How does XIOS manage the "multiple_file" output ?

Hi,

Curiosity question :
I noticed that using xios in "attached mode" with "multiple file" option, the output files does not correspond to the domain decomposition used for the simulation.
For example using 5 x 5 subdomains for the simulation, xios will create 25 files but not in the "shape" than the defined subdomain shape.
The recombination of the files looks OK.

Thanks,
Sébastien

Hi Sebastien,

Domain decomposition on client and server are different.
Client decomposition is driven by models but server decomposition is driven by IO writing efficiency.

So it is normal.
