Only one CPU is used about nodemicmac HOT 8 CLOSED

Hello:
You should use this parameter:

  --max-concurrency <integer>
                        The maximum number of cores to use in processing.
                        Default: 4

Certain processes in the pipeline are single threaded won't use more than 1 thread/CPU. For example, the alignment / calibration step and the orthomosaic creation step. Thanks

yea was doing this (with number 32).
But only ever one CPU was used (looked at the CPU rate very often).

One project took about 20 hours. Were with the normal webodm node it would only take 1-2 hours.

Im using a virtual server with 32 CPUs for clarification.

I did several tests:

Using the webgui of WebODM:

• ccd-width: 13.2, max-concurrency: 32, multi-scale: true, ccd-height: 8.8, image-footprint: true, camera-cloud: true

• ccd-width: 13.2, max-concurrency: 32, matcher-distance: 50, ccd-height: 8.8

• Default settings (at least 4 CPUs should have been used here)

Using the webgui of nodemicmac directly:

• ccd-width: 13.2, max-concurrency: 32, multi-scale: true, ccd-height: 8.8, image-footprint: true, camera-cloud: true

All of those attempts never raised the CPU usage above one CPU.

As i said, my setup has 32 CPUs, which are utilized by the odm_node but not on micmac.

Sorry for the late response. Yea i did watched the top command.
I just updated everything again and it might be faster now, i need a few days to observe. Anyway i think there is a lot of potential for further parallelisation, since nodeodm is a lot faster (and uses more CPU time) in comparison.

Latest version of micmac is now in this repository, I closed this one
