Aims of UKESM-fast
How we'll speed up model
Properties of speed-up
Where does hybrid fit in?
Measuring speed-up
Compiling with 'high'
Increase timestep
Reducing vertical levels
Calling UKCA & radiation less often
Advecting fewer chemistry fields
Reduce time in chemistry solver
Reduce time in aerosol solver
Reduce nwbins for UKCA_ABDULRAZZAK_GHAN
Any more speed-ups?
Concurrent threading and sharing 2nd thread
Hybrid latest
H2O feedback
Hybrid test jobs
Properties of speed-up
Each speed-up will match one of the following
Linear gain
Reducing gains
Increasing gains
