SUMMARY:FaultSight: A Fault Analysis Tool for HPC Researchers
DESCRIPTION:Workshop\n\nFaultSight: A Fault Analysis Tool for HPC Research
 ers\n\nHorn, Fulp, Calhoun, Olson\n\nSystem reliability is expected to be 
 a significant challenge for future extreme-scale systems. Poor reliability
  results in a higher frequency of interruptions in high-performance comput
 er (HPC) applications due to system/application crashes or data corruption
  due to soft errors. In response, application level error detection and re
 covery schemes are devised to mitigate the impact of these interruptions. 
 Evaluating these schemes and the reliability of an application re- quires 
 the analysis of thousands of fault injection trials, resulting in tedious 
 and time-consuming process. Furthermore, there is no one data analysis too
 l that can work with all of the fault injection frameworks currently in us
 e. In this paper, we present FaultSight, a fault injection analysis tool c
 apable of efficiently assisting in the analysis of HPC application reliabi
 lity as well as the effectiveness of resiliency schemes. FaultSight is des
 igned to be flexible and work with data coming from a variety of fault inj
 ection frameworks. The effectiveness of FaultSight is demonstrated by expl
 oring the reliabil- ity of different versions of the Matrix-Matrix Multipl
 ication kernel using two different fault injection tools. In addition, the
  detection and recovery schemes are highlighted for the HPCCG mini-app.\n\
