Hi aliceb,

I really glad to see that cesm2.0 is released.  We have successfully downloaded the cesm2.0 in our server (HPC) and trying to install cesm2.0.0 on our Linux (rhel 6.9) HPC system.  Could you please get us the steps to install it in brief or provide me user guide for it. It would be a great help from you if you tell the procedure to be followed with prerequisites and the PGI 2018 compiler.
