Two system wide environment variables are set on yellowstone for your convenience. CESMROOT and CESMDATAROOT point to
the root cesm directory (currently /glade/p/cesm) and the root cseg directory (currently /glade/p/cesm/cseg) If you are writing scripts
or other code to support running on yellowstone use these environment variables instead of the hard paths to the directories which are
subject to change. Since there are so many precompile options in CESM we do not provide precompiled binaries, you can find source code
for CESM in the directory $CESMROOT/releases. Please refer to the user manual at CESM1.1 Release for
more general instructions.

- Running the release code: The CESM1_1_1 release code is available in $CESMROOT/releases/cesm1_1_1 . Please see the web page at CESM1.1 Known Problems for a list of known problems in this release.
- Running the previous cesm1_0 release: A port of cesm1_0 is provided in $CESMROOT/releases/cesm1_0_5. Users interested in cam5 physics or the cam-se dycore should use the cesm1_1 release or the cesm1_2 development code, not cesm1_0. Please see the CESM 1.0 release page for a list of known problems in this release.
- Running cesm1_2 development code: The latest development code is available in $CESMDATAROOT/collections this code should not be used for science except with the expressed consent of CSEG.
- Running ccsm3: A port of the ccsm3 code is provided in $CESMROOT/releases/ccsm3_0_1_beta33 This port has been tested in a few configurations but no climate validation has been performed.
