US supers maintain grip on Top500 list as China seemingly hides its powers

American supercomputers continued to dominate the Top500 ranking of the world's mightiest publicly known silicon machines this northern spring, with Oak Ridge National Laboratory's Frontier still the only exascale system on the list. But while US and European supers held their positions as they prepare to unleash new exascale …

UK?

I know this list is to some extent willy waving, but why is the UK so under-represented in the list?

Re: UK?

Maybe because the UK is broke and can't afford these high end tools?

"Liz Truss’s disastrous mini-budget cost the country a staggering £30bn – doubling the sum that the Treasury says will have to be raised by Jeremy Hunt this week in a huge programme of tax rises and spending cuts.

The independent Resolution Foundation calculates that the Truss government was responsible for about £30bn of the fiscal hole which the Treasury puts at £60bn, and which Hunt will have to tackle in the autumn statement on Thursday."

Re: UK?

The government has launched a great Patriotic effort to scour the nations attics and car boot sales for old Speccies and BBC micros which will be put in a shed somewhere and form the UK's supercomputer center

Top500 and Linpack are Technoporn

If only all applications only ran Linpack and nothing else. A colleague decades ago stated 'I can vectorise to 99.5% and I can parallelise to 99.5% but I cannot do both at the same time'. Make systems dependent on GPUs and voila, it is a 'poor man's parallel vector system'. Software matters more than hardware and scalability makes for a fascinating problem including the necessity of redundant computations burning FLOPS and watts, keeping it over simplified.
