The Design Document page provides a description of the algorithms, implementation and planned testing including unit, verification, validation and performance testing. Please read Step 1.3 Performance Expectations that explains feature documentation requirements from the performance group point of view.

Planned Verification and Unit Testing
Verification and Unit Testing: Expert Review
Date last modified:
Contributors:
The named experts provided extensive review of each other's work, to verify that the design and implementations met the stated requirements. Model testing at each stage of implementation was used to verify that intended changes were correctly implemented, and that unintended changes were avoided.
Planned Validation Testing
Validation Testing: Evaluation
with iESM developed diagnostic scriptsof data exchanged between components

The results of the ported code will eventually be analyzed in a similar manner to that of the iESM (e.g., Thornton et al., 2017). We will not expect exact matches, since we are using a different ESM, but we can ensure the behavior matches expectations/previous experience. For this code review, we will use a set of short test simulations and examine the inputs, outputs, and logs of all components to ensure that the information is being passed correctly in each configuration. We will document the exact checks and archive the code when possible so this can be replicated later.
Planned Performance Testing
Performance Testing: Short simulations on multiple platforms

We do not expect GCAM to alter the performance of the coupled system, but we will perform short coupled simulations on multiple platforms to quantify the change.
