Thanks, Markus. Seems that the ParallelModuleQueue itself works if it is fed with Module objects, but not if MultiModule objects are put into the queue...
So, I believe I am struggling with the same issue as Luca: https://github.com/OSGeo/grass-addons/pull/523#issue-629160914 Can it be that returns of the MuliModule should be different? If I understand the source code [1] correctly, Module returns "self" (a Module object) while MultiModule returns "None". Can that be the root cause? Any help is much appreciated...

While I have no direct recommendation you may want to check the working code here, in the addons: - t.rast.mosaic - t.sentinel.import - t.sentinel.mask - t.rast.resample See: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fsearch%3Fq%3Dorg%253Amundialis%2BParallelModuleQueue%26type%3Dcode&data=04%7C01%7C%7C61c3f8df57d44d90905108d91fa9435d%7C6cef373021314901831055b3abf02c73%7C0%7C0%7C637575634109191335%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=tbzIS%2FhRmi6hWOAuieoNxubEN73Q8MDmfqHK0wyy7eE%3D&reserved=0 Best, Markus _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-dev
