    Networking & Security

    The Port d’Informació Científica (PIC) serves as a critical data and computing hub for numerous scientific experiments, with the vast majority of its resources dedicated to the Worldwide LHC Computing Grid (WLCG). While standard LHC grid operations rely heavily on traditional batch submissions, the growing demand for interactive, Tier-3 analysis facilities requires a shift toward scalable,...

  2. 17. HEPiX IPv6 Working Group Update
    David Kelsey (Science and Technology Facilities Council STFC (GB))

    Networking & Security

    The HEPiX IPv6 Working Group has been encouraging the deployment and use of IPv6 in WLCG for many years. At the last HEPiX meeting in China we reported that more than 70% of all WLCG sites have worker nodes and compute services that are IPv6-capable. That campaign continues. We also presented news that the USA Tier1 sites had successfully removed IPv4 peering from their LHCOPN connections. We...

  4. 32. A phased phase-out plan for IPv4 at a WLCG Tier-1 site
    Mattias Wadenstein (University of Umeå (SE))

    Networking & Security

    Universities and research institutes have been early adopters of IPv4, which
    have served scientific research infrastructure well in the past. But now the
    time has come to let go of the legacy protocol with awkward limits, and phase
    it out in favour of IPv6.

    The World-wide LHC Computing Grid (WLCG) is half-way through the transition
    from IPv4 to IPv6, with almost all services now being...

  5. 38. CZ-Tier-2 Network Tests
    Jiri Chudoba (Czech Academy of Sciences (CZ))
    23/04/2026, 16:00
    Networking & Security

    The Czech WLCG Tier-2 consistently meets its computing and storage commitments to the LHC experiments through a geographically distributed infrastructure. CZ-Tier-2 resources are spread across three sites, connected by high-bandwidth links operated by the Czech NREN, CESNET. Additionally, substantial CPU resources from the Czech national supercomputing center IT4I are incorporated into WLCG...

  6. 71. Worldwide Computer Security Situation
    Dawid Kulikowski
    23/04/2026, 16:20
    Networking & Security

    This presentation aims to give an update on the global security landscape from the past year. The global political situation has introduced a novel challenge for security teams everywhere. What’s more, the worrying trend of data leaks, password dumps, ransomware attacks and new security vulnerabilities does not seem to slow down. We present some interesting cases that CERN and the wider HEP...
