Summary
The UK’s national supercomputer, Archer2, has fallen to 62nd place globally, leading to concerns about the country’s supercomputing investment.

Current modern supercomputers are actually a mesh of relatively lower spec machines, not a single “computer”, per se. The cost of these isn’t the hardware, it’s the low-latency interconnects and writing the software that can carry out jobs in a massively parallel way.

My question is “what is the purpose of a single cluster like this?”.
