TimeCap: Methodology for Comparing IT Infrastructures Based on Time and Capacity Metrics

摘要: Scientific community is one of the major driving forces for developing and utilizing IT technologies such as Supercomputers Grid. Although, main race has always been bigger faster infrastructures, an easier access to infrastructures in recent years created a demand more customizable scalable environments. However, introducing new paradigms Cloud computing requires comprehensive analysis its benefits before actual implementation. In this paper we introduce TimeCap, methodology comparing based on time requirements resource capacity wastage. We go beyond just execution by Time Complexity part used arbitrary related tasks required completing procedure, i.e., obtaining scientific results. Moreover, wastage compared using Discrete Capacity, second TimeCap analyzing assignment utilization. evaluate our traditional physical infrastructure local resources. use real world application calculating plasma instabilities computation.
