Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Identical independent tasks and dedicated workers; no scheduling or transfer overhead beyond the explicit setup. Zero tasks means zero time.
Example Calculation
- Tasks: 100
- Parallel workers: 8
- Duration per task: 30 s
- One-time setup: 10 s
100 tasks on 8 workers need 13 waves; at 30 s each plus 10 s setup, completion is 400 s.
Frequently asked questions
How do I use this calculator?
Enter tasks, parallel workers, duration per task, one-time setup. The result updates automatically. Use Reset to restore the example values.
What method does it use?
waves=ceil(tasks/workers); completion=setup+waves × task duration.. Identical independent tasks and dedicated workers; no scheduling or transfer overhead beyond the explicit setup. Zero tasks means zero time.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
