Tender Details

The National Oceanic and Atmospheric Administration-s (NOAA) Acquisition and Grants Office, Eastern Acquisition Division-Kansas City intends to negotiate and award a purchase order, on a sole source basis, under authority of RFO FAR 6.103-1, with small business entity IC Weather LLC for integration and development of MPAS atmospheric dynamical core within the existing PyTorch framework for the NWS Office of Modeling and Development in Silver Spring, MD.
Sole Source Justification:
The sole source determination is based on NOAA-s Sole Source Justification. Only one source is capable of providing the supplies or services required at the level of quality required because the supplies or services ordered are unique or highly specialized. The specific requirement is to adapt the MPAS dynamical core to leverage GPU acceleration for improved compute efficiency, integration into an infrastructure that enables future work on model parameterizations based on machine learning (ML) algorithms, and provides direct access to parameter gradients which may be used to extend NOAA-s data assimilation (DA) capabilities to
4-Dimensional Varational algorithms (4DVAR) as well as enable advanced observation impact studies including Forecast Sensitivity to Observation Impact (FSOI) techniques. The first of these requirements is capable of being met through a proprietary software package that has integrated MPAS into the PyTorch framework. The vendor has demonstrated via the “MPAS-PyTorch” a substantial decrease in the computational time to run a forecast compared with the current FORTRAN version of MPAS. The nature of integration will allow for further testing at higher spatial resolutions that would meet NWS operational requirements, in conjunction with PyTorch / ML versions of physics schemes used in MPAS to further improve computational efficiency, and use of the native gradients computed by PyTorch for 4DVAR and FSOI capabilities.
Since this initial capability exists, it is ...
