"Installing" is a bit of a misnomer. One does not install E3SM like system software: in a location such as /usr/local/bin for everyone to use. Instead, a user creates executables for their cases and keeps them in their own directories.
On supported machines (listed on Configuration Management) you can get started running E3SM by following steps 1-8 of the Development Getting Started Guide.
On an unsupported machine:
- it may be necessary to first install some of the software E3SM needs. See Configuration Management. You are on your own but some help is on the pages below.
- Start by porting CIME to your new machine. You'll have to add your machine to CIME's configuration system. See http://esmci.github.io/cime/users_guide/porting-cime.html. You can use the version of CIME that comes with E3SM or check out CIME by itself from https://github.com/ESMCI/cime
- Once you can build CIME-only X and A cases, try building E3SM cases. Then try running the E3SM test suites.
