  • Fix non bit-for-bit for C/CD with different decompositions. Fixed two issues now noted in C/CD not bit-for-bit with different decomps CICE-Consortium/CICE#700, gridcell / land block elimination stencil for C/CD and maskhalo_dyn problem for C/CD. These need to be looked into further once the C/CD implementation is finalized and stencil is clearer.

  • Fix C/CD exact restart issue, now restarts pass with C/CD. Was an issue in the query_field implementation. Closes C/CD restarts CICE-Consortium/CICE#684

  • Add 2 day restart test, restart2

  • Update test suites

  • Add histdbg option turning on a bunch of history fields, some every timestep

  • Adjust some indentation and other minor changes

  - modify gridcell + land block elimination for C/CD, using a larger stencil, needs to be investigate further
  - turn off maskhalo_dyn for C/CD, needs to be investigated further
- Update omp_suite and gridsys_suite to extend testing
- Add new histdbg option to turn on some output at each timestep to help debugging
- Add 2 day restart test, restart2
