Re: How much supercomputer does £330m buy?
You can see some of the research that has been enabled by the current machine (Archer2) at https://www.archer2.ac.uk/research/case-studies/
It all looks important and beneficial to me.
If we are serious about retaining and attracting scientists to the UK, we need to ensure that the resources they need are available, and a serious HPC machine is such a resource.
This is not a hype-laden AI machine, but one for running important scientific codes to enable research. (Many of which may even be in Fortran :-) https://cpufun.substack.com/p/is-fortran-a-dead-language)
