Q1. What if any data aware functions
do you see need to be supported in the network in the future? Data Transfer
nodes? AI & ML? Privacy functions? How can the network become smart towards
your app's?
For the answer from Olaf Schjelderup,
please watch the Session 2 recording (with the Q&A at the end of the
presentations).
Q2. Do you think that the use of
large amounts of data is financially sustainable in research in the long run?
For the answer from Per Öster, please
watch the Session 2 recording (with the Q&A at the end of the
presentations).
Q3. What is so important with LUMI,
isn’t it just another computer resource?
With the ownership of 10 countries and
the European Commission LUMI is together with the other EuroHPC installations
the first supercomputers and data centers in the world leading class available
for all European researchers. This is a milestone for European research
enabling opportunities for new collaborations in the area of data driven
research. The ambition is that LUMI should have an environment with capacity,
capabilities, software and tools that support all kind of different research
needs. From the beginning the interoperability between the EuroHPC sites, and
eventually national, regional, and local facilities is addressed with the
target to form an eco-system of computing and data resources available for
European research and its global collaborators.
Q4. You say that everything is
becoming "BIG science",
what do you mean with that?
With the term big science, we mean
science executed in large-scale projects, e.g., funded by one or more
governments. Often, the scientists work in multidisciplinary groups spanning
multiple countries, from often more than one continent. Big science involves
very large amounts of data, these days, that need to be gathered, transported,
analyzed, processed, and stored.
Q5. It looks like the length of the Arctic Connect subsea cable system is much greater than crossing the Atlantic. Why do you say it is better latency?
A path across the polar region, drawn
on a Mercator projection of the Earth, shows a length that is greater than in
reality. Round trip time estimations between Stockholm and Seattle show that
using Arctic Connect will be much faster across the Arctic Ocean than through
the North Atlantic Ocean and across the USA.
