High-Performance Computing (HPC) is the application of “supercomputers” to computational problems that are either too large for standard computers or would take too long to solve. HPC is a pervasive tool for both academia and industry. “Today, to Out-Compute is to Out-Compete” best describes the role of HPC.

A recent seminar brought together HPC users, administrators and visionaries. Researchers talked about their experiences with using HPC in their daily work. The administrator of Tartu HPC center introduced the backstage of managing large amounts of data. Finally, we took a closer look at the new supercomputer LUMI, which will launch in 2021, to take computing performance to a new unprecedented level.
