<p>The CHTC joined colleagues from 10 countries, representing a range of organizations, spanning from government labs, to universities, to industry. HTCondor technical lead Todd Tannebaum noted that “This [event] is initiated by the European community, it’s driven by the European community, the agendas decided upon by the European community.” And this year, the needs of the European HTCondor user community are growing massively. The <a href="https://ats-news.web.cern.ch/the-long-shutdown-3/">Long Shutdown 3</a> (LS3), the scheduled maintenance for the LHC, is set to begin at the start of 2026 to prepare for “Run 4” or the fourth cycle of the LHC. LS3 will transform the LHC into the High-Luminosity LHC (HL-LHC), creating more particle collisions per second and increasing the amount of data able to be collected. Currently, there are 125,000 running jobs, and Run 4 will require that capacity to run almost 500,000. The <a href="https://indi.to/rS3kn">Can we break HTCondor before HL-LHC Does</a> presentation given by <a href="https://physics.nd.edu/people/antonio-delgado/">Antonio Delgado</a> (University of Notre Dame) and Ben Jones (CERN) concluded that scaling to almost 500k jobs seems possible, a promising sign for the advancement of LHC data collection and processing assisted by HTCondor.</p>

<p><a href="https://www.ppd.stfc.ac.uk/Pages/Chris-Brew.aspx">Dr. Chris Brew</a>, Particle Physicist and Grid Computing Expert at UK Research and Innovation and Organizing Committee Chair, noted that the event is structured to create an environment of community building among HTCondor users and to increase interactions between users and developers. Brew and other organizers have gradually been implementing more “structured open discussion sections,” like the Share your Toolbox Session, to encourage people to stand up and discuss their experience as users. “People enjoy them and lots of people talk and show what they’ve got,” said Brew. The social aspect of the week remained a focus for organizers this year. Brew noted that “Giving people time outside the scheduled sessions just to get together and talk to each other without doing it as a session, it’s very important.” Fairly long breaks are structured into the event which gives attendees time outside of formally scheduled sessions to network in a more casual setting. These coffee breaks are key in building a stronger connection between participants and developers according to Brew: “It’s a lot easier to ask for help from somebody if you’ve had a coffee with them, you’ve chatted to them.”</p>

<p>The tight-knit hands on atmosphere of the European workshops is important to facilitate peer to peer discussion.HTCondor Office hours remained very popular and well attended this year, with two sessions led by CHTC staff Todd Tannenbaum and Greg Thain. <strong></strong>A large part of our research is understanding the real problems that real users have…and we need the inputs of users to understand what their problems are,” noted Thain. Office hours are an opportunity for HTCondor developers to understand the issues of real HTCondor users, which is important for internationally shared resources, like the LHC, which depend on international collaboration in science.</p>

<p>An exciting development coming out of this year’s workshops is that CHTC will now be hosting virtual office hours, open to European or American users starting in 2026. Rather than solely serving as an opportunity for users to talk to HTCondor experts about HTCondor, these office hours will also serve as an information sharing network between HTCondor users across the globe, facilitating peer to peer discussion and allowing for faster, more efficient streams of information.</p>
