Getting Started

Before running HAFS, users should determine which of the four levels of support is applicable to their system. Generally, Level 1 & 2 systems are restricted to those with access through NOAA and its affiliates. These systems are named (e.g., Hera, Orion). Level 3 & 4 systems include certain personal computers or non-NOAA-affiliated HPC systems. Currently, HAFS level 1 systems are: wcoss_dell_p3, wcoss_cray, hera, jet, and orion. There are no supported level 2-4 systems, but users can likely modify code to run on other systems.

The Quick Start Chapter in the User's Guide is an excellent place for new users to begin. It provides details on how to clone the HAFS App, build it, and run it.

Levels of Support

Four levels (or tiers) of support have been defined for Unified Forecast System (UFS) applications, and HAFS operates under this paradigm:

• Level 1 (Pre-configured): Prerequisite software libraries are pre-built and available in a central location; code builds; full testing of model.
• Level 2 (Configurable): Prerequisite libraries are not available in a centralized location but are expected to install successfully; code builds; full testing of model.
• Level 3 (Limited-test platforms): Libraries and code build on these systems, but there is limited testing of the model.
• Level 4 (Build-only platforms): Libraries and code build, but running the model is not tested. Before running the UPP, users should determine which of the four levels of support is applicable to their system. Generally, Level 1 & 2 systems are restricted to those with access through NOAA and its affiliates. These systems are named (e.g., Hera, Hercules).

Supported Systems

Currently, HAFS support is only available for Level 1 (or "Tier-1") platforms. HAFS Level 1 platforms are:

• Orion
• Jet
• Hera
• WCOSS Dell
• WCOSS Cray

Note that EMC performs testing on WCOSS Dell/WCOSS Cray platforms to ensure operational readiness; however, no community support is available on these machines.
