Conclusion: Computation as a Catalyst for Discovery

The scientific stories that emerged from CLAIX-2018 in 2019 reveal a fundamental truth about modern research: computational modeling has become as essential to scientific progress as traditional laboratory work. From understanding the intricate dance of atoms in a receptor protein to designing novel materials atom-by-atom, high-performance computing enables us to explore domains that are inaccessible through experimentation alone.

The CLAIX-2018 project demonstrated that Germany could not only compete but excel in the global high-performance computing landscape, achieving recognition for both raw computational power and energy-efficient operation. As we face increasingly complex global challenges—from developing targeted therapeutics to designing sustainable materials—the computational capabilities pioneered by systems like CLAIX will prove indispensable in our quest for knowledge and innovation.

The legacy of CLAIX-2018 continues to influence the direction of high-performance computing, reminding us that behind the impressive rankings and technical specifications, the true measure of a supercomputer's value lies in the scientific discoveries it enables and the boundaries of knowledge it helps expand.
