Abstract:
The increasing complexity of scientific applications and the increase of scalability in high performance computing systems demand a more powerful Input/Output system. This requirement is present in both performance and power consumption. For this reason, performance, power consumption, energy and energy efficiency have become critical measures in Input/Output systems. Nowadays, when a High Performance Computing center buys a system of storage not only does it take into account the price, but also the cost of its useful life cycle as well as the energy cost. This paper proposes a methodology to characterize the energy efficiency of the Input/Output system, considering the Input/Output system at a device level, I/O library and file system. The methodology provides a wide range of I/O system parameters that have an impact on the energy efficiency. Furthermore, we evaluate the impact of Input/Output intensive applications in energy efficiency.
