@inproceedings{347, abstract = {{Dynamic thread duplication is a known redundancy technique for multi-cores. The approach duplicates a thread under observation for some time period and compares the signatures of the two threads to detect errors. Hybrid multi-cores, typically implemented on platform FPGAs, enable the unique option of running the thread under observation and its copy in different modalities, i.e., software and hardware. We denote our dynamic redundancy technique on hybrid multi-cores as thread shadowing. In this paper we present the concept of thread shadowing and an implementation on a multi-threaded hybrid multi-core architecture. We report on experiments with a block-processing application and demonstrate the overheads, detection latencies and coverage for a range of thread shadowing modes. The results show that trans-modal thread shadowing, although bearing long detection latencies, offers attractive coverage at a low overhead.}}, author = {{Meisner, Sebastian and Platzner, Marco}}, booktitle = {{Proceedings of the 10th International Symposium on Applied Reconfigurable Computing (ARC)}}, editor = {{Goehringer, Diana and Santambrogio, MarcoDomenico and Cardoso, JoĆ£oM.P. and Bertels, Koen}}, pages = {{283--290}}, publisher = {{Springer}}, title = {{{Thread Shadowing: Using Dynamic Redundancy on Hybrid Multi-cores for Error Detection}}}, doi = {{10.1007/978-3-319-05960-0_30}}, year = {{2014}}, }
