Shallow Water Model Simulations Comparing Float16 and Float64 Precision

Four simulation runs compare the performance and accuracy of different numerical precision formats for fluid dynamics. The dataset contains netCDF files presenting velocities, sea surface height, and sea surface temperature from the ShallowWaters.jl model. It was created by researchers from the University of Oxford using the Isambard UK National Tier-2 HPC Service in 2021.

Use Cases

• Benchmarking computational speedup of reduced-precision arithmetic based on the Float16 vs Float64 comparison
• Analyzing error propagation in fluid simulations based on the presence or absence of compensated time integration
• Validating mixed-precision simulation techniques based on the Float16/32 run

Strengths

• Provides a direct comparison of four distinct simulation configurations (Float16 with/without compensation, Float64 reference, Float16/32 mixed)
• Includes detailed model parameters and progress monitoring logs for each run
• Generated using a UK National Tier-2 HPC service, suggesting high-fidelity computational resources

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and total dataset size are unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
