2.1 What is needed to run CSIM?

A number of target architectures are supported for CCSM including IBM SP, SGI Origin, SGI Altix, Linux, NEC Earth Simulator, Cray X1, and Compaq ES. The resources required to run CSIM coupled in CCSM are listed in the CCSM3 User's Guide at:

http://www.cesm.ucar.edu/models/ccsm3.0/ccsm.
Two target architectures are supported for uncoupled CSIM: IBM and SGI. Below is a list of what is required to run CSIM uncoupled:

• Operating System: IBM AIX, or SGI IRIX64
• Tools: gunzip, gnumake
• Compilers: Fortran90, C
• Permanent disk space
• Temporary disk space
• Libraries: MPI, netCDF
• Input Data : 10.86 MB for gx3v5 grid
• CSIM source code: 0.83 MB
• Atmospheric Forcing Data : 2.7 GB for gx3v5 grid
