Default Oakridge National Labs "Summit" Super Computer Analyzes Covid 19

The findings are very interesting.

"The computer had revealed a new theory about how Covid-19 impacts the body: the bradykinin hypothesis. The hypothesis provides a model that explains many aspects of Covid-19, including some of its most bizarre symptoms"

The 2nd fastest computer in the world. The labratory would be quite selective in who gets to enter data.

What I find most interesting about this is that I worked on the design and did the reliability study at ORNL for the chiller plant that cools this computer and it’s actually working. Unreal.

All kidding aside, the underfloor piping was so large that when you popped a floor tile, you needed a ladder to get down into the underfloor space. Each processor bank was cooled with an open spray refrigerant system and chilled water piping was routed through each cabinet. There were a ton of cabinets and this machine had 35,000 parallel processors. The previous Cray Jaguar had 228,000 parallel processors. Amazing technology.

How many tons of cooling capacity? And I would imagine all redundant?

18,000 tons as I recall. Full redundancy for all systems including chillers, pumps, towers, etc. Only single points of failure I can recall from the reliability analysis were in the controls and piping systems. Also worked on implementing water side economizers to save some energy when conditions were right.

Get your sunshine or take vitamin D daily! Hopefully this will lead to more effective treatment of those infected.
