  • The CAMINOS interconnection networks simulator
    Cristóbal Camarero, Daniel Postigo, Pablo Fuentes
    Journal of Parallel and Distributed Computing, 2025
    This work presents CAMINOS, a new interconnection network simulator focusing on router microarchitecture. It was developed in Rust, a novel programming language with a syntax similar to C/C++ and strong memory protection. The architecture of CAMINOS emphasizes the composition of components. This allows new designs to be defined in a configuration file without modifying source code, greatly reducing effort and time. In addition to simulation functionality, CAMINOS assists in managing a collection of simulations as an experiment. This includes integration with SLURM to support executing batches of simulations and generating PDFs with results and diagnostics. We show that CAMINOS makes good use of computing resources. Its memory usage is dominated by in-flight messages, showing low overhead in memory usage. We attest that CAMINOS can effectively use CPU time, as scenarios with little contention execute faster.
  • Defining the Boundaries for Endpoint Congestion Management in Networks for High-Performance Computing
    Daniel Postigo, David Herreros, Eloy Barón, Cristóbal Camarero, Pablo Fuentes
    Snta 2024 Proceedings of the 2024 7th International Workshop on Systems and Network Telemetry and Analytics Part of Hpdc 2024 33rd International Symposium on High Performance Parallel and Distributed Computing, 2024
    A hotspot traffic pattern of communications can be a common phenomenon in HPC topologies that causes significant and lasting network performance degradation. This performance deterioration remains persistent over time, intensifying its impact even after the cessation of the detrimental traffic injection into the network. To understand its causes and effects, we analyze the network behavior under different hotspot traffic scenarios and compare the performance on various topologies. We examine both the performance drop due to traffic flows with endpoint contention, and the recovery process of the network after this phenomenon has occurred, if swift action is taken to mitigate it.
  • Leveraging a visual language for the awareness-based design of interaction requirements in digital twins
    Rafael Duque, Crescencio Bravo, Santos Bringas, Daniel Postigo
    Future Generation Computer Systems, 2024
    User interfaces for digital twins (DTs) should provide information that allows the user to be aware of the state of the physical entity that is virtualised. Typically, this real entity is a shared space in which various human and artificial agents interact (for instance, in smart cities, various citizens and vehicles interact; in manufacturing, operators and machinery cooperate in the production, etc.) and the user interface must provide information about its state. This work presents ADD (Awareness Description Diagrams) as a technique for modelling requirements of Human-DT interaction. A study was conducted in order to virtualise a natural space where groups of hikers carry out their activities. This study assesses the learning curve of ADD, its feasibility to model Human-DT requirements, and its utility to design user interfaces. The results of the study provide valuable insights into the effectiveness of the ADD technique.
