National Exascale Day
National Exascale Day celebrates a computing milestone: systems that can handle a quintillion calculations each second. These machines, called exascale supercomputers, bring enormous power to scientific research.
Position your organization as a forward-thinking innovator by sponsoring or participating in exascale computing education and awareness—targeting tech professionals, researchers, and enterprise decision-makers.

National Exascale Day began in 2019, created by Cray (now part of Hewlett-Packard Enterprise) and the U.S. Department of Energy. Several national labs joined in, including Oak Ridge, Argonne, and Lawrence Livermore.
The purpose was simple: celebrate the people behind one of the biggest leaps in computing—exascale performance. That means machines able to do a billion billion calculations every second.
The day was set for October 18 because 10/18 represents the number 10¹⁸, the heart of exascale computing. On the first celebration, the labs hosted events and talks to share how these powerful systems would help solve real-world problems.
They focused on science, energy, health, and national security. The Exascale Computing Project, run by the Department of Energy, helped lead the effort.
Since then, the day has grown. Each year, it shines a light on new milestones like Frontier, Aurora, and El Capitan—some of the most powerful supercomputers in the world.
Researchers use these systems to study climate change, design new drugs, and improve clean energy solutions.
National Exascale Day honors their work and the technology behind it. It’s a chance to recognize the power of science, teamwork, and big ideas turned into reality.
Host a mini learning session
Gather friends or family for a short talk about exascale computing’s real-world uses. Keep it lively and interactive. Use clear visuals or simple analogies to make the topic click.
Watch expert talks online
Search for panel sessions or recorded webinars featuring scientists or engineers sharing exascale breakthroughs. HPE and DOE releases often feature lively discussions. Briefly summarize key takeaways afterward.
Share a themed post
Write a short social media note about how exascale tech helps medicine, climate science, or AI. Add a fun quiz—ask followers what “exa” means—to spark engagement.
Create a hands-on demo
Show how fast your computer or phone can do calculations compared to exascale scales. Use a stopwatch or simple code. It’s a low-barrier way to feel the contrast.
Invite an expert Q&A
Reach out to someone who works in science or tech. Let them explain why exascale matters. A 15-minute chat or live session can bring powerful insight to your circle.
Read a spotlight article
Find a short article or blog about recent exascale milestones like Frontier, Aurora, or El Capitan. Pick one highlight and tell someone what strikes you most.
Draw or sketch the concept
Encourage kids (or yourself!) to draw what a quintillion calculations might feel like. A visual makes the big number feel less abstract and more fun.
