A Record-Breaking Confluence of Innovation, Inspiration, and Inclusivity


This year’s gathering of the brightest minds and leading technologies in high performance computing (HPC) met in Denver for SC23, marking the 35th anniversary of the International Conference for High Performance Computing, Networking, Storage, and Analysis. If you missed the anniversary exhibit, not to worry. You can still celebrate with us by visiting the 35 Years of SC page.


14,295 Attendees

438 Exhibitors

Notably, this year drew a record-breaking 14,295 attendees, reflecting the world’s ever-expanding interest in HPC. The exhibit floor was also packed with 438 exhibitors, also an SC record, of which 90 were entirely new to the conference.

This convergence of all things computing was exemplified by the SC23 theme, “I Am HPC,” which served to remind everyone that they are an equal and welcome contributor to this thriving HPC community. As the SC23 General Chair, Dorian Arnold put it, the theme “aims to humanize the field of High Performance Computing and ensure it’s accessible to all.”

Speaker Highlights 

Covering Important Topics in HPC

The speakers and the diverse areas they represent are among the primary draws for attendees. SC23 presented exciting orators who helped personalize the experience of working in HPC.


An Inspirational Keynote

Hakeem Oluseyi’s keynote speech was especially relevant to this year’s theme of “I Am HPC.” Oluseyi’s life story provided a shining example of how intelligence and hard work can overcome adversity. Moreover, Oluseyi posed the notion that while receiving resources necessary to succeed can be needlessly difficult for so many people, it often only takes one outstretched hand to make a difference.

Opening Plenary Brilliance

The opening plenary panel was hosted by Valerie Taylor of Argonne National Laboratory. Taylor moderated a discussion, I Am HPC: The Impact and Future Directions of HPC, featuring Kathy Yelick of the University of California Berkeley, Mateo Valero of the Barcelona Supercomputing Center, Enobong (Anna) Branch of Rutgers University, and Frank Indiviglio of the National Oceanic and Atmospheric Administration.

While technology was up for discussion, the group also addressed issues concerning the STEM pipeline and its reach within underrepresented sectors of society and the daily impacts HPC has, including in areas such as biomedicine and drug design, threat assessment, and climate modeling.

SCinet Delivers

Empowering Research & Discovery at SC

When a big group of HPC experts get together, their intense computing needs generally outpace what an average conference would require.


WHen Powerful Matters

SCinet is created annually for use by exhibitors and attendees at the SC conference. Since this network must be able to perform extraordinary feats, such as the 400G connectivity required by AmLight for a research experiment, SCinet is the fastest network in the world for the week of the SC conference.

SCinet by the numbers

This year, SCinet required 66,814 feet of fiber optic cable, around two times Mount Everest’s height. The network was capable of 6.71 terabits per second, allowing someone to download Netflix’s entire content library in about an hour. Every piece of equipment in the network is donated, and this year’s total retail price for the donated equipment used to drive SC23 was approximately $40 million.

Awards Spotlight

Congratulations to All the Awardees

The SC Conference recognized professional achievements throughout the HPC community.

Onward to the Next SC


SC24 in Atlanta, GA

As always, Denver was a gracious and hospitable host for SC23, thanks partly to the excellent infrastructure provided by the Colorado Convention Center in Denver. Next year, SC24 will take place in Atlanta at the Georgia World Conference Center. The SC24 conference theme is “HPC Creates” and will focus on the enormous generative power that supercomputing affords the modern world.


Early SC24 Applications

Presently, Women in IT Networking at SC (WINS) is seeking qualified female candidates in their early- to mid-career to join the SCinet volunteer workforce at SC24. WINS is heavily focused on diverse representation and will provide full travel support and mentoring by experienced engineering experts before, during, and after the conference.

Additionally, Lead Student Volunteer applications have opened. This is a fantastic opportunity for former student volunteers interested in elevating their SC experience.
