In this paper we propose a runtime-based selective task replication technique for task- parallel high performance computing applications. Our selective task replication technique is …
In this paper, we present a non-parametric dataanalytic soft-error detector. Our detector uses the key properties of Gaussian process regression. First, because Gaussian process …
We present FPDetect, a low-overhead approach for detecting logical errors and soft errors affecting stencil computations without generating false positives. We develop an offline …
As machines increase in scale, it is predicted that failure rates of supercomputers will correspondingly increase. Even though the mean time to failure (MTTF) of individual …
With ever-increasing execution scale of parallel scientific simulations, potential unnoticed corruptions to scientific data during simulation make users more suspicious about the …
As high performance computing (HPC) systems continue to grow, their fault rate increases. Applications running on these systems have to deal with rates on the order of hours or days …
Soft errors caused by transient bit flips have the potential to significantly impactan applicalion's behavior. This has motivated the design of an array of techniques to detect …
Hardware errors become more common as silicon technologies shrink and become more vulnerable, especially in memory cells, which are the most exposed to errors. Permanent …

We present FailAmp, a novel LLVM program transformation algorithm that makes programs employing structured index calculations more robust against soft errors. Without FailAmp, an …
