Supported Platforms and Compilers

Four levels of support have been defined for UFS applications: pre-configured, configurable, limited-test, and build-only. These levels apply to the following community releases of UFS applications and models:

• UFS Medium-Range Weather Application
• UFS Weather Model

The platforms and compilers that fall into each category are listed below.

NOTE: All testing has been done using Intel 18+ or GNU 8+ compilers.

Support Level 1: Pre-Configured Platforms

Pre-configured platforms are platforms where all of the required libraries for building community releases of UFS models and applications are available in a central place. That means bundled libraries (NCEPLIBS) and third-party libraries (NCEP-external) have both been built. Applications and models are expected to build and run out of the box.

Support Level 2: Configurable Platforms

Configurable platforms are platforms where all of the required libraries for building community releases of UFS models and applications are expected to install successfully, but are not available in a central place. Applications and models are expected to build and run once the required bundled libraries (NCEPLIBS) and third-party libraries (NCEP-external) are built.

Support Level 3: Limited-Test Platforms

On limited-test platforms, the required libraries build and the model builds, but only limited testing has been done with running the model. An attempt has been made, where possible, to use the application workflow to do the runs. In other cases the model has been run using simple canned data. In general, the platforms here are macOS and Linux using the open-source GNU compilers (or a combination of the LLVM clang and GNU gfortran compiler for macOS), and the Intel compilers.

System	Compilers used
Summit	GNU-8.2.0
MacOS Mojave/Catalina	GNU-9.2.0/Clang 9.0.0/ gfortran 9.2.0
Redhat/CentOS Linux 8.x.y	GNU-8.3.1
Redhat/CentOS Linux 7.x.y	GNU-8.2.0
Ubuntu Linux 18.04 LTS	GNU-8.3.0

Support Level 4: Build-Only Platforms

On build-only platforms, the required libraries and model build, but there has been no further testing.
