CostHat Proof-of-Concept Implementation

This is a simple, standalone, proof-of-concept implementation of CostHat in the Python programming language.

Files:

• costhat.py: contains the actual model
• costhat_tests.py: some simple smoke tests and examples
• ucc_casestudy.py: case study implementation, uses the application model specified in ucc_casestudy_model.xml
• ucc_eval.py: evaluation script for scalability of cost evaluation
• numerical_eval.csv: raw data resulting from the scalability evaluation
• generate_plots.py: helper to generate plots from this raw data using ggplot

Usage:

CostHat models can be constructed either via Python program code or in XML. For examples that construct models in Python please refer to costhat_tests.py. A somewhat large example of an XML-based definition is in ucc_casestudy_model.xml, and ucc_casestudy.py shows how to instantiate an XML-based CostHat model in code.
