Data reduction running time
===

Typical datasets were selected for each powder diffraction instrment to perform a test for the overall running time of the data reduction. Each instrument has its own dedicated section. General users and the instrument team can take a look at their interested instrument for relevant statistics and provide your feedback following the instruction below,

To `vote for your satisfaction` for the overall running time, please go to <a href="https://www.menti.com" target="_blank">www.menti.com</a> and use the code `39496735`.

`If you are not satisfied` with the current running time (given the typical test data being used here, as listed for each instrument in its section), please leave your comments and expected running time for your interested instrument at <a href="https://www.menti.com" target="_blank">www.menti.com</a>, using the code for each instrument, as listed below, respectively,

| Instrument | Code |
|------------|------|
| HB-2A | 59284414 |
| HB-2C | 14260738 |
| NOMAD | 15714322 |
| POWGEN | 3849090 |

## POWDER | HB-2A | HFIR

For HB-2A, the data files involved in the reduction are usually plain text file so the data reduction is indeed flying. For a typical file tested here,

```
/HFIR/HB2A/IPTS-29540/exp894/Datafiles/HB2A_exp0894_scan0004.dat
```

Running time: ~1.5 seconds

> Also, the reduction can be done purely from autoreduction, with all similar runs merged together automatically. By `similar` runs, we mean those repeated measurements under the same condition.

## WAND$^2$ | HB-2C | HFIR

Here follows is a typical file used for testing the HB-2C data reduction running time,

```
/HFIR/HB2C/IPTS-22745/nexus/HB2C_531817.nxs.h5
```

File size: ~25 MB

Running time: ~35 seconds

## NOMAD | BL-1B | SNS

All data files involved here for testing the data reduction running time on NOMAD are listed here,

---

IPTS-28173

<br />

Sample runs: 172544-172549

Empty container runs: 172397-172400

Empty instrument run: 172402

Vanadium run: 172401

<br />

Total size involved: ~50 Gb

---

Absorption correction: method=`SampleAndContainer` for sample and method=`SampleOnly` for vanadium

Running time: ~1.9 minutes

<br />

Absorption correction: method=`None` for sample (i.e., no absorption) and method=`SampleOnly` for vanadium

Running time: ~0.8 minutes

> N.B. The reduction time here refers to the manual reduction where proper caching (via autoreduction)
and calculation of absorption in a group manner is assumed.

## POWGEN | BL-11A | SNS

All data files involved here for testing the data reduction running time on NOMAD are listed here,

IPTS-2767

<br />

Sample runs: 53601

Empty container runs: 51877

Empty instrument run: 52869

Vanadium run: 52863

<br />

Total size involved: ~4 Gb

---

Absorption correction: method=`SampleAndContainer` for sample and method=`SampleOnly` for vanadium

Running time: ~1.0 minutes

Absorption correction: method=`None` for sample (i.e., no absorption correction) and method=`SampleOnly` for vanadium

Running time: ~50 seconds

> N.B. The reduction time here refers to the manual reduction where proper caching (via pre-calculation
for obtaining the absorption workspace) and calculation of absorption in a group manner is assumed.
