SUMMARY:Analyzing the Energy Consumption of Synchronous and Asynchronous C
 heckpointing Strategies
DESCRIPTION:Workshop\n\nAnalyzing the Energy Consumption of Synchronous an
 d Asynchronous Checkpointing Strategies\n\nWilkins, Gossman, Nicolae, Smit
 h, Calhoun\n\nWith exascale computing, the number of components that compr
 ise high-performance computing (HPC) systems has increased by more than 70
 %, leading to a shorter mean time between failure (MTBF) and larger power 
 budgets. These issues induce the need for (1) checkpoint/restart (C/R) and
  (2) energy reduction techniques. C/R has evolved with different software 
 and hardware advances, thus it is crucial to understand how its energy usa
 ge differs under various storage tiers and synchronicity. In this paper, w
 e present a comparison of the energy consumption of leading, state-of-the-
 art C/R libraries, VELOC and GenericIO. We perform weak and strong scalabi
 lity tests of the C/R libraries and show that asynchronous C/R provides 4x
  greater throughput while using 33% less energy than synchronous C/R. Data
  size and throughput are directly correlated to energy consumption. Theref
 ore, C/R developers should focus on ways to improve/maintain high throughp
 ut in order to reduce energy consumption to address exascale needs.\n\nSes
