The Global Workflow supporting the Global Forecast System (GFS), the Global Ensemble Forecasting System (GEFS), and the Seasonal Forecast System (SFS) with the [UFS-weather-model](https://github.com/ufs-community/ufs-weather-model). Data assimilation, currently only available for the GFS, is provides by both the [GSI](https://github.com/NOAA-EMC/GSI)- and [GDASApp (JEDI)](https://github.com/NOAA-EMC/GDASApp)-based Data Assimilation systems.
In progress [documentation](https://global-workflow.readthedocs.io/en/latest/) is available.
# Prerequisites
The Global Workflow depends on the following prerequisities to be available on the system:
* Workflow Engines - [Rocoto](https://github.com/christopherwharrop/rocoto) and [ecFlow](https://github.com/ecmwf/ecflow) (for NWS Operations)
* Compiler - Intel classic compiler suite version 2021.x
* Software - NCEPLIBS (various), ESMF, HDF5, NetCDF, and a host of other softwares (see module files under /modulefiles for additional details).
- [Spack-stack](https://github.com/JCSDA/spack-stack) is recommended for the installation of dependent libraries.
## Supported platforms
The Global Workflow currently supports the following machines at the indicated tier.
| HPC | Tier | Notes |
| --------------------------------------- |:----:|:--------------------------------------------------------------------------:|
| WCOSS2
NCO | 1 | GEFS testing is not regularly performed. |
| Hera
NOAA RDHPCS | 1 | |
| Hercules
MSU | 1 | Currently does not support the TC Tracker. |
| Orion
MSU | 2 | The GSI runs very slowly on Orion and the TC tracker is not supported. |
| Gaea C5/C6
RDHPCS | 3 | Currently non-operational following an OS upgrade.
Supported by EPIC. |
| AWS, GCP, Azure
NOAA Parallel Works | 3 | Supported by EPIC. |
**Tier Definitions**
1. Fully supported by the EMC global workflow team. CI testing is regularly performed on these systems, the majority of the global workflow features are supported, and the team will address any platform-specific features, bugs, upgrades, and requests for data.
2. Supported by the global workflow team on an ad-hoc basis. CI tests are supported on these systems, but not regularly performed.
3. No official support by the global workflow team, but may be supported by other entities (e.g. EPIC).
