The act of sharing or passing data between processes has been identified as a well-known challenge in concurrent programming. Concurrent data access on multi-core processors has the potential to result in data inconsistencies when multiple processes concurrently read and write data. As demonstrated in the existing literature, there are multiple methodologies for concurrent data access. In the context of real-time systems, the property of wait-freeness, which guarantees time-bounded access to data, is paramount. This property enables access to shared data that is not dependent on the scheduler. In this paper, we analyze wait-free data structures for two common communication patterns: single-shared-value and firms-in-first-out queues. A comparison of suitable approaches is facilitated by implementing them in Rust and conducting a benchmarking analysis. The benchmark reveals discrepancies in performance that are primarily attributable to cache interference. The findings of this study demonstrate that triple buffers are characterized by wait-free operation and are well-suited for single-shared-value queues. The wait-free FastForward queue is a suitable FIFO queue that also performs optimally in our benchmarks.", "isbn" : "978-3-032-03698-8", "bibtexKey": "10.1007/978-3-032-03698-8_22" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/233592b3c1fb954821eff2d11494bee07/isw-bibliothek", "tags" : [ "Communication","Real-Time" ], "intraHash" : "33592b3c1fb954821eff2d11494bee07", "interHash" : "2a85eb00ff28c41c893d00bcab5a56bd", "label" : "Rescheduling zyklischer Echtzeitkommunikation", "user" : "isw-bibliothek", "description" : "", "date" : "2024-12-13 11:55:13", "changeDate" : "2024-12-13 11:55:13", "count" : 1, "pub-type": "article", "journal": "Zeitschrift für wirtschaftlichen Fabrikbetrieb", "year": "2024", "url": "https://doi.org/10.1515/zwf-2024-1161", "author": [ "Christian von Arnim","Oliver Riedel" ], "authors": [ {"first" : "Christian", "last" : "von Arnim"}, {"first" : "Oliver", "last" : "Riedel"} ], "volume": "119","number": "12","pages": "924--928", "doi" : "doi:10.1515/zwf-2024-1161", "bibtexKey": "vonArnim_Riedel+2024+924+928" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/282f27f99cd20ac6c807068ea6b348e45/tiger", "tags" : [ "streaming","analytics","real-time","twitter","visualisation","vis-gis","vis","vis(us)","visus:ertl","visus:kochsn","visus:knittejs","visus:tangtn","visus:chenwi","visus:wuyi","visus:liusa","tiger-generation:638684700229105045" ], "intraHash" : "82f27f99cd20ac6c807068ea6b348e45", "interHash" : "c007deab89e44502ee765d6b5a60bfdf", "label" : "Real-Time Visual Analysis of High-Volume Social Media Posts", "user" : "tiger", "description" : "", "date" : "2024-11-29 10:41:00", "changeDate" : "2024-11-29 10:41:00", "count" : 6, "pub-type": "article", "journal": "IEEE Transactions on Visualization & Computer Graphics","publisher":"IEEE Computer Society","address":"Los Alamitos, CA, USA", "year": "2022", "url": "", "author": [ "Johannes Knittel","Steffen Koch","Tan Tang","Wei Chen","Yingcai Wu","Shixia Liu","Thomas Ertl" ], "authors": [ {"first" : "Johannes", "last" : "Knittel"}, {"first" : "Steffen", "last" : "Koch"}, {"first" : "Tan", "last" : "Tang"}, {"first" : "Wei", "last" : "Chen"}, {"first" : "Yingcai", "last" : "Wu"}, {"first" : "Shixia", "last" : "Liu"}, {"first" : "Thomas", "last" : "Ertl"} ], "volume": "28","number": "1","pages": "879-889", "orcid-numbers" : "Koch, Steffen/0000-0002-8123-8330, Ertl, Thomas/0000-0003-4019-2505", "affiliation" : "Knittel, Johannes, Institut für Visualisierung und Interaktive Systeme.

The aim of this work is to enhance modeling capabilities when numerical simulations are used as design tools.", "language" : "eng", "doi" : "https://doi.org/10.1016/j.cad.2021.103158", "bibtexKey": "suzuki2021generic" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/283b888adc4b029227d9b7e97896f3ec0/isw-bibliothek", "tags" : [ "GPU","Industrial","Manufacturing","PLC","Real-time","Reinforcement","control","isw","learning","myown" ], "intraHash" : "83b888adc4b029227d9b7e97896f3ec0", "interHash" : "a39b6465c0a777b3cbd24ec6b0425355", "label" : "Reinforcement learning methods based on GPU accelerated industrial control hardware", "user" : "isw-bibliothek", "description" : "", "date" : "2021-03-19 15:13:44", "changeDate" : "2022-01-13 08:22:37", "count" : 2, "pub-type": "article", "journal": "Neural Computing and Applications", "year": "2021", "url": "https://link.springer.com/article/10.1007/s00521-021-05848-4", "author": [ "Alexander Schmidt","Florian Schellroth","Marc Fischer","Lukas Allimant","Oliver Riedel" ], "authors": [ {"first" : "Alexander", "last" : "Schmidt"}, {"first" : "Florian", "last" : "Schellroth"}, {"first" : "Marc", "last" : "Fischer"}, {"first" : "Lukas", "last" : "Allimant"}, {"first" : "Oliver", "last" : "Riedel"} ], "doi" : "https://doi.org/10.1007/s00521-021-05848-4", "bibtexKey": "schmidt2021reinforcement" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2cbd2234dae6a5e34ce03a391a835d168/ingmarkallfass", "tags" : [ "Ground","SAR","SAR;","UAV;","airborne","based","camera;","mmWave;","monitoring;","multi","real-time","sensor;" ], "intraHash" : "cbd2234dae6a5e34ce03a391a835d168", "interHash" : "15ad4325b80fb0ee45728344ba07713a", "label" : "Implementation of a 35 \\GHz\\ \\SAR\\ sensor and a high resolution camera to enable real-time observation", "user" : "ingmarkallfass", "description" : "", "date" : "2020-09-07 14:26:58", "changeDate" : "2025-05-26 10:46:15", "count" : 1, "pub-type": "inproceedings", "booktitle": "10th European Conference on Synthetic Aperture Radar (EUSAR 2014)","address":"Berlin, Germany", "year": "2014", "url": "", "author": [ "W.

In particular, TSN specifies a time-triggered scheduling mechanism in IEEE Std 802.1Qbv implemented by switches to control when outgoing queues get access to switch ports. Besides this time-triggered scheduling mechanism, other scheduling mechanisms can be active in the network at the same time including priority queuing and a credit-based shaper. Moreover, further supporting mechanisms such as the possibility to interrupt frames already in transmission (frame preemption) are specified by the TSN standards. Overall, this leads to a complex network infrastructure transporting both, real-time and non-real-time traffic in one converged network, making it hard to analyze the behavior of converged networks. To facilitate the analysis of TSN networks, we present TSN-specific extensions to the popular OMNeT++/INET framework for network simulations in this paper including, in particular, the time-triggered scheduling mechanism of IEEE Std 802.1Qbv.

By its very nature, a height field cannot store terrain structures with multiple vertical layers such as overhanging cliffs, caves, or arches. This restriction does not apply to volumetric data structures. However, the workflow of manual modelling and editing of volumetric terrain usually is tedious and very time-consuming. Therefore, we propose to use three-dimensional curve-based primitives to efficiently model prominent, large-scale terrain features. We present a technique for volumetric generation of a complete terrain surface from the sparse input data by means of diffusion-based algorithms. By combining an efficient, feature-based toolset with a volumetric terrain representation, the modelling workflow is accelerated and simplified while retaining the full artistic freedom of volumetric terrains. Feature Curves also contain material information that can be complemented with local details by using per-face texture mapping. All stages of our method are GPU-accelerated using compute shaders to ensure interactive editing of terrain.

Both methods are\n\tcombined in such a way that the mixed-dimension models yield training\n\tdata for the surrogate model, where the surrogate model is parametrisedby\n\tthe degree of narrowing of the peripheral stenosis.
