SUMMARY:Comparative Study of the Cache Utilization Trends for Regional Sci
 entific Data Caches
DESCRIPTION:Ronak Monga (Indiana University, Lawrence Berkeley National La
 boratory (LBNL))\n\nLarge 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 bandwi
 dth. XCache-based in-network regional data caching system stores scientifi
 c data and can reduce the network traffic and access latency. We examine t
 he established Southern California Petabyte Scale Cache (So Cal Cache) and
  the newly deployed Chicago Regional Cache (Chicago Cache) for a high-ener
 gy physics experiment to analyze cache utilization trends and compare regi
 onal data access patterns. The results of the cache utilization trends sho
 w that the cache contributed to sharing a majority of data, and regional d
 ifferences can be explained by the comparative study. Additionally, predic
 tions of cache behavior show low error values in both regions, providing a
  useful tool for future resource planning.\n\nRegistration Category: Tech
