  • Extending LinkTest for BXI interconnects
    Authors: Yannik Müller, Ilya Zhukov and Vitor Silva (Jülich Supercomputing Centre, Forschungszentrum Jülich, Jülich, Germany) I. Introduction Efficient communication among processes is vital in the High-Performance Computing (HPC) world. To gain insights into the current network’s state and identify potential bottlenecks, a reliable network benchmarking tool is required. This is … Read more
  • COSSIM framework
    An Open-Source Integrated Solution to Address the Simulator Gap for Parallel Heterogeneous Systems Authors: Nikolaos Tampouratzis (EXAPSYS), Yannis Papaefstathiou (EXAPSYS). Nowadays, highly parallel and distributed computing systems (i.e., Cloud and HPC systems) are growing in capability at an extraordinary rate, incorporating processing systems that vary from simple microcontrollers to high … Read more
  • The VEF Traces framework
    A set of tools to reproduce communication traffic of parallel applications in high-performance interconnection network Simulators Authors: Miguel Sánchez de la Rosa (UCLM), Gabriel Gómez López (UCLM), Francisco J. Andújar (UVA), Jesús Escudero Sahuquillo (UCLM), Pedro J. García (UCLM), Francisco J. Alfaro (UCLM), Francisco J. Quiles (UCLM) and Jose L. … Read more
  • Extending ParaStation MPI by BXI Support
    Authors: Simon Pickartz (ParTec), Carsten Clauss (ParTec) The ParaStation MPI communication stack is a central pillar of ParaStation Modulo. This is a comprehensive software suite especially designed for systems following the design principles of the Modular Supercomputing Architecture (MSA). It is the selected middleware powering the DEEP projects but is … Read more
  • Development of multirail feature in MPC for BXI interconnect
    Authors: Gilles Moreau (CEA), Hugo Taboada (CEA), Marc Pérache (CEA) 1  Introduction Context Nowadays, HPC applications scale to several hundred nodes, and MPI has become the de facto standard for internode communication. It abstracts Point-to-Point (P2P) communication to the application developer while taking advantage of the underlying network. With ever … Read more
  • A peek at BXI V2 performance
    Editor: Fabien Locussol, Interconnect & Network Product Manager at Atos RED-SEA builds upon the European interconnect BXI (Bull eXascale Interconnect) from Atos. BXI is already in production and featured in Top 500 systems. RED-SEA aims to enhance and extend it to meet the challenges of the Exascale era. This page … Read more
  • Application-defined, high-performance packet processing with sPIN
    Salvatore Di Girolamo, ETH Zürich Need for network acceleration Datacenter and HPC systems are growing at unprecedented speeds. The Frontier supercomputer has been recently deployed at the Oak Ridge National Laboratory in Oak Ridge, Tenn, making it the first exascale system in the United States. At their core, these systems … Read more
