Testing cluster processing of a 3,927 image dataset on different numbers of Intel NUCs (installed via POSM). Parameters adjusted:
min-num-features: 9000, split: 500, split-overlap: 120
The log output has a timestamp when it starts extracting EXIF (after uploading and resizing) and after the merge stage (before postprocessing generation of base and overview tiles). This seems to be shown in the WebODM dashboard listing a longer duration than what is calculated with the timestamps. However, for the 4x POSM dataset the difference is over 10 hours. Additionally the WebODM dashboard duration for the 4x is longer than for the 2x.
- What might be responsible for the outlier 10 hour difference and out of order processing time?
- I will probably rerun the 1x and 2x tests on NUC6i7KYK to remove the variation due to NUC model. Although it’s my understanding that the two should be comparable when it comes to running ODM? The specs for the the NUC8i7BEH1 and the NUC6i7KYK. All have 32GB RAM installed.
- Separately, would it be possible to make the products ready before postprocessing (i.e. the TIFF) available for download as soon as they are ready?
