Intel Foveros

The key part of this discussion however is this block diagram that was on one of the Intel slides. Here we see a single ‘Big CPU’ with 0.5 MB of private medium level cache, four ‘Small CPU’s with a shared 1.5 MB L2 cache, an uncore that has 4MB of last level cache, a quad-channel memory controller (4x16-bit) with support for LPDDR4, a 64 EU design with Gen11 graphics, the Gen 11.5 display controller, a new IPU, MIPI support with DisplayPort 1.4, and all of this in a tiny package.

Seriously though, this has the potential to be a large revenue stream for Intel. They’ve made this chip, which allows the cores to enter C6 sleep states when not in use, that has a die size smaller than 12x12mm (144 mm2), and target the sub-7W fanless device market. That’s with a big Core, four Atom cores, and a GT2 64 EU design.

Maybe this would run Seti faster than the Linxu/ARM systems (I think they are phones?) I see here and there?

Has anyone else noticed that there seem to be a lot more of the thingies, spinning stars, disk drives, etc after their names on the message boards. Seems like I have all three now, only one missing is the non-spinning star????

I finally got a star last week. My first board tchotchke

Has anyone else noticed that there seem to be a lot more of the thingies, spinning stars, disk drives, etc after their names on the message boards. Seems like I have all three now, only one missing is the non-spinning star????

And look, no sooner did I question the awards, and they have gone away.
And my star should be coming back shortly as I have just done my yearly donation.

Phoronix has taken a look at the Titan RTX, compute performance.
In some cases it has double the performance of the GTX 1080Ti. Given it's running software that's yet to be optimised for it's architecture, the potential of the RTX series really is quite impressive.

Yes, and your star not moving star won't show. However the extra GPU card went away when your not moving star should have shown up. BUG!

I PM'd Eric about it some time ago and they know but it isn't a priority. I much want them working on getting the Parks data out rather than messing with donation icons.

So, software issues.

I am corresponding with someone in PM and he asked an interesting question.

"If you know of someplace I can get a pre-built bare-bones system with good quality parts with warranties, please let me know."

He has back issues so leaning over to assemble a system from scratch will be a problem. Has anyone found a place that would create at least a good high-end barebones seti system?

You are looking for a system builder. There are hundreds. Try and find a local one for your area or if you have to, resort to a online system builder. Try Google.com. First one that comes to mind is Puget Systems which has been around forever and is often featured in online reviews.

That's me that Tom is in the PM conversation with.

I won't tell you the exact location I'm from, let's just say the middle of nowhere is the most polite version.

There is nothing within 25 miles of me that will custom build a computer that know anything about liquid cooling. The closest place is an hour away and when I told them I wanted 4 GPUs they automatically started talking about SLI. I told them I never said anything about SLI, you came up with that on your own and then I started wondered what else they would make up so I decided they weren't for me.

I've looked at about a dozen places online. Have you guys ever looked at the warranties from these places? Some force you to send your system back to them for a yearly cleaning. Some force you to allow them to do a remote connection to your computer so they can "clean and tweak" your system. Others force you to send your system to them on your dime both ways so they can install upgrades that you can only buy from them. All this is of course only if you want to keep your warranty.

To me, that's all just ridiculous. Maybe not to anyone else.

In my messed up mind, it's similar to modifying your auto. The law says that just because you put different tires on your truck, the manufacturer can't automatically deny a warranty claim on a blown engine. Same thing with a programmer. The truck manufacturer has to PROVE that is what caused the engine to blow. But you don't have to go back to the dealer for any service at all. not even regular service like oil changes.

So why should anyone have to jump through hoops to keep a warranty on a computer they spent their hard earned money for if you don't have to on an auto? If you want to argue with me, please do so in PM so everyone doesn't have to read it.

And at the prices these places want, why won't they stand behind their work? They usually include a 1 year warranty but a LOT of the components come with a 3 year warranty or maybe longer. But the end-user has to take that up with the component manufacturer themselves. Most of the time we don't get a choice in who made the parts that are used to build the system and if we do ask for a brand they don't normally use, it costs extra even if it would cost less on newegg. But the system builder will refuse to help you after their normal 1 year or whatever extra you pay them for runs out.

Yep, I see things differently than most people. I'm proud of that.
I don't think outside the box. I don't even see a box to begin with. I'm proud of that also.
I ain't lost my mind, it got scared and run away.
I'm a disabled veteran and you can guess which part is disabled! :)

What kind of GPUs are we talking about? High end GPUs? I'm thinking about the total wattage out of the wall for the system. I've had and still do have a couple of MegaCrunchers running but found that the load on the wall socket something to worry about. Already had to replace the plug, wiring and circuit breakers on 2 different machines. Not to mention the PSU in both machines since then.

Best option is a dedicated power outlet linked only to its' own circuit breaker in the box. That's what I ended up doing. Keith can give you more ideas on that. If you go with Midrange GPUs then it shouldn't be an issue depending on what they are.

My 2 cents..

You will be hard pressed to find a System Builder that will Warranty against the labour for replacement of an 'in warranty' component within that system unless you pay ALOT of money for it. Tearing down a 4 GPU water cooled system just to do testing is a day long job - just as a start. For them to warranty labour for a flaky GPU replacement isn't going to happen.

You are probably better to ask them for an 'out the door' build with components you supply.
Leak tested and running, but nothing more. Just a per hour for assembly.

I should also have mentioned own and live in a mobile home from the mid 1980s, read that as the wiring is equivalent to a 1720s home in some third world country. I've had to have independent circuits ran from separate breakers back here years ago. That solved many of my problems as soon as I started using them. Using a UPS solved even more. I have room for more breakers in the box and the incoming power to use a few more of them. Illinois doesn't require, or didn't, any kind of certificate or license for electrical work so anyone can do it.

I was thinking of starting out with GPUs toward the lower end of current models, 1070s or such. But as $ permits working up to higher and higher end cards, then using the lower end cards for other, dedicated crunchers.

I'm wanting everything liquid cooled which only adds to the power requirements.

I forget the size of the PSU, but it was connected to a UPS of more than sufficient size, on my current system (i7-2600s, 8GB RAM, 1 HDD at the time, and a 660TI, all air cooled) and I don't know what the right terminology is, but I guess I got the power cord for the PSU so hot the PC stopped working. Wouldn't turn on at all. Got to checking and the insulation was dried out a brittle, that's why I think it not only got hot, it stayed hot for quite a while. This was the cord that came with that PSU new. Now, I never use the cord that comes with a PSU, I always go with a larger gauge cord and replace them every couple of years even if they look/feel/work good.

I've even though about a dedicated "drop" for this room from my local power company. 100 AMP from them should get me for a while with what I've got currently got plus the one new system and a dedicated A/C for the room. My side will be 200 AMP ready so I don't have to upgrade it in the future if/when I get more machines.

I've got another question for ya'll. Anyone know anything about putting a server rack in a mobile home? I've talked to a couple people that install them in businesses but can't help me here. Need a freestanding rack as I have no idea if this thing even has any support in the ceiling.

Full blown water cooled loops don't allow for easy swapping of parts. Plus you need a cooling loop in the system you are moving it to.
You may want to consider Hybrids, which work very well.
For a 1070 https://www.evga.com/products/product.aspx?pn=08G-P4-6278-KR
And an example for the CPU https://www.evga.com/products/product.aspx?pn=400-HY-CL28-V1
They are much much easier to work with and do not ever require refilling/maintenance.

Take a look at Zalsters Image in this thread - That is 4 EVGA 1080Ti Hybrids in (I think) a Thermaltake case.
He could tell you exactly what fans, etc would be needed to put them in the same case ... he has 4 duplicate systems ... show off!

Four high end gpus, even 1070's are going to pull north of 850W. My four card hosts always are north of 1000W. Put two such hosts on the same circuit and you have already exceeded the rating for a standard 15A house breaker. The wiring in the wall from the breaker panel to the outlet is usually the most limiting factor. Standard house wiring, especially from the age of your home was 14 gauge at best maybe even 16 gauge in a mobile home. Also the construction period calls into question if aluminum wiring was used which is its own major headache.

To supply power to a high end 4 card host with 1080Ti's would mandatorily require minimum 12ga wire and a 20A breaker preferably with nothing else on the circuit. If building out a new location and breaker panel installation for a dedicated high current draw host, the best solution would be a 12ga wire pull to a dedicated 240V outlet on a 20A breaker. The power supplies auto adjust to the higher voltage and the current draw is halved. The duplex 240V outlet would support two such hosts.

I've put a couple of 42U server racks into "portacabins" over the years. Both were against internal walls, and ended over a foot below the ceiling. Back wall securing is much easier to achieve than over-head ceiling, and is more stable. In any such installation you have to consider the floor loading, for most "temporary" structures there are two figures, the "per square foot" and the point. The "per square foot" is the maximum load per square foot (or yard), this gives the maximum load the structure can support over a given area. The point load is exactly that, the load you can apply to a small area, say with a small chair foot - this is how hard it is to make a hole in the floor with your rack. You can do little about the former, but for the latter putting the rack onto a couple of layers of three-quarter inch thick ply wood will almost certainly enable a fully loaded 42U rack to be put on a typical floor and not have it punch through.
"Proper" freestanding racks are notoriously unstable, so I wouldn't drop one in anywhere - always secure racks to the wall behind, the last thing you want is your server farm to end up on top of you if you have the misfortune to trip over that trailing shoe lace you've meant to do up for the last hour or so :-(
For most "domestic" installations a "professional" server rack is way over the top as you probably only have a few bits to mount. Far better is to look for garage/shed storage cupboards or shelves, they are much less expensive, and much easier to install, not to mention less expensive.

("portacabin" - A relatively light weight construction portable cabin, often used for site offices and the like - very similar construction to a mobile home but a lot less luxurious)
