|
Major goal of the Four-Dimensional Data Assimilation project is to ensure smooth transition of NASA Data Assimilation Office operations to future scalable HPC platforms.
|
This involves:
-
An examination of the potential for parallelization and scalability of operational algorithms at DAO,
-
An examination of the potential for parallelization and scalability of candidate future algorithms at DAO, and
-
Porting and benchmarking of existing codes on testbed parallel architectures.
|
At NPAC, these tasks were associated with the following components of the complete assimilation system:
-
Operational Mini-Volume Optimal Interpolation Analysis (OI)
-
Advection Algorithms for transport and GCM (Eulerian and Semi-Lagrangian)
|
|
Major conclusion: HPF is one of the most relevant technologies for future computing needs at DAO
|
|
DAO is developing a new assimilation system, Physical Space Analysis System (PSAS). NPAC will collaborate with DAO on developing HPF implementation of the production PSAS software.
