First we looked at the development over time for all of Europe and compared that to the developments world wide. For Europe we look here at all European countries, so not only members of EuroHPC or EU countries.
The total performance of European supercomputers in the TOP500 combined grows steadily from 79 Petaflop/s five years ago until 290 Petaflop/s today. However in percentage of the total world performance, Europe's share decreased from 26% five years ago to 19% today. In total number of systems we also see a decrease from 130 five years ago to less than 100 today.
So, overall the importance of Europe in the TOP500 supercomputing world is slowly declining.
Looking at the figures of EuroHPC countries, the figures are simular - only Russia as European supercomputer country is not involved in EuroHPC.
For EuroHPC countries we included both the current member countries and the observer countries - it is not October yet. It makes sense to look at EuroHPC countries as a unit, as these collectively intend to share financial resources to buy supercomputers and develop the HPC ecosystem. Looking only at EU countries would exclude important supercomputing countries well embedded in the European ecosystem - although we have the numbers for EU only for the past years too. Looking at PRACE countries puts the emphasis too much on the academic usage of supercomputers. And it is EuroHPC that is competing against the other "super powers" US, China, and Japan.
In the past five years there have always been one or two supercomputers located in a EuroHPC country in the TOP10. The share of supercomputers in EuroHPC countries in the TOP100 is slowly declining from 35 five years ago to 30 in the recent list. In the complete list of 500 supercomputers EuroHPC countries' share has declined over 20% in five years to 96 today. Also the share of EuroHPC countries in total installed performance declined over the past five years from 24% to 18 % today.
And what about next year or perhaps 2021? Most likely there will be 3 supercomputers located in EuroHPC countries in the TOP10, but it could be one of them is with national funding (from Germany for instance) and not with EuroHPC funding. Perhaps the decline in the TOP100 will be stopped, but that is very uncertain. With regard to the presence in the overall TOP500 EuroHPC funding will only have a marginal effect on the total number of machines installed. About half of the money that is now put in EuroHPC machines would otherwise most likely also have been invested in HPC systems.
The share of systems in the TOP500 produced with the help of vendors that are from EuroHPC countries is very low, fluctuating between 5% - 7% of the systems installed. Today, 23 out of the 500 supercomputers have involvement from a vendor located in a EuroHPC country.
