Description

This is a first step to make EDA workflow run within SWELL framework. These 32 ensemble members from @rtodling run independently on each node. Both GSI B and all observation type from 3dvar-atmos are used here. The single node run for each member is made possible with the current setting: C90 resolution using thinned observations (rejecting 80% of obs at random).
The memory usage on each node is roughly 72% (There are still details to work out and improve).

To run this code:

swell create eda -o override.yaml -p nccs_discover_sles15
swell launch ...
[override.yaml contains experiment_root and experiment_id]

Example output: T mean increment at 500 hPa :
inc_t_500

The work is advised by @rtodling.
@mranst makes the flow.cylc loop work for ensemble members.
