Alan Sill @alansill.mast.hpc.social.ap.brid.gy · 08/08/2026This is, of course, totally unacceptable. But it’s the natural consequence of Republicans giving this rogue agency hundreds of billions of dollars with no oversight or accountability. 001 1
Alan Sill @alansill.mast.hpc.social.ap.brid.gy · 29/07/2026This is brilliant!

Alan Sill @alansill.mast.hpc.social.ap.brid.gy · 23/11/2025I really enjoyed my time at #SC25. Thanks to everyone who stopped me in the halls, took time to talk with me about things you thought were important, or stopped by to visit us at the Texas Tech booth. It was a really enjoyable experience. Thank you! 000 0

Alan Sill @alansill.mast.hpc.social.ap.brid.gy · 20/11/2025A highlight of the #SC25 exhibit for me was explaining our x86-based small-scale #HPC mini-clusters that run a full true software stack to a living legend, Jack Dongarra. These were used to prepare postdocs and students to run the much larger cluster for the NSF ACCESS repacss.org project. 152 5
Alan Sill @alansill.mast.hpc.social.ap.brid.gy · 18/11/2025Made my day when @geerlingguy stopped by the Texas Tech #SC25 booth to take a look at our x86 mini-clusters that run Warewulf, Ansible, Spack, and complete scientific #HPC applications with the same software stack as on our main clusters. 111 1
