Hardware/Software Configuration
Supported Machines
E3SM is supported for all users of the following platforms
Perlmutter at NERSC
Frontier at OLCF
Polaris at ALCF
Supported machines that are for E3SM-project staff only.
Compy at PNNL
Chrysalis and Anvil at ANL
Other machines
In general, E3SM should run well on any cluster with a fast network (e.g. Infiniband, not just ethernet).
E3SM is highly configurable and its possible to define cases (such as single column) that will run on a laptop or workstation.
The per-node memory requirements depend on the resolution and components used.
Software prerequisites
The following are the external system and software requirements for installing and running E3SM. (Started from CESM1.2 pre reqs.)
UNIX-style operating system such as CNL, AIX and Linux
csh, bash shells
A recent version of the Perl scripting language (5.16+), plus the following modules:
XML::SAX (from LibXML module)
XML::SAX::Exception ( from the LibXML module)
Switch (Switch.pm)
subversion client version 1.4.2 or greater (for downloading CESM-originating data files)
Git version 2.0 or newer (for getting source code)
Fortran (2003 support required) and C/C++ compilers.
MPI (although E3SM does not absolutely require it for running on one processor)
One or both of (NetCDF-C 4.4.0, NetCDF-Fortran 4.5.0 and/or PNetCDF 1.12 or newer. (E3SM can use PnetCDF if NetCDF is not installed).
CMake 3.18 or newer is required
Python 3.10 or newer is required for E3SM-specific build/test scripts.
OPTIONAL packages that may be required for some configurations.
Supported Compiler Versions
The second column is the versions E3SM uses in its nightly testing. Different machines have different versions.
NOTE: we see lots of variation in model behavior between compiler versions. If you don’t have exactly the same compiler version as what we are testing, you may encounter problems that we can’t help with.
The third column lists test suites we run for each compiler-version matched by color. We do not run all suites with all compiler versions because of the expense and time involved.
