Hello,
I am just starting to look into simulation with liggghts for my studies.
Is there any way to output the distribution of CPU cores in space and is it possible to change the number of CPU cores after startup?
As an example I want 4 cores for filling and 16 for further steps like mixing.
thanks for your help
Phil

dump decomposition/vtk
You can use the
dump decomposition/vtkcommand to output the processor grid decomposition.cf. https://www.cfdem.com/media/DEM/docu/dump.html
The number of cores used (and thus the domain decomposition) may be changed when restarting.
