One of the highlights was the opening key note "The Exascale Challenge and its Impact on All of Us" by Erwin Laure Professor in Computer Science and Director of PDC at the Royal Institute of Technology (KTH) in Stockholm, Sweden. He explained what is needed to get, eventually, to exascale supercomputers, and what work is done. Key for the development are European research projects. He explained some work done in older projects, like EPiGRAM and new ones that are about to be started like Intertwine.

How much traffic is going over the Internet? Actually nobody knows exactly. Micael Engström from Arbour Networks says his company is monitoring 120 Tbps of Internet traffic 24/7. They estimate it is about 1/2 of all traffic. Goal of this monitoring is to identify Denial of Service (DoS) attacks or other attacks to systems. Attacks can be very large. The biggest one last year was 400 Gbps.
Engström explained how the Internet is monitored - there is a nice interactive tool publicly available - and what can be done to prevent attacks, and how to deal with attacks. If you are under attack, perhaps the most important advice is: "do not panic". Do not shutdown or reboot your firewall as this could open up doors for attackers to get in.

HPC can be big, but you cannot reach exascale if you do not have a complete HPC pyramid that has a base of hundreds of clusters at universities and research centres.
Lauris Cikovskis, researcher at the Riga Technical University and Ilmārs Slaidiņ , Co-Chair of e-IRG Executive Board 2015, Riga Technical University presented the e-Infrastructure for Science set-up at their university. The RTU HPC centre started 2 years ago. Most recent developments are the building of a new small data centre with 200KW IT power.

Open Science and innovation need education. Anders Flodström, EIT ICT Labs, gave two presentations on this topic. One at the e-IRG workshop - Open Innovation and Open Science - Brainchildren - and the other one at the HPC day - Innovation and jobs in the Digital Era, the role of education. According to Flodström, the most important is societal infrastructure.

But all those infrastructures - HPC, networking, IT education - should eventually lead to useful applications. One of those - modelling of the heart on parallel systems - was presented by Andre Sozykin of the Ural university. The LeVen system simulates the heart left ventricle. Both mechanical and electrophysiological properties are simulated. Parallelisation was done in OpenMP for parallel SMP machines. Speed-up was 6. But scalability is limited, so other ways need to be explored.
