Yeah, see, that's not in-place updates, since the old crap keeps running, too. What I understand under such a term is to replace code in active processes, and that's just plain not practical.
You can't do it for an arbitrary piece of code, but it has been done for patching the Linux kernel. In fact, a company did it a while ago and was bought by Oracle. Even if you remap syscalls and bounce them around to new pages, that won't fix the problems with programs that might be referencing pointers to outdated data structures provided to them by the kernel. It especially won't help if there's been a data structure modification that requires some userspace cooperation to handle properly.

I think the implication may be that Skylake could be getting delayed because of some of the delays occurring within Broadwell.

I'd be very surprised if most Skylake consumer parts don't slip to 2H 2015. We're not going to have any Broadwell in consumer channels until 2Q 2015 now, it almost doesn't make sense to produce Broadwell at all.

The CPU will throttle itself at 99 or 100C down to like 800mhz until you stop trying to kill it. I forget the thermal limit but it might be 105C or something on the core? I wouldn't let it sit over 80C for long periods of time but 75 max is not a huge deal and that 80 is more of a personal preference thing (since the temperature monitoring isn't exactly what's on the core it could be warmer inside and I'd guess I have some bad cooling and it might get dusty and kick things up a few degrees or whatever). It's a little warm, sure, but not terrible.

If you're concerned and want lower temps the Hyper 212 EVO is like 30 bucks and goes on sale down to 25 regularly, it's just bulky and can be annoying to install if the motherboard is in the case and there's no cutout behind the cpu socket. I have an i5-4670K overclocked and the max temps I get are 68C or so with regular loads. Benchmarking and stability tools like Intel Burn Test and Prine95 can get it hotter but they're intended to do that (also don't run them if you're using adaptive voltage).

How do I know if I am using adaptive voltage?

I haven't kept close watch on the Broadwell and Skylake updates, but I would assume that the delays are due to the new process having issues. Since that's what Skylake should be on, whatever affects Broadwell process enhancements will affect Skylake. Have we ever had delays from Intel for anything besides new process problems (or that one pesky bug on Cougar Point I think it was)?

They've gone back and forth but last I remember they were going to release just mobile versions and later introduce the desktop versions. Given the schedule slip and the rather serious burns to the bottom line, I would expect them to not bother with the desktop Broadwells anymore and just push enthusiasts to pick up Skylake. Intel has given itself a little time with the Haswell-E release I suppose.

I'm now putting together a new machine, because either my motherboard, or the i7 930 @ 4.2 that lives in it has finally given up the ghost. Lots of random crashes, even after I took the overclock out. :(

Nehalem was loving BEASTMODE though.

I was hoping to hold out for Skylake, but it simply wasn't to be.

My Nehalem chip LIVES. LONG LIVE OLD poo poo. :black101:

It ended up being a bad (read: cheap OCZ) SSD causing weird-rear end crashes. New Samsung drive, and I'ts running like new.

1.3875v Vcore. I don't really remember most of the settings. I got it stable, and just used the thing. For years.

It would run really, really loving hot (~97°C at full load, and I've spiked it even higher a handful of times, on accident,) even with an Evo212. I've abused the gently caress out of this chip, and it still won't die. I think I'm going to dial it back a bit until Skylake comes out, though.

Not Overclocking at all, I just want to stress my cpu to make sure its not having any heat issues. A poster above mentioned that I should run some utilities but only if I am not on adaptive voltage.

Skylake will be a new chipset and a new memory type, and both will have a premium (probably a pretty big one for the memory)

Broadwell will socket right into existing motherboards and use existing, cheap memory.


Producing both might seem foolish, but intel has already done all the work to get broadwell to market, so the additional cost of actually making and delivering it is very small by comparison, and there is certainly a segment of the market to fulfill. We still see older pentium and core2 CPU's being made simply to meet a cost:value market niche.

I'm betting the performance of skylake and broadwell for most day to day loads, and even for most gaming loads, will be effectively identical.

As could be expected for a 270W card with no fan, cooling is *very* important for these. If you're interested, look at the Supermicro 4U passively cooled GPU/Phi chassis to see what they do.

It runs Linux. You can SSH to it.

They aren't Atom cores, they're Original Pentium (P54C) cores without out-of-order execution, 4-way hyperthreading, and an wide-rear end vector unit bolted on. Next-gen will have Atom.

You'd need to recompile Octave (the architecture is technically not 'i386/x86_64' but 'k1om'.) There's only 8 GB of RAM on-card, so there may not be enough memory. If you're doing anything but large floating-point matrix algebra you're not going to get very good individual performance (a single core is about 1/10th the performance of a desktop core on integer workloads.)

If you compile Octave with the MKL on the host or your desktop you can use the automatic offload to send large matrices to the card for processing automatically.

At $150, they're very cheap FLOPS if you can use them.

Next generation architecture is Knight's Landing, which has been announced earlier this year. The first announced delivery of systems based on those are NERSC and NNSA machines scheduled for delivery in 2016 and I'd be surprised if there was general availability before then. I'd also be surprised if they did a die shrink of Knight's Corner.

These are the low-bin Phi parts and I'd guess Intel is fire-saleing them to clear inventory / build the developer community / gently caress with NVIDIA. If they are planning a revision, Supercomputing is in three weeks, I'd expect an announcement there.

That should be plenty. These put out about the same amount of heat as a 290x and those work fine with just a single fan blower. It won't be a quiet solution but it will certainly work.
