Algorithm-Based Fault Tolerance for Many-Core Architectures

Modern many-core architectures with hundreds of cores provide a high computational potential. This makes them particularly interesting for scientific high-performance computing and simulation technology. Like all nano scaled semiconductor devices, many-core processors are prone to reliability harming factors like variations and soft errors. One way to improve the reliability of such systems is software-based hardware fault tolerance. Here, the software is able to detect and correct errors introduced by the hardware. In this work, we propose a software-based approach to improve the reliability of matrix operations on many-core processors. These operations are key components in many scientific applications.
