ECHAM-6.3.05p2 AMIP Experiments: Concurrent vs. Classical Radiation Scheme Performance

Performance measurement results and climate model outputs from Atmospheric Model Intercomparison Project (AMIP) experiments using the ECHAM-6.3.05p2 model. The data compares the computational performance and simulated climate state of a concurrent radiation scheme against the classical scheme. The dataset was created by Mohammad Reza Heidari at Universität Hamburg.

Use Cases

• Benchmarking computational speedup based on the runtime comparisons between concurrent and classical radiation schemes.
• Analyzing MPI process efficiency based on the idle time and data exchange cost metrics.
• Validating climate model fidelity by comparing simulated mean climate states from concurrent and classical schemes against reanalysis and observational data.

Strengths

• Includes direct runtime comparisons for total model execution and the radiation component specifically.
• Provides metrics for parallelization overhead, including data exchange cost and MPI process idle time.
• Contains model output data assessed against reanalysis and observational references for climate state validation.

Limitations

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