Students from USI and ETH Zurich visiting CSCS
Prof. Olaf Schenk and the Institute of Computing (CI) had the pleasure of inviting a group of 80 bachelor's and master's students from USI and ETH Zurich to visit the Swiss National Supercomputing Center in Lugano-Cornaredo on 12 October.
The students were welcomed by Dr Maria Grazia Giuffreda, associate director, who gave a presentation of the centre prior to the visit. She gave an overview of some of the 153 projects carried out last year with the help of the CSCS supercomputers.
After this introduction, Sebin John, a master's student in software and data engineering at USI, filled the audience with his enthusiasm and shared his experience as a research intern at CSCS where he developed distributed visualization software in Julia. The students were all ears when Timothy Holt, PhD candidate in high-performance computing, gave a speech on how supercomputing can help with the European energy crisis.
The group was then led into the spacious computer centre facility where they were able to approach supercomputers such as Piz Daint, once the most powerful machine in Europe, or the ultramodern Alps. The participants also gained insight into the impressive technical infrastructure essential for water-cooling the supercomputers. The many questions and discussions between the participants and the staff continued over coffee in a relaxed atmosphere.
CI Researcher shows how mathematics can help AI in biomedicine
At the USI Institute of Computing (Faculty of Informatics), Prof. Illia Horenko has devised a robust unified model learning strategy based on new and very efficient solutions to traditional mathematical and statistical problems, opening to significant developments in fields such as healthcare. His work is published in PNAS, the official journal of the National Academy of Sciences.
The idea behind the computational strategy proposed by Prof. Horenko, called Entropic Outlier Sparsification (EOS), is to improve learning from data and the accuracy of predictions when in presence of data anomalies and outliers by exploiting the potential of novel math-driven learning and mathematical methods. A field with huge potential for adopting this sort of strategy is that of biomedicine and healthcare. For instance, large yet unraveled potential of such methods is in improving diagnostics of cardiovascular diseases.

Here in Ticino - the European HPC master's program will develop new experts equipped for the supercomputing revolution, writes Ticino Scienza
USI, together with ETH Zurich, The Swiss National Super Computing Center (CSCS), and 6 other European universities, will launch the new European HPC master's program supported by EuroHPC in 2022. This cutting edge master's program was recently featured in an article in Ticino Scienza. The article explains how this new partnership will help develop world class talent in the critical areas of high-performance computing and computational science, which will be key drivers in the European digital transformation. Aside from being strategically important for Switzerland and particularly Ticino, the article cites, this new sector is rapidly expanding, and could potentially draw additional high-value economic activity to the region.
USI joins the first European Master's programme in HPC
A consortium of European partners led by the University of Luxembourg has been selected by the EuroHPC Joint Undertaking to design and implement the first pan-European High-Performance Computing (HPC) pilot Master’s programme. Università della Svizzera italiana is a member of the consortium that will offer courses from Autumn 2022 to provide students with outstanding career perspectives in the rapidly expanding field of HPC, High-Performance Data Analytics (HPDA), or Artificial Intelligence.
Olaf Schenk, Professor of Computer Science at the USI Institute of Computing comments: "This initiative will be integrated into the Master of Computational Science (MCS) at USI. Our graduate students will be fully supported by the project in terms of living costs, tuition fees, mobility costs, industrial internships, etc. It will give our MCS students access to a European network of leading universities active in the area of computing and data science. We will also receive funding for our CSCS-USI summer school, which this year had over 120 participants (students from USI, ETHZ, EPFL). The EU project also supports the creation of teaching material for High Performance Computing and Data Analytics courses". The EU-funded initiative is supported at USI by the Institute of Computing (CI) and the Computer Systems Institute (SYS) at the Faculty of Informatics. ETH Zurich and the Swiss National Supercomputing Centre (CSCS) are participating in the project as contributing university/center. ETHZ will also integrate some of the USI teaching courses within the ETH Master of Computational Science and Engineering.
With a total budget of 7 million euros, the consortium of European universities, research/supercomputing centres, and industrial partners will develop a higher education programme with the main objectives to (1) train students in areas such as the design, deployment, operation, and/or the use of current and future generation HPC and HPC-related technologies in Europe; and (2) to train experts skilled in driving HPC adoption and knowledge transfer in industry and academia in different strategic domains, thereby linking HPC activities in industry and academia.
While many university curricula include basic computer science and programming languages, education programmes today must be adapted to a rapidly developing HPC technology ecosystem. The curriculum of the HPC pilot Master’s programme will be designed in a modular structure to enable full or partial integration of the modules into new or existing Master’s programmes. The availability of HPC proficient data scientists, HPC application developers, and expert users, is a key factor that drives digital transformation in Europe and requires the training of highly skilled and talented graduate students.
The consortium led by the University of Luxembourg consists of universities, research/supercomputing centres, industrial and SME partners, and additional supporting partners. Eight universities will initially be awarding degrees: University of Luxembourg, Universitat Politècnica de Catalunya, Politecnico di Milano, Friedrich-Alexander-Universität Erlangen-Nürnberg, Sorbonne Université, Sofia University St. Kliment Ohridski, Università della Svizzera italiana, Kungliga Tekniska Hoegskolan). It was selected following the call for proposals EuroHPC-2020-03 "Training and Education on HPC", which was launched in March 2021, as the last R&I call of the EuroHPC JU within the 2014-2020 Multiannual Financial Framework.

The 2021/22 USI-FAU double degree program in Computational Science has kicked off!
At the end of September a delegation of faculty members and students from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) visited Lugano to celebrate the launch of the Double Degree Program in Computational Science and Computational Engineering between USI and FAU for the academic year 2021/22. This is the second year that the Double Degree Program is organised at USI.
The itinerary included a tour of the facilities available to students on the new USI East Campus, as well as a visit to Lugano and Gandria, and a hike up the Monte Bré. The visit concluded with a welcome event where students had the opportunity to meet each other, learn more about the double degree program, and each of the host universities.
The USI-FAU Double Degree Program offers participating students the opportunity to study in two world-class research institutions in the field of informatics and engineering, and live and experience the culture in two diverse regions of Europe. After three semesters of course work (2 at the host university, 1 at the partner university) and a Master’s thesis, the students are awarded a Master’s degree from each university. This year, there are 27 students enrolled in the double degree program and it is expected this to keep growing in the coming years as the word spreads.
Michael Zideki from Erlangen was very enthusiastic about his double degree, saying it is "a unique opportunity to get different perspectives on your studies". Adding to that, one of this year's Master in Computational Science students at USI, Nicola Esposito, says, "the double degree fully meets my expectations. Together with the FAU classmates we also had a great kick-off gathering and enjoyed meeting other students of this program, which was refreshing and useful!".
