In reply to Cathal O Brien. Fair enough. I was just giving people a frame of reference.

MN5 has two partitions: a 45PF General Purpose partition and and a 230PF Accelerated partition. This article seems to leave out the Accelerated partition when it compares MN5 to thrown away rounding digits

In the 2007 era Barcelona Supercomputing Center had an IBM super located in an old Catholic church. The racks were in a big glass enclosure where the pews were. The photos of it were quite beautiful. Sadly I did not get to visit it.

I love this integrated aspect of ElCapitan’s MI300As where CPUs and GPUs are packaged together. The improved communications (and arch I guess), relative to Frontier, seem to give El Cap a 33% better Rpeak and (currently) 29% better Rmax, with just 22% more cores and 20% more juice. That’s clearly going in the right direction!

I wonder what would happen if the machine was run above 1.8 GHz, at something closer to the 2.1 GHz max of the GPUs, and 3.7 GHz max of the CPUs ( https://www.amd.com/en/products/accelerators/instinct/mi300/mi300a.html )?

El Capitan will surely do well modeling limited yield nuclear weapons. Really hoping he other side is in agreement on minimizing yield as much as possible. Russia and the US once tested and even deployed ICBMs with yields in the tens of megatons. At least the US tries to keep weapons below 2Mt, not sure about Russia and China. The bigger ones aren’t suitable for MIRV anyway.

In reply to Keith Shields. That makes El Cap doubly cool IMHO ... first for its direct liquid-cooling, and second for its top-hat shaped cabinets in which rabbits are fully integrated, for NVM-Express magic wand extraction and storage, with nothing up the sleeves and long coat tail distributions of the more typical data prestidigitations (or so I'm told)! 8^p

The great honour HPC Elcapitan total functional enormous machine its total merit by H. Packard Enterprise, a hightech confident corporation. !!!

As a point of clarification, the “rabbit” modules are fully integrated into the existing 87 EX compute cabinets in El Cap. There are no additional racks dedicated solely to the rabbits.
