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 www.menti.com 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 www.menti.com, using the code for each instrument, as listed below, respectively,
Instrument |
Code |
---|---|
HB-2A |

HB-2C |

NOMAD |

POWGEN |

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
Sample runs: 172544-172549
Empty container runs: 172397-172400
Empty instrument run: 172402
Vanadium run: 172401
Total size involved: ~50 Gb
Absorption correction: method=SampleAndContainer
for sample and method=SampleOnly
for vanadium
Running time: ~1.9 minutes
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
Sample runs: 53601
Empty container runs: 51877
Empty instrument run: 52869
Vanadium run: 52863
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.
