THE NUMBERS, EXPLAINED
How to use this calculator.
The listed tasks run simultaneously on one worker; expansion and overhead are user-measured assumptions. Does not estimate garbage collection or transient copies.
Start with your inputs
Enter concurrent task partition sizes (mb), in-memory expansion factor (multiple), per-task overhead (mb), worker reserved memory (mb). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Concurrent task partition sizes (MB) | 100,200,300 |
| In-memory expansion factor (multiple) | 2 |
| Per-task overhead (MB) | 50 |
| Worker reserved memory (MB) | 100 |
A worked example
With the example inputs above, task memory requirements (mb) is 250, 450, 650. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Task memory requirements (MB) | 250, 450, 650 |
| Total worker memory requirement (MB) | 1,450 |
How this is calculated
Task memory requirements (MB)
Expand each input partition and add per-task overhead.
Total worker memory requirement (MB)
Add all task requirements and reserved worker memory.
Symbols and units
- a
- Concurrent task partition sizes (MB)
- b
- In-memory expansion factor (multiple)
- c
- Per-task overhead (MB)
- d
- Worker reserved memory (MB)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
The listed tasks run simultaneously on one worker; expansion and overhead are user-measured assumptions. Does not estimate garbage collection or transient copies.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Task memory requirements (MB); Total worker memory requirement (MB). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: The listed tasks run simultaneously on one worker; expansion and overhead are user-measured assumptions. Does not estimate garbage collection or transient copies.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
