Just asked Claude 3.5 Sonnet a question about supercomputers and got this as the answer:
Let me help break down this supercomputer in more understandable terms.
El Capitan is currently the world's fastest supercomputer, and here's what makes it special in simpler terms:
Processing Power: It has over 11 million cores (11,039,616 to be exact). To put this in perspective, a typical high-end desktop computer has 8-16 cores. So this is like having about 690,000 high-end desktop computers working together!
Power Consumption: It uses about 29.6 megawatts of power (29,580.98 kW), which is enough to power roughly 24,650 average American homes.
Performance: The computer's performance is measured in "PFlop/s" (Petaflops), which means quadrillions of calculations per second:
- Its measured performance (Linpack) is 1,742.00 PFlop/s
- This means it can perform about 1.7 quadrillion calculations per second
- For comparison, a high-end gaming PC might achieve 10-12 teraflops, which is about 170,000 times less powerful
Brain: It uses AMD's 4th Gen EPYC processors running at 1.8GHz, which are specialized server processors designed for this kind of massive computing power.
Operating System: It runs on TOSS (Tri-Lab Operating System Stack), a specialized Linux-based system designed for supercomputers.
Let me know if you'd like me to explain any of these aspects in more detail!

The El Capitan is currently the world's fastest supercomputer, and here's what makes it special:
Processing Power: It has over 11 million cores (11,039,616 to be exact). To put this in perspective, a typical high-end desktop computer has 8-16 cores. So this is like having roughly 690,000 high-end desktop computers working together! [1]
Performance: The "PFlop/s" numbers you see (1,742.00 and 2,746.38) refer to quadrillions of calculations per second. This means El Capitan can perform about 1.7 quadrillion calculations per second in real-world performance, with a theoretical peak of 2.7 quadrillion calculations per second. [1]
Power Usage: It consumes about 29.6 megawatts of power (29,580.98 kW), which is enough to power roughly 24,650 average American homes! [1]
Brain: It uses AMD's 4th Gen EPYC processors running at 1.8GHz, combined with AMD Instinct MI300A accelerators, which are specialized chips for artificial intelligence and scientific calculations. [1]
Installation: It's a brand new system, installed in 2024 at a Department of Energy facility (DOE/NNSA/LLNL).
Think of it as a city-sized calculator that can solve incredibly complex problems like climate modeling, nuclear simulations, or artificial intelligence tasks that would take regular computers years or even centuries to complete.
As you can see, it repeats itself, in this case almost exactly. I asked a follow up question about DRAM and procesor speed and got this in response:
Let me help explain these interesting points:
About the 1.8GHz vs 4GHz:
- The lower clock speed is actually intentional and there are good reasons for it:
- Power efficiency: Running at lower clock speeds generates less heat and uses less power, which is crucial when you have millions of cores running simultaneously. [1]
- Parallelism: Instead of having fewer fast cores, supercomputers focus on having many cores working together. El Capitan has over 11 million cores working in parallel! [1]
- Specialized Architecture: The AMD MI300A accelerators in El Capitan are specifically designed for parallel scientific computing, so they don't need high clock speeds to achieve incredible performance. [1]
Regarding DRAM:
Let me check the specifications for you.
Good question! The 1.8GHz vs 4GHz comparison is a bit misleading, and here's why:
Clock Speed vs Efficiency: Supercomputers often run at lower clock speeds deliberately because:
- They prioritize energy efficiency over raw speed
- They generate less heat (important when you have millions of cores)
- They're optimized for parallel processing rather than single-thread performance [1]
Different Design Goals:
- Your home CPU is designed for burst performance and single-thread tasks
- Supercomputer CPUs are designed for sustained, parallel performance across many cores
- El Capitan has over 11 million cores working together, while your CPU might have 8-16 cores [1]
As for DRAM, while it's not shown in the specs image, El Capitan uses the AMD MI300A accelerators which combine CPU and GPU with HBM3 (High Bandwidth Memory) in a single package. Each MI300A chip includes 128GB of this high-speed memory. The total system memory would be massive, likely in the petabyte range, but the exact number isn't publicly listed in these specs. [1]
The memory architecture is actually quite different from your home PC - it's designed for extremely high bandwidth and parallel access rather than the traditional DRAM setup you'd find in a personal computer.
Here its repeating itself again, but this time its not exact. Not only is it "fancified" with indentations and such, but it also doesn't make sense as it says "Regarding DRAM" but then goes on to talk about the processor, only returning to DRAM at the end.
Something up with the pre-prompt?
I expected it to just give one answer =)
