Digitaaliset kaksoset Tieteiden yössä

Digitaalinen kaksonen on fyysisestä tutkimuskohteesta tehty digitaalinen kopio, jossa yhdistyvät mallinnus ja havaintodata. Esittelimme Tieteiden yön verkkotapahtumassa CSC:llä kehitettävät digitaaliset kaksoset: ilmastokaksosen ja biodiversiteetin digitaaliset kaksoset.

Global advantage through high-performance quantum computing

Quantum computers have the potential to provide a game-changing boost for science. For maximum benefit to society, quantum computers will need to merge with traditional high-performance computing. Here, international collaboration is of key importance for bringing the required expertise and know-how together.

Molecular Dynamics, the most used method in CSC's environment

Molecular dynamics is one of the most used simulation techniques on CSC supercomputers. Typically, each atom is modelled separately to build molecules or materials – the physical system that the researcher is interested in – and then physics is set in motion to see what happens.

How did LUMI end up in Finland?

LUMI supercomputer’s second installation phase is currently ongoing at CSC’s data center in Kajaani, Finland. Soon researchers across academia and industry will have an unforeseen tool – Europe’s fastest supercomputer. Getting the LUMI supercomputer to Finland was no forgone conclusion. Although the LUMI consortium, led by CSC, officially joined the competition to get one of the three EuroHPC pre-exascale supercomputers to Kajaani in 2019, the background work began years earlier.

At the racing track of quantum computers

In a sense, quantum computers are already much more powerful than traditional supercomputers. In the form of the ever-useful car analogy: quantum computers of today are like the fastest racing cars ever built, or even imagined. There is a caveat, however.

Open course on supercomputers

Major scientific, technological and industrial breakthroughs require increasingly sophisticated and advanced tools. One of the most important research tools today is a supercomputer. In order to raise awareness of supercomputers and the benefits of high-performance computing, CSC and Kajaani University of Applied Sciences jointly created an open online course called Elements of Supercomputing.

Älkäämme jättäkö jo tehtyjä TKI-investointeja hyödyntämättä!

Mediassa on viime aikoina kirjoitettu CSC:n Kajaanin datakeskukseen sijoitetusta LUMI-supertietokoneesta, mm. Helsingin Sanomat kirjoitti lokakuussa otsikolla ”Euroopan nopein tietokone ratkoo pian suuria pulmia”. Kirjoitus kiteytti hyvin LUMIn käyttötarkoituksen eli eurooppalaisten tutkijoiden löytämien ongelmien ratkaisun – nopeasti. Huomionarvioista on, että hyöty on suuri koko Euroopalle, mutta myös Suomelle itselleen.

The housing market’s quantum future

Quantum computers are hitting the world with a bang. Qubits, the turbo-charged quantum cousins of regular bits, are revolutionising computational research and modelling, including and especially in the financial sector.

Emulated quantum noise

In the future, quantum computing can solve certain tasks more efficiently than traditional computers; some problems are so complex that supercomputers in their classical form will never figure them out. This requires quantum computers that are considerably more powerful than current devices, however. The power of a quantum computer depends on both the number of qubits and their quality. Quality can be studied using CSC's quantum computer emulator Kvasi.

E-TASC Hel: like taking part in an apocalyptic sci-fi movie

EuroFusion E-Tasc Hel is an EU-funded project to improve and unify numerical tools for supporting the construction of fusion reactors. We have to model the dynamics of ITER and DEMO to the best of our ability in order to give the reactors the best possible chance of being functional. When I indicate that a lot of mankinds future depend on projects like this, I am not exaggerating that much.

To all young climate activists claiming we leave it all to them – Sorry, I beg to differ

Young climate activist – your task may well be to protest and demand changes and actions, but to claim that we in the older generations are not really contributing and that we leave the entire burden on you - Sorry, I beg to differ.

At the start of a quantum leap

Quantum computers are a focus of attention right now, and for good reason: now we know that they work! It has been said that quantum computers have now evolved from a physicist’s dream to an engineer's nightmare.

Suurtehokvanttilaskenta – lähentymistä luvassa

Kvanttilaskenta on tulevaisuuden HPC-ekosysteemien kulmakivi. LUMI-supertietokone yhdistää HPC-asiantuntemusta poikkeuksellisella tavalla, joten on korkea aika tehdä sama myös eurooppalaisen kvanttiosaamisen alalla.

Combined machine learning framework for supercomputing. Blog post 2/3

What would a combined machine learning framework look like and which primary components it requires? From the technical point-of-view, it makes most sense to have the interactive part running on Kubernetes, while the batch jobs would run in the HPC cluster.

Modern machine learning with supercomputers. Blog post 1/3

What does it take to provide the most powerful AI system possible? For us working in supercomputing centres around the world, “most powerful” is where we are aiming at all the time. After all, pushing the limits of computing is what we are paid to do.
