  - AlmaLinux and Nvidia 5m
    
    Speaker: Alex Iribarren (CERN)
    
    AlmaLinux is not officially supported by Nvidia. In order for it to become a supported platform, there should be pressure from user communities, like WLCG. We would like the MB to consider sending an email to Nvidia on behalf of WLCG. A possible text might be:
    
    To whom it may concern:
    
    The Worldwide LHC Computing Grid (WLCG) Collaboration provides the infrastructure that supports the computing needs of the CERN experiments at the Large Hadron Collider. This infrastructure spans approximately 150 data centers across more than 40 countries, offering over one million CPU cores and 3 exabytes of storage.
    
    There is a rapid growth in demand for GPU capacity in WLCG and particularly NVIDIA GPUs. Many data centers in WLCG use AlmaLinux as the distribution for the operating system. In this context, official support for AlmaLinux from NVIDIA would significantly ease integration and deployment of GPU resources, helping us to scale efficiently and reliably.
    
    We kindly urge NVIDIA to consider adding AlmaLinux as a supported platform in your software stack. Such support would be of great value to the global scientific computing community.
    
    Best Regards

  TCB Report 10m
  
  Speakers: Alessandro Di Girolamo (CERN), James Letts (Univ. of California San Diego (US))
  
  A meeting of the TCB took place on Thursday, July 2nd [1], where “facilitators” were matched with several of the chapters of the WLCG Technical Roadmap (TR) document. Follow up emails went out last week on the next steps with the TR, as well as following up with OTF#5 [2] on resource provisioning with k8s. The next TCB meeting has been scheduled for Thursday, August 28th at 15:00 (CERN) [3].
  
  Planning for OTF#6 [4] in September and OTF#7 [5] co-hosted with the FTS & XRootD workshop at PIC in October is underway. OTF#8 originally planned for late November or early December could be merged into the December WLCG Workshop at CERN.
