The numbers on super computers are amazing. They are all so huge that it's just really hard for your brain to 'get it'.

Jesus, subaru bajas near me have been selling at around 8 grand for the base model with 150k miles on them. A turbo was going for nearly 11k. The only one currently on craigslist is a 2003 for 9.5k with 100k miles. Thats insane for a ~10 year old car that wasn't that popular to begin with.

Anymore its as much for technical accomplishment as anything else, distributed computing has largely eclipsed individual supercomputing (and FWIW most new "supercomputers" are largely just a distributed computing setup with everything in the same datacenter.) I'm sure there's some things that need a shitload of raw processing power and can't be split up into smaller pieces of data to be processed by someone's home PC's spare CPU cycles or offloaded onto multiple purpose-built machines, but the need for a single god-tier supercomputer isn't nearly what it was 15-20 years ago.

NitroSpazzz posted:This. Instead of simulating things half-assed they simulate every atom or spec of dust or whatever else. One of the systems I worked in Germany last year was used to simulate how the placement of a building downtown contributed to dust from something ending up where it shouldn't. Yeah, I helped do HPC babysitting and data access improvement cycles. I miss doing HPC stuff. Titan gets used a lot for....explosions of the nuclear type, or at least it did till it got moved onto the new cluster they are building. Its awesome to see what they simulate up at Oak Ridge.
