Supported Platforms and Compilers

Four levels of support have been defined for the UFS Short-Range Weather (SRW) App. The four testing level definitions are:

• Level 1 (Preconfigured): Libraries built and available in central location, code builds, full testing of model
• Level 2 (Configurable): Libraries and code builds (but no central location for the libraries), full testing of model
• Level 3 (Limited test platforms): Libraries and code builds, limited testing of the model
• Level 4 (Build only platforms): Libraries and code build, no tests with running the model

Generally, Level 1 & 2 systems are restricted to those with access through NOAA and its affiliates. These systems are named (e.g., Hera, Orion, Derecho). Level 3 & 4 systems include certain personal computers or non-NOAA-affiliated HPC systems.

Support Level 1: Pre-Configured Platforms

Pre-configured platforms are platforms where all of the required software libraries for building community releases of UFS models and applications are available in a central place via spack-stack. Applications and models are expected to build and run out of the box. Users must have access to these systems in order to use them.

* Requires NOAA CAC or username/password access

Support Level 2: Configurable Platforms

Configurable platforms are platforms where HPC-Stack or spack-stack are not available in a centralized location but are expected to install successfully. Applications and models are expected to build and run once the required software stack is built. Users must have access to these systems in order to use them.

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.

Support Level 4: Build Only Platforms

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