However, the GO drives typically do not have a SATA connection on the drive which means you are hosed if the enclosure shits the bed. We are just trying to look out for your data.

cisco privilege posted:My motorola phone is thin as hell and apparently supports wireless charging. Without any kind of wireless quick charge though it's easier just to plug it into the quickcharge2.0 adapter for 15 minutes every couple days. This is a big limiting factor for Qi right now: the power profiles for many of the charging stations are really, really low. Which means either they charge slowly, or quite frequently they don't charge at all because they're "too far away." I'm sorry, lovely Qi charger, but if the 3mm of my slim-profile rubber case is "too far" then you should probably look into sucking less.

I do plan to get a wireless charger at some point but they're definitely not something for quick use. Some newer phones are coming out with a quickcharge wireless option that seems neat but for normal use it doesn't seem as versatile as just having a couple cable chargers or a USB cable around.

I know, I was just making a John Oliver joke about British dentistry. The stuff I have on them isn't important, it's just HTPC stuff that I keep instead of deleting because of a 3 day bandwidth limit of 20gb, so any time I download something to watch I keep it. My only other options at this point are to open up those HDD's like Vulgar said and hope I can salvage them by putting them in a NAS or replacing them with much bigger internals, but 8TB internals on Newegg are $500+ (except a Seagate that apparently has a huge failure rate) so that'd be $750 to $1,500 to replace what I have now. I didn't just go out and buy a poo poo load of HDD's at one time to do this, I've just been adding them over the years as I fill one up. I'd ideally prefer to replace them when/if 3.1 external HDD's come out and power themselves, then I could just get three 10TB's, free up more space and lose a poo poo load of wires, but it's not that important to me since I don't actually see any of them in an entertainment shelf. I can't rule out I'll end up causing the next California wildfire though.

I don't know much of anything in this space but not to long ago I remember hearing the complaints about CUDA is that it sucks to write for, won't give you the performance boost they claim unless you write it correctly, requires you to hire expensive software guys in order to write and maintain good CUDA code. I'm assuming those complaints were overblown?

Also, have fun if you don't use C as your scientific language of choice. CUDA Fortran exists, but only for one proprietary compiler and is just as much of a pain in the dick to code for. The next HPC purchase I make will probably be a Phi.

I'm assuming those complaints were overblown? Software engineers will work 120 hours a week for their salary they cannot spend, so those complaints are silly for the beneficiaries of the written code. No end-user cares that it is hard, as long as you can make your currency swap 430 milliseconds faster than the other guy. Also, from my understanding, Phi isn't easier to code for if you want it to be remotely comparable to Tesla -- you're just going from one PITA to another PITA if you want the same performance out of a Phi as you do out of a CUDA board properly caressed by good CUDA code.

If someone wanted me to use Cuda Fortran I'd probably quit my job. Having to deal with fortran code frequently is unfortunate enough, but taking something that is well suited to one language and bringing it to another language it has no business being associated with would really irk me. There's a reason Fortran isn't used for systems programming and C is. With that said, I'd work on a fortran project that used CUDA but it would have to be called through a binding/dll of some kind and not be done in CUDA Fortran.

So I'm running a 4670k in my year-old machine, and I just had to do a system restore to resolve a very odd bug. Ever since my last windows 10 update a couple of days ago, my computer had been running really sluggishly and experiencing a really high CPU-load, even after I ran malware and virus scans. Eventually I got fed up and looked more closely at RealTemp and noticed that, instead of running at 3.4 GHz like it was supposed to, my processor was running at only 785ish MHz - and it was locked there constantly, regardless of what the CPU load was. A system restore seems to have resolved the issue, but I was curious - does anyone know how in the gently caress that sort of thing happens?

A bunch of very, very slow cores (1GHz, no branch prediction or OOO, awkward memory access.) You need to vectorize and multithread your code to get anywhere near optimal performance, which may be no easier than implementing a CUDA kernel. The nice thing is that by the time you optimize your code for the Phi it is usually much faster for regular X86. You could argue that it might make sense to buy Phis now that they're $200 to prototype your apps in native mode for KNL, which is going to address many of the KNC architecture issues, if you are going to be running on one of the KNL-based supers coming online next year or 2017.

Check the power options, make sure it's not set to "power saving" or the like. vv Yeah, you'd think it's only for laptops, but since desktop CPUs also use the same speedstep tech these days (for years now), they can also be told to clock down by the OS.

Anyway, like I said, I did a system restore to fix the problem, so while it's not on Power Saver now I can't really say what it was like before the restore. That would make the most sense, though.

What you're telling us sounds very similar to a problem associated with throttling down to >9watts of power usage, and that throttle is done by the DPTF driver when Windows 10 thinks you're putting yourself in a low power state. When you wake from sleep, Windows doesn't talk to the DPTF driver effectively, and so you remain at that 9watt state. Happens on my Lenovo Yoga Pro 2. I had to edit the Batch file for the driver so that the lowest limit would be 11 watts, but that is for a 4210U proc.

Spiritus Nox posted:Interesting. Any reason to think it'll happen again now that I've done the system restore? So you went back down to Windows 8.1? In all honesty, check your BIOS. You don't need DPTF to throttle down -- it is meant for chromebooks and other ultraportables to save power by getting lower than Lil Jon is even comfortable with. If you have a BIOS setting for DPTF, turn it off. Maybe that will help.

Couldn't take waiting for the 6700 anymore and got a 6600, probably use it until 6700's are either abundant or wait for an extreme version or a refresh. Paired it with a Maximus Hero because I'm subhuman garbage who wastes money. Also newegg eggpoints have to be the dumbest promotion I've ever seen. Almost nothing they sell gives them, what does give them gives you almost none, they're almost completely worthless if you do have them, and they have to be spent within 90 days.
