Octave can't read files larger than about 2GB because it uses file
offsets that are integers, which probably are 32 bits on your system.
This is a known problem, but as far as I know, no one is actively
working on fixing it.

I did not know about that limit. Use split in linux to subdivide the csv file
into multiple files less than the 2 GB limit that can be passed to your Octave
script.
