Comment Re:Seems to still be architecturaly-gimped (Score 3, Interesting) 46

Quick clarification: Not the memory controller was gimped, but how processors communicated and shared stuff out of their memory to other processors was gimped. And the E7 v3 looks to have the same limitation. Pumping up QPI speed might help alleviate that SOME but nowhere near what's needed for multiple socket multiple GPU configs in a single non-nodal system.

Comment Seems to still be architecturaly-gimped (Score 3, Interesting) 46

It appears that they didn't do much to the QPI besides boost the speed a bit. That's not going to fare well in HPC stuff. The reason I didn't use the V2 E7-8*** line was because due to how gimped the memory architecture was, you could run 2 socket 4 GPU, 4 socket 2 GPU, but not 4/4.

It was cheaper, and just as effective, to go with the E5 instead, and make multiple node systems into a single box, instead. 8 socket, 12 GPU. Fuck yea.

Exactly.

The ruling is based on a false premise.

I know what they look like, I've coded GIS software for cell providers, I even know what most of the hidden ones look like, and how the log files work (since I used them), but most people think it's a magic device powered by fairy dust that doesn't track them until they "turn it on" (it's actually on unless you specifically power it off).

Comment Stop enabling swap (Score 2) 99

it also seems to do well with low-memory systems (lots of the current models have just 2GB, which brings many Linux distros to a disk-swapping crawl), and starts up nicely quick.

I am in the midst of building a CarPC right now, as parts trickle in from far-flung regions of the globe, which is to say mostly HK. I'm saving my money for the display so it's a budget build based on a Boxer DA078L motherboard. I downgraded the processor to IIRC a X2 3800+ from a 3900+ because the specific processor model I ordered had almost 30W lower TDP, bringing the total system TDP down well under 100W which meant I could use a PicoPSU 120. I haven't tested my el cheapo 300W (headroom! which I will leave unused) boost-buck regulator yet, that's next. It has 2GB of RAM and I installed Kodibuntu, then installed navit. It comes with chromium and I am running the system on an 8GB CF card, currently in a USB adapter and soon in a SATA adapter. Maybe someday I'll buy it a real SSD but again, this is just a pocket change build based on something I had already. A $8 low-profile AM2/3 cooler is coming.

Why care? I can run Kodi and navit at the same time with no problems, using compiz as my window manager. and it can easily run chromium under LXDE. And I have no swap whatsoever. It would be dog-slow on my CF card (It's a "133X" Transcend, whatever that means) and I don't want to beat up my flash device anyway.

2GB is a lot of RAM. It seems like it isn't because of all the crap we run these days. But 2GB will actually go hilariously far if you use a limited desktop environment, or in fact none at all. If you just put the smallest Linux you can come up with (puppy?) into a partition with chromium, make init keep X running and make X keep chromium running, you'll have what you're looking for. I presume the only reason to want this is to have it as a multiboot option, since as others have said, if you wanted an actual chromebook you would have bought one. To come back around to my long introductory paragraph, I installed Kodibuntu when I wanted automotive navigation. That seems dumb, but it makes sense in the view of trying not to buy stuff. I also wanted more CPU power and didn't care about GPU power, so it made sense to me not to buy a Pi 2 and use a turnkey solution. (That's where I got the pointer to the skin I'm using.)

Comment Re:disable swap (Score 2) 99

As you said, swap isn't needed so much, but there are still good reasons to have some around.

There's only one: you have very little RAM. Then you may well need to use some swap to get a modern browser running well enough to hit newegg or eBay and buy some RAM.

Besides the usual graceful degradation argument

No. Swap causes graceless degradation. It's not so bad if you have SSD or hybrid disk, because it can handle seeking all over hell when it happens. But it's better to just let the OOM killer murder the out-of-control application. Save early, save often.

it can be particularly handy for portables as a suspend partition.

There's nothing wrong with a suspend file. You could make the argument that it's possible to fill up the disk to the point where there's no room for one, but that's a feature. The computer can inform me that it cannot suspend, and let me know why. I can then decide what to do about it.

Swap was awesome back when RAM was expensive. RAM is now really cheap and you can do a hilariously huge amount of stuff with just a couple gigabytes of it and no swap. With four gigabytes of it I can run my database, map, and pbx servers in their own full-fledged VMs on top of a machine already providing other services... and still have room left over to run a Windows XP VM for automotive manuals. Now swap is just stupid, unless you know you have a specific use case where it won't unacceptably degrade performance. And frankly, if it helps you, it's probably because someone allocated a lot of memory they weren't using.

I think uPnP is cool. Obviously, so do malware authors, but I still think it's cool — if you do gaming on windows. And that's where most of the action is... It'd probably be wise to turn it off when not using it, though. I never save firewall rules automagically, so it would be easy to fire the firewall script when terminating it and know that something sensible would happen.

Comment Re:Like multiplayer? (Score 1) 104

Actually my suggestion was to let people decide whether or not to let GOG try to change it since not all users trust apps to change the firewall, not all firewalls allow apps to change it, and so on. Maybe for maximum paranoia there could be a setting that hides the uPNP option completely so nobody accidentally checks it.
