14. 14 10. Summary High-energy physics is a good application of e-Science. The e-Science for high-energy physics has three components: data production, data processing and data analysis The system for data processing for CDF experiments is embedded at KISTI. CGCC (CDF Grid Computing Center) is being built at KISTI.
