You can buy upload credit with seeding bonus on some trackers, and there are nearly always freeleech downloads that don’t count against your downloads, but do count for uploads. It’s usually quite easy to maintain a ratio.

I’ve worked on several systems that had enough flop/s to make it in the top 5-10, but for which we never submitted benchmarks. Sometimes their backend network layout technically would make them several smaller clusters for an HPL run,

You still need to traverse physical segments in the wireless path: think receiving dish to the next transmitting dish, the end of the path to get from the trading systems onto the roof and into to the first dish, etc. Every nanosecond count

I think it’s a way of keeping the museum’s single most popular piece of art on display whilst working it. I think most museums would remove it for a while, but so many people come specifically to see this painting that they want to keep it

Same. That sounds like a way to make that relationship between front office and back office as toxic and unproductive as possible.

Or have them set up in a way that makes them hard to run full-system benchmarks on. I can think of a couple of financial firms that have clusters that would rate on the Top 10, but a) as you suspected, they’re too busy running the money pri

Do you have issues with other rollerball pens? I’m also left-handed, and really struggle with them (especially the G2). My issues seem to be that when I’m pushing the point across the paper, rather than pulling it across like a right-hander

In the financial industry, you don’t get your bonus when you’re on garden leave. This is usually the majority of your pay, so while it’s definitely nice to be paid to do nothing (I’m on garden leave currently until next September), you’re n

I’m not sure I understand what you mean. I’ve run HPC clusters for a long time now, and node failures are just a fact of life. If 3 or 4 nodes of your 500 node cluster are down for a few days while you wait for RMA parts to arrive, you have

Not in the context the person you responded to meant it. Yes, you can very easily get 50GB/s from a few NVMe devices on a single box. Getting 50GB/s on a POSIX-ish filesystem exported to 1000 servers is very possible and common, b

This is tangential to your point, but I’ll just mention that Azure has some properly specced out HPC gear: IB, FPGAs, the works. You used to be able to get time on a Cray XC with an Ares interconnect, but I never have occasion to use it, so
