Scott Atchley, who co-keynoted #ISC25, posted a really meaningful response to my ISC25 recap blog post on LinkedIn (https://www.linkedin.com/posts/scottatchley_isc25-olcf-frontier-activity-7345786995765395457-lGoq). He specifically offered additional perspective on the 20 MW exascale milestone and the pitfalls of Ozaki. It's short but very valuable context.

First, I was honored that AMD's Mark Papermaster invited me to share some science highlights from OLCF's Frontier. I shared that Frontier has grown slightly in the last year with the integration of the test and development system into the full system. My science highlights included:
• GE Aerospace's efforts to reduce noise generated by their RISE engine that will allow GE Aero to bring it to market sooner,
• NASA's work to understand how to use retro-propulsion to land humans and their gear on Mars,
• Researchers refining the phase diagram for carbon by identifying the narrow region in pressure and temperature that would allow body-centric cubic (BC8) carbon to exist. This material is expected to be 30% harder than diamond, and
• Efforts to understand how drug candidates interact with proteins. Unlike AI efforts such as AlphaFold that approximate protein docking, this effort uses Molecular Dynamics to got the two items close together then it switches to quantum mechanics to get an exact docking. This application actually used over 1 exaflop (1 EF) of full precision (FP64) on Frontier.
I also highlighted what Frontier's replacement, Discovery, will need to support modeling/simulation as well as artificial intelligence. It will need bandwidth everywhere from processors to scale-up bandwidth between processors to scale-out bandwidth across the whole system in addition to lots of high-precision and low-precision FLOPS.
I will reply with more comments. 🧵
