It is our great pleasure to welcome you to The 5th Fault Tolerance for HPC at eXtreme Scale (FTXS) 2015 Workshop -- FTXS '15.
This year's FTXS workshop continues its tradition of being a top-quality venue for research and works in progress in the field of fault tolerance and resilience for extreme scale and high performance computing (HPC) systems. The program committee for FTXS 2015 continues the practice of having members from the many varied areas of dependability related to extreme scale computing while also representing academia, industry, government laboratories and government agencies. The PC is also diverse internationally with representatives from the USA, Asia, and Europe.
The call for papers attracted submissions from Asia, Europe, and the United States. The program committee reviewed and accepted the following: Technical Papers Venue or Track Reviewed - 15 Accepted - 9 = 60%
We also encourage attendees to attend the keynote and invited talk presentations. These valuable and insightful talks can and will guide us to a better understanding of the future:

Failures in Large-Scale Systems: Insights from the Field
The use of highly scaled technologies and large component counts pose significant reliability challenges for large-scale systems. Knowledge of failures that occur in such systems is valuable for driving RAS design decisions for component and system ...
A Principled Approach to HPC Event Monitoring
As high-performance computing (HPC) systems become larger and more complex, fault tolerance becomes a greater concern. At the same time, the data volume collected to help in understanding and mitigating hardware and software faults and failures also ...
LogDiver: A Tool for Measuring Resilience of Extreme-Scale Systems and Applications
This paper presents LogDiver, a tool for the analysis of application-level resiliency in extreme-scale computing systems. The tool has been implemented to handle data generated by system monitoring tools in Blue Waters, the petascale machine in ...
Resilient Matrix Multiplication of Hierarchical Semi-Separable Matrices
The hierarchical semi-separable (HSS) matrix factorization has useful characteristics for representing low-rank operators on extreme scale computing systems. To prepare for the higher error rates anticipated with future architectures, this paper ...
Voltage Overscaling Algorithms for Energy-Efficient Workflow Computations With Timing Errors
We propose a software-based approach using dynamic voltage overscaling to reduce the energy consumption of HPC applications. This technique aggressively lowers the supply voltage below nominal voltage, which introduces timing errors, and we use ...
Empirical Studies of the Soft Error Susceptibility ofSorting Algorithms to Statistical Fault Injection
Soft errors are becoming an important issue in computing systems. Near threshold voltage (NTV), reduced circuit sizes, high performance computing (HPC), and high altitude computing all present interesting challenges in this area. Much of the existing ...

In this position paper, we argue for improved fault-tolerance of an MPI code by introducing lightweight virtualization into the MPI interface. In particular, we outline key-value store semantics for MPI send/recv calls, thereby creating a far more ...
How Much SSD Is Useful for Resilience in Supercomputers
We consider the use of non-volatile memories in the form of burst buffers for resilience in supercomputers. Their cost and limited lifetime demand effective use and appropriate provisioning. We develop an analytic model for the behavior of workloads on ...
