    v20 v21  
    4646* identified that the old and the new drivers have the reversed order of latitude when writing the restart file 
    4747* Global spinup simulations over 400 years are done by using the new driver (thanks to Matt) 
    48 * In spring 2021, Matt mentioned the speed of simulation by using the new driver, compared to the old one. Some profiling tests were applied to the simulations by using new and old drivers. In PARAM/run.def dt_sechiba =1200 is responsible for most of the slowness of the new driver. The value of this parameter depends on user's need. The smaller, the slower, with higher-resolution of time steps in the simulation. 
     48* In spring 2021, Matt mentioned the speed of simulation by using the new driver, compared to the old one. Some profiling tests were applied to the simulations by using new and old drivers. In PARAM/run.def, dt_sechiba =1200 was found to be responsible for most of the slowness of the new driver. The value of this parameter depends on user's need. The smaller value, the slower computation, but with more time steps during the simulation. 
    4949* In summer 2021, a new ticket http://forge.ipsl.jussieu.fr/orchidee/ticket/786 was submitted concerning a problem of the new driver when using the compressed forcing file. By using the latest version of compressed forcing file CRU JRA v2.2, small modification were applied and tested. The new driver now works with the compressed forcing file such as CRU JRA 0.5 degree. But the new driver does not work with the older version of CRU JRA v2.1 0.5 degree due to some inconsistency between land variable and contfrac.  
    5050* In summer 2021, the new driver in Tag 2.2 is updated by Agnes.
