However, their shortcomings particularly include defciencies in the achievable positioning and path accuracy. The\r\nbacklash as one of the main issues is well described in the literature and numerous solutions to reduce its negative efects\r\nexist. In contrast, there is a lack of literature regarding the scientifc and systematic analysis of the transmission errors in\r\nrack-and-pinion drives. In this paper, the displacements originating in the drive train of a system with industrial components\r\nare measured under diferent operating conditions. The observed transmission errors are thoroughly analyzed in no-load\r\noperation and their sources are discussed. Subsequent investigations show signifcant load-dependent alterations of the\r\ntransmission errors and direction-dependent characteristics, the causes of which are explained. It is shown, that transmission errors negatively afect the path accuracy of position controlled drives, which is amplifed by excitation of the machine\r\nstructure in certain operating conditions. To address this issue, diferent error compensation concepts are presented.", "doi" : "https://doi.org/10.1007/s11740-021-01090-y", "bibtexKey": "steinle2021experimental" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/292cad6c6d7a90044e7289f504f6f4cf7/clausbraun", "tags" : [ "ABFT","GPGPU","SimTech","algorithm-based","computing","errors","fault","fault-tolerance","myown","scientific","simulation" ], "intraHash" : "92cad6c6d7a90044e7289f504f6f4cf7", "interHash" : "852ec5b9e00df1c4437700418d91759c", "label" : "Efficacy and Efficiency of Algorithm-Based Fault Tolerance on GPUs", "user" : "clausbraun", "description" : "", "date" : "2018-03-19 16:15:07", "changeDate" : "2018-03-19 15:29:40", "count" : 7, "pub-type": "inproceedings", "booktitle": "Proceedings of the IEEE International On-Line Testing Symposium (IOLTS'13)", "year": "2013", "url": "", "author": [ "Hans-Joachim Wunderlich","Claus Braun","Sebastian Halder" ], "authors": [ {"first" : "Hans-Joachim", "last" : "Wunderlich"}, {"first" : "Claus", "last" : "Braun"}, {"first" : "Sebastian", "last" : "Halder"} ], "pages": "240--243","abstract": "Computer simulations drive innovations in science and industry, and they are gaining more and more importance. However, their high computational demand generates extraordinary challenges for computing systems. Typical highperformance computing systems, which provide sufficient performance and high reliability, are extremly expensive.\r\nModern GPUs offer high performance at very low costs, and they enable simulation applications on the desktop. However, they are increasingly prone to transient effects and other reliability threats. To fulfill the strict reliability requirements in scientific computing and simulation technology, appropriate fault tolerance measures have to be integrated into simulation applications for GPUs. Algorithm-Based Fault Tolerance on GPUs has the potential to meet these requirements.\r\nIn this work we investigate the efficiency and the efficacy of ABFT for matrix operations on GPUs.
