A work around has been introduced for IPSLCM6.0.10-LR : [3193] . Use it carefully ie if you understand these lines.
To have strict reproducibility after a new start from a restart, let use in COMP/opa9.card :

	Reproducibility_after_restart= y

in DRIVER/opa9.driver :

  • force nn_it000=kt red from restart file +1 .
  • force nn_itend (and nn_stock) to : new nn_it000 + previous (nn_itend -nn_it000)
  • kt red from restart file=$(ncdump -v kt restartopa_0000.nc|grep 'kt ='|awk '{print $3}' )
