ok... but do they need to read the full file? I mean, if I have a
3D vector field, each component is a 5 Gb file. I'm opening this in a
cluster, all nodes see the files. Does each node load the 3 files entirely
and then distribute among themselves or it just looks for its part of the
file?
Sorry if the question is dumb... but is the workflow something like:
- read geometry
- partition/distribute geometry/mesh
- only read relevant data to each node from files
?
