Using different columns per chunk for Convection and Radiation Routines

Hi, We are working on both CAM4 and CAM5. We are trying fine grain parallelism for convection and coarse grain parallelism for Radiation module. Is it possible to have different columns per chunk (pcols) for Convection and Radiation (let's say in case we want to integrate both the codes)? Thanks,Amlesh

The short answer is no.  All the data structures on the physics side assume a fixed size chunk (pcols) with the actual number of valid columns in the chunk (ncols) variable.  The assignment of columns to a chunk is static and performed by the phys_grid module.  Any changes to this assumption would have far reaching consequences and would require extensive code refactoring.
