  1. I don't believe there is a "standardized" definition of what a supercomputer is - it's kind of a fluid concept, because you can't simply say "It needs to be faster than x number of TFLOPS", because that number will always be changing. According to Wikipedia, a Supercomputer is simply a computer that is a lot more powerful than a traditional general-purpose computer. According to dictionary.com, a Supercomputer is a "very fast, powerful mainframe computer, used in advanced military and scientific applications." Personally, I would say the Dictionary.com definition is outdated. Mainframes generally refer to systems that run thin clients and do all the central processing in one location for many users - while some supercomputers are definitely Mainframes, others, won't be. Further, it's too specific about being for Military and Scientific applications. Many supercomputers are used for retail/data crunching/engineering, etc, that aren't really scientific applications. I doubt we'll find consensus about what the actual definition should be.
  2. Indeed, which is why we should hold off on statements like "Well it's not really a super computer!" Until we actually learn anything of substance about it. We really know very little right now.
  3. It's all about comparisons. If you look at a desktop computer - say, an i7-7700K - this CPU has a GFLOPS rating of around 40 GFLOPS. The HPE ISS "Super Computer" has a rating of ~1 FLOPS. By comparison, the i7 is 0.04 TFLOPS. Whether they could just drop a GPU in there and get 1 FLOPS very easily (or 2 or 5 or 12 TFLOPS depending on the GPU) - sure maybe, but perhaps the datasets they intend to run don't mix very well with GPU architecture - perhaps they are more suited for CPU's to execute. We also don't know whether they actually mean TFLOPS - because TFLOPS is Trillion floating point (implied 32-bit) operations per second. When they said it could do one trillion calculations - that could be any time of calculation/math. it could be FP64 or FP32 or FP16 or something totally different. Finally, we don't know whether that quote refers to the CPU only, or the total system performance.
  4. No - not in an easy way. Parity RAID on ZFS does not allow you to grow the number of drives. You either have to swap out drives one at a time with a larger one, rebuilding the array in between each swap (This will take a long time, no doubt). Or you can add a second complete array and stripe them together (This would be a ZFS equivalent of RAID 50). Neither of those are ideal.
  5. I agree with @Jarsky - if you don't want or need ZFS, then the main advantage of FreeNAS is gone - sure it's still a decent NAS OS, but there are comparable alternatives, such as Open Media Vault.
  6. There is no set policy to answer your question - each insurance company has their own policies and different criteria. Many policies now come with a clause that says your rate is guaranteed not to go up if you were not at fault. At-fault accidents, however, will generally not have that kind of guarantee. Now and then, I'm sure they'll make an exception, but I imagine that in most cases, the insurance rate will rise. Assuming your Aunt has a good driving record and has been insured for a long time, the increase will likely be fairly small.
  7. Definitely sounds like a hardware or driver problem. I'm leaning more towards a driver issue. On the laptops where the extra NIC's are missing, can you try plugging the dock in, and scan for hardware changes inside the Device Manager?
  8. You literally can attach any switch at all to that. Whether that means a push button, or a toggle switch, or a light switch, or an actual door bell - your choice. And to wire it up, unless you buy something fancier, it'll just be a matter of connecting one wire the positive lead and the other wire to the negative lead. In this case, polarity (Which wire is hooked up to positive vs negative on the switch) shouldn't matter - since it's a simple open/close switch that's needed.
  9. Yep doing a step-by-step check is the way to do it. Very time consuming, but literally anytime you make a change, you should check to see if the dock still works, until you find out it doesn't work. Then get another spare and test to see if it's reproducible. Can you find a general list of what networking equipment is in your network? On the network side, a really fucked up Firewall ACL (Access Control List) might cause issues, flagging certain computers and blocking them, vs letting others go. VLAN's could be an issue, but this should be consistent (Eg: if it works in the IT Office, it should always work in the IT Office). Are these computers all using DHCP? If so, what is the DHCP Server? Is it a hardware device (Router, layer 3 switch, etc), or a Windows/Linux Server? Are there multiple subnets (Eg: 192.168.1.x + 192.168.2.x) or is everyone on the same IP range (Eg: 192.168.1.x)?
  10. What happens if you take that users machine and brought it and the dock back to the IT office and tested the entire end-user setup back there?
  11. Swapping a WD Blue for a Seagate isn't a terrible choice - the Seagate may provide marginally better performance. Both are pretty good quality drives and should last just as long. Some people simply think they're giving you help by suggesting things you might not have considered. If they post off topic and don't respond to your initial question, just report the posts and/or ask them to stay on topic.
  12. Please keep in mind that Steam Link provides a pretty terrible HTPC experience. It does gaming quite well, if you want to stream games off of another PC, but the rest of the HTPC experience: Watching streaming apps/sites, watching local movies, etc - is going to be very subpar. If you're gonna use Steam In-Home streaming for an HTPC, I would suggest you're better off using full-blown low-end PC's instead of SteamLink's. You'll be able to install Plex or Kodi or some other HTPC Front-End that will be by far more user friendly. You can "stream" Kodi (and probably Plex) over Steam In-Home streaming on the SteamLink by adding it to Steam as a Non-Steam App, but it's janky as fuck and why are you streaming a stream? Total waste of internal bandwidth and wasted processing power on the VM. Hell, you'd be better off doing SteamLink + a Roku/Chromecast/Apple TV/Android box.
  13. Here's the thing: Making an off topic post in a thread is actually against the Community Standards. If someone does that, simply report the post, and move on. Eventually a mod will come in and either delete the off topic posts, or remind people to stay on topic.
  14. I don't have FPC so I cannot confirm, but you'd likely be alright for the lowest quality streaming setting. However, you can actually straight up just download the video file and play it locally, assuming that you didn't need to watch it "in real time", and could wait for a download to complete.
  15. The current APU's are actually pretty decent little CPU's if you don't need something high powered. But yes, as soon as the Ryzen based APU's come out, the Excavator based ones will be outdated and no doubt AMD will stop selling them almost immediately.
