Anyone know the reason for the dominance of Power processors in the top 10 other than it's from IBM and they get a lot of contracts for HPC?

#102The site of the organisation responsible for assessing the fastest computers in the world succumbs to the hacker news hug of death.

#103Really wish Fujitsu sold a developer kit with an A64fx chip - its the only shipping ARM chip with SVE that I know of and I would love to get my hands on one to play with.
No kidding! I don't have any sense of how much these cost to manufacture. There ought to be a market for a A64fx based rackmount server system. If the price isn't outrageous, I'd love to see these sold as an SBC.

#104Not to be dismissive, but can't anyone "build" the biggest supercomputer by reserving enough instances at AWS or GCP? I'm sure that AWS or GCP would like to encourage this competition, but it seems a bit, well, boring.
The ranking is calculated based on the Linpack benchmark. Being a parallel application, performance is not simply scaled to number of processors; the network interconnect is hugely important. Now, although Linpack is a better evaluation metric for a supercomputer than simply totaling up # of processors and RAM size, it's still a very specific benchmark of questionable real-world utility; people like it because it giv…

#105I cannot think of any plausible way in which Apple could have influenced the date of this announcement, but the timing, given what is expected to be announced later today, is uncanny.

Simple, human error and no code review process for your production environment. Something similar happened to a huge retailer here in Austria where just typing your username without password would log you in. Reason? An intern committed debug code to production and nobody noticed. In my book that's not the fault of the intern but the fault of the CTO/$TECH_LEAD that hasn't implemented and religiously uphold a code re…
It is the fault of both. Interns are not stupid and so they have to carry the burden of their mistakes too.
You can’t fault people for making simple mistakes or you’ll end up with an organization where nothing gets done.

#107Edit: seems to be a Fujitsu designed interconnect [0]. Wonder how much of the overall performance is dependent on the difference in communication.

Heheh, from the guys who use variables such as Vo ,tm,max_p, this guy expect them to RTFM.
Those are perfectly reasonable names since they're standard convention in engineering and science. It's like using i, j, and k for index variables in iterators; the meaning is clear due to convention.

To be fair, I wouldn't host my website on my world-class supercomputer either, if I had one...
To be even fairer, I've served a shit ton of traffic on a small DigitalOcean droplet and never had issues because my stack is reasonable.
Sure some principals may be common due to the distributed network but the actual practical tools have nothing in common.

#110Is there information on how the Fugaku machines are connected together? The highest performing Power9 ones seem to use InfiniBand, but is that still true with the ARM devices?
