nextflow run command, including orchestration. Precise duration: 47.12435 seconds. Published timestamps use Europe/Berlin, CEST (UTC+02:00).

run status

  • Succeeded

CPU time (s)

  • 8.231308

CPU time calculation method

  • Sum of task realtime multiplied by CPU percentage from the four Nextflow .command.trace records. Nextflow trace/v2 stores realtime in milliseconds and CPU percentage in tenths of a percent; CPU seconds = realtime_ms * raw_cpu / 1,000,000. Includes only the four scientific task processes; excludes the driver and counter reader.

task count

  • 4

pod count

  • 4

peak memory (GB)

  • 0.192524288

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)

  • 0.000622351110238249

energy metric source

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

energy calculation method

  • Whole-node CPU-package energy during the 47.124350-second workflow command interval: 2240.463997 J, converted to kWh by division by 3,600,000. The separately recorded DRAM domain measured 289.840600 J and is not included in this kWh field. Counter samples were collected approximately once per second; microjoule deltas were corrected for wrapping and linearly interpolated at execution boundaries. These whole-node readings include other activity, the driver, and monitoring overhead; they are not exclusive workflow energy. No idle baseline was subtracted.

carbon calculation method

  • Not calculated: no verified carbon-intensity factor was collected for this execution.
