You may not consider it large-scale, but we wanted to have two RISC-V servers for teaching (in particular, for the compiler course). Some years earlier we had written that into a "future plans" document, and in 2022 we got the request to buy them now, because the period that was covered in that document was coming to an end. Of course at the time the best RISC-V thing to be had was the Visionfive V1, which was cheap, but too weak for our purposes (cross-compiling would have been possible, but we did not want to go there). So we eventually settled on two servers based on the Rocket Lake, which at least gave us AVX-512 (the deadline was too early for Zen4). Now it's two years later, and the RISC-V servers are still not showing up. We'll see how things look when it's time to retire the Rocket Lakes (their predecessors were good for a decade). - anton -- 'Anyone trying for "industrial quality" ISA should avoid undefined behavior.'
