Comparative Study of the Cache Utilization Trends for Regional Scientific Data Caches

DescriptionLarge scientific collaborations often have many users accessing the same data files, creating repeated file transfers over long distances. Data accesses to the distant data sources cause long latency to the applications and can be further delayed due to limited network bandwidth. XCache-based in-network regional data caching system stores scientific data and can reduce the network traffic and access latency. We examine the established Southern California Petabyte Scale Cache (So Cal Cache) and the newly deployed Chicago Regional Cache (Chicago Cache) for a high-energy physics experiment to analyze cache utilization trends and compare regional data access patterns. The results of the cache utilization trends show that the cache contributed to sharing a majority of data, and regional differences can be explained by the comparative study. Additionally, predictions of cache behavior show low error values in both regions, providing a useful tool for future resource planning.
