Potential improvements to chemistry code
- Mark Richardson's work
- Better use of cache
- OpenMP
- Hyperthreading
- Dynamic allocation of work - threads receive work as they
finish (reduce imbalances)
- Convergence criteria to replace NTZS (substeps for
nucleation/sedimentation). UKCA_COAGWITHNUCL is
currently about a 1/3 of GLOMAP-mode.
