2.5.1. Data Structure

Data from execution of experiments ends up under the subdirectory data/. It is often convenient to let data/ be a softlink to a directory on a dedicated disk system (e.g. a Luster file system on a cluster, or an external disk drive on a workstation or laptop). When using the default input file (input.nml) data is stored directly in data/, while if using e.g. run.nml, the data is stored in data/run/.

Metadata describing the snapshots is stored as namelists in files such as

data/params.nml
data/00000/snapshot.nml
data/00000/rank_00000_patches.nml

The binary data may, depending on I/O method, reside in files such as:

data/snapshots.dat
data/00000/snapshot.dat
data/00000/00000.dat
