U.S. now fastest computer in the world and first ever Exascale computer
Jun 5, 2022 21:42:03 #
The No. 1 spot is now held by the Frontier system at Oak Ridge National Laboratory (ORNL) in the US. Based on the latest HPE Cray EX235a architecture and equipped with AMD EPYC 64C 2GHz processors, the system has 8,730,112 total cores, a power efficiency rating of 52.23 gigaflops/watt, and relies on gigabit ethernet for data transfer.
However, a recent development to the Frontier system has allowed the machine to surpass the 1 exaflop barrier. With an exact HPL score of 1.102 Exaflop/s, Frontier is not only the most powerful supercomputer to ever exist – it’s also the first true exascale machine.

Could this be a military type of computer for Norad?
Traditionally, the fastest supercomputers are used for nuclear research including modeling of nuclear weapons since testing is no longer being carried on. They are also used for plasma, medical/drug, astrophysics and weather modeling / research and other open science. Since ORNL and this computer are the property of the Dept of Energy (read nuclear weapons and nuclear research), you can draw your own conclusions.

So as super duper exta flapping as that thing is, if the power goes out, it stops working, right? Just like when the power went out and my Timex Sinclair ground to a halt. I think that no matter how wonderfully powerful a computer is, it might be smart to keep pencil and paper on hand just in case.

TriX,
Wouldn't fibre optic be a better transfer medium???

You are confusing the protocol for the conductor.
Gigabits/second is data transfer rate, commonly called “bandwidth”.
“Ethernet” is layspeak for TCP/IP data transfer protocol.
“One gigabit Ethernet” can travel over fiber optic cable, radio or metallic conductor.
I would suspect that machine transfers data via silver busses, with the fewest connections and shortest physical distance possible.
At those computational speeds, the speed of light becomes a limiting factor.

That write up left out the speed of the Gbit Slingshot Interface. Frontier uses HPE / Cray Slingshot interconnect that is either 100 or 200 Gbit - they left off the 100 or 200 part. In General, big machines have typically used Infiniband (IB), but since HPE /Cray has begun to dominate big machines, their Slingshot Ethernet protocol interface has become popular. I’ll have to dig a little deeper to find whether the actual physical transport is copper or Fibre, but I’d bet on Fibre. Generally with Infiniband and 100/200Gbit Enet, the switch ports, which are an electrical interface. accommodate plug-in SFP or GBICS which interface the physical cabling to the switch and are available in either Fibre or copper. One of the big downsides of copper is that the cables are great antennas and radiate RF well up into the GHZ region, which not only allows potential eavesdropping on the data transfer, but produces wide band RF noise interference you can hear a long way away. Here’s more on the Slingshot interconnect: https://www.hpe.com/us/en/compute/hpc/slingshot-interconnect.html

I use "and relies on gigabit ethernet for data transfer" for transfer between PCs for doing backups.

Eventually, these things will become smart enough to believe humans are a virus on the earth and will launch a nuclear attack that will wipe out all human life on earth. They won't understand it will wipe out all life due to nuclear winter nor will it understand that without humans so many systems will fail that they will doom themselves.
