UK's Arm-based Isambard 2 supercomputer powers off for good
Briefly

"Isambard 3 takes over today using Nvidia Grace Arm-based CPUs provided by HPE." This statement indicates a significant upgrade in processing capability as Isambard 2 ends its service, marking the transition to a more advanced supercomputing resource.
"Isambard 3 early access use began last week and will ramp up over the coming months. Once the system has operated successfully for a few months, we'll pass acceptance and go into full production use." This insight sheds light on the gradual phase-in of the new system, ensuring it meets operational standards before full deployment.
"The 640M core hours impressed me for a modestly sized machine!" This reflects the efficiency and utilization of Isambard 2, demonstrating its significant impact despite being a relatively smaller supercomputer.
"based on the success of that system, the GW4 Alliance was able to secure funding from the Engineering and Physical Sciences Research Council (EPSRC) in February 2020 to create Isambard 2." This highlights the foundational role of Isambard 1 in attracting further funding and advancing high-performance computing in the UK.
