Hi Eugene,
carto file is a file with a staic graph topology of your node.
in the opal/mca/carto/file/carto_file.h you can see example.
( yes I know that , it should be help/man list :) )
Basically it describes a map of your node and inside interconnection.
Hopefully it will be discovered automatically someday,
but for now you can describe your node manually.
Best regards
