Utility-based High Performance Digital Library Systems
Many practical digital library systems have had to deal with scalability of data collections and/or service provision. Early attempts at enabling this scalability focused on data/services closely coupled with or tightly integrated with various high performance computing platforms. This inevitably resulted in compromises and very specific solutions. This paper presents an analysis of current high performance systems and motivates for why utility computing can subsume existing models and better meet the needs of generic scalable digital library systems.
