Finite Volume CAM in CCSM

[m_shivi84@gmail_com]

I would like to run CCSM with a 2D decomposition for FV CAM.
The default (1D) decomposition works but can use only upto 30 processors (lats per task >3) for the 2x2.5_gx1v3 resolution.
Can someone help?

Which version of the code are you using, what platform are you running on and how many processes due you
want to run on?

Two systems:
(i) AMD Opteron Linux (64 processors)
(ii) IBM Regatta AIX (128 processors)

I would specifically like to know if it is OK to modify CAM namelist variables like npr_yz in CCSM? Modification of npr_yz led to surfrd error in land (CAM latitude and lsm input latitude has difference too large).
