@HardLine He actually killed the value of this test far before he stepped in. THIS DOES WORK AND ALLOT BETTER THAN SHOWN. #1 He used Dual Channel Mode Which DOUBLES THE bandwidth OF HIS RAM BASICALLY. IF you have 4GB of RAM IT IS IN SINGLE CHANNEL MODE Splitting the speed in half. #2 He used A GTX 1080 TI. Which has insanely High V-ram available. Without such a large pool of v-ram it feeds into system ram, If that is filled it feeds into the Paging file DIRECTLY... Meaning if he was using something like a GTX 1060 3GB or GTX 1050 2gb HE WOULD SEE FAR HIGHER PERFORMANCE GAINS. This is literally known by everyone who knows what they are talking about. And is even known by other KZreadrs. Example Where just a bump down in V-ram produces 20 less average FPS and shows usage numbers: @1:50 -> kzread.info/dash/bejne/Yqho166hYr2xYJc.html Note that was with a computer with 32GB OF RAM.

So I removed the 32GB Optane module and installed a 500GB 960 Evo NVMe SSD in the M.2 slot instead, and have them as separate drives, with the OS and all of the programs on the SSD, and the 2TB HDD as a separate D: drive which I manually store media files on. And this way, the NUC is running much much faster than it was with the Optane setup.

I think lots of Optane lost performance comes from Windows menagment of memory. On linux you specially format seperate partition as SWAP for memory and that could work a lot more efficient. Can we get same blender benchmark but on linux? In older video i remember that Optane there absolutly demolished NVMe, so I hope it could come closer to RAM. Also something I could suggest is testing on windows 7 zip with absurdly high compression settings on really low memory with large memory pages off and on.

Optane is such a cool technology, it's unfortunate that basically nobody seems to understand what it is and what it's supposed to do. And Intels boneheaded attempts at marketing it as a HDD buffer, which is a use case already comfortably covered by conventional Flash SSD's, doesn't help either. I fear that the lack of CPU architecture / platform-level support for this sort of mass-storageRAM intermediary type memory is going to eventually put a nail in Optanes coffin before it gets a chance to shine. If only more people understood how cool random access byte-addressable mass storage with mega low latency really is.... The Blender results in this video shows at least a glimpse of what it can do. Imagine if the hardware architecture itself inherently understood how to use this intermediary memory effectively (and understood that it is DIFFERENT from volatile RAM, because it IS and always will be), or for that matter imagine if software was written with this type of memory in mind as an option, it'd be A LOT more performant than this "fake RAM" application. And, better yet, the hardware layer doesn't have to support "Optane" specifically - as long as it just supports any byte-addressable low latency mass storage, it could make effective use of ALL of them. Because they all have the same outwards interface - their internal structure doesn't matter to the architecture at all. So you could use FeRAM / RRAM / other exotic nonvolatile RAM technologies, that do exist in the microelectronics world already, and it wouldn't matter, it would operate the same.

Memory is managed pagewise, not bytewise. This is how the memory management unit in the CPU works, has worked for decades, and this is how the operating systems work. This is not going to change, for the simple reason that for managing memory bytewise, your look-up data structure telling you which memory belongs where, to which program, to which hardware unit, would explode in size and the lookup could no longer be performed in constant time. This would be a recipe for disaster. The common page size is 4K. Operating system already has a good scope of which memory is hot and which is cold, how many accesses are there to each page every sufficiently large unit of time (around 100ms, that order of magnitude) or how long ago in these units of time the last access was, and makes decisions accordingly where to place it, either retain in RAM, put in in zRAM (compressed page storage in RAM, new to Windows 10, optionally present in Linux for ages), and there is a furthermore a hierarchy of disks and disk-like swap devices depending on their performance. A very good choice would be to expose a small mass storage device like Optane as memory-mapped IO, so data doesn't need to be copied pagewise back to RAM, instead the address directly on the storage device could be used directly in the page table and the software can continue executing with less sharp of an impact, in particular in cases where the whole page wasn't needed right away, which will often be the case in "diffusely slow" software, which is a rather common and unfortunate trait these days. Diffusely slow software is software where you can prove on paper that it should reasonably be performing a lot faster than it is, but you load up your profiler and you see... nothing in particular, nothing jumps out, there's nothing to optimise. Usually it comes down to unfortunate memory usage patterns and bad CPU cache utilisation, where you end up touching a lot of data and you end up touching it again and again and again each time after it has been purged from the CPU caches. By the way, memory really doesn't work on a byte level from performance perspective, it works on a cache line level, just think of cache line as being 64 bytes, that's fair enough in most cases (and when it isn't quite true, you get a slog like Pentium 4), but that is a story for another day, and its popular implication, false sharing, which is one of those reasons why software often doesn't scale beyond a handful of cores, and even worse across CPU sockets. But then, diffusely slow software is memory bandwidth constrained, so even though memory mapped mass storage device might help over pagewise swap, it won't exactly rescue it from performance implications. Actually come to think of this, every storage device up to a couple exabytes is "small" in relation to our address space - it's currently not practical due to page table size explosion, but what if upper hierarchy level could contain some shortcuts? What if your normal SATA SSD could be memory mapped too for lower latency of short accesses? Maybe we need to rethink how operating systems could use the address space better, with some hardware help, now that we're well past the 16- and 32-bit system constraints. It's a possibility that letting software mark pages with different expected performance levels and use that to guide swapping decisions might be helpful, but in my personal opinion, it just won't experience much takeup because there would be too much code to revise, and ensuring the correctness of such a thing with very implicit performance effects and no direct correctness effects would be a complete nightmare, so it would risk doing more harm than good. More on this later. A good software development practice is to place data that is likely to be accessed together into the same page using special-purpose allocators or smart allocators. Modern general-purpose memory allocators generally automatically make the assumption that if memory was requested in close proximity by time and also in chunks that have the same size, the chunks are likely to also be used in close proximity by time and should occupy same page. It's already fairly important that developers exploit this assumption to prevent the allocator data structure size explosion, and since allocators take logarithmic time for allocation/deallocation operations depending on their structure size, also prevent gradual slowdown. Another side effect of not exploiting allocation proximity rules, because memory that was allocated in close temporal proximity to each other was not also deallocated in close temporal proximity, is software that looks like it leaks memory, it's called memory fragmentation or allocator fragmentation or address space fragmentation, and this is fairly hard to catch, because on tool based checks the behaviour of the program comes out correct, you know it's doing badly, but there's a million spots that could be the culprit, and usually not alone but in interaction with one another, so what are you gonna do? The only way to fix this really is by a random stroke of accidental genius, usually on a very contrived hunch, and you can't just expect that to happen on a schedule. And here is why i don't think marking pages with swap priority is a good idea, it just adds another similar layer of undebuggable behaviour into the software.

@Mythricia1988

@Vyor NVDIMM / nonvolatile RAM is not the point of my post. As I said in the post, these technologies are not main memory, they're a different layer. There has always been NVRAM available, even just as simple as battery backed SRAM for example. But that's not what this is about. @Siana - By byte addressable, I mean you select a byte to access and the subsystem gives it to you without large overhead. Ordinary RAM is very much byte addressable in that sense. You just don't see it that way because you don't write low level code. In Asm, you can access memory by page and offset registers, which really is just a multiplication to get you the address you want. This is obviously not possible in protected mode (outside of thread-specific stuff if I recall correctly, which I probably don't). But it is a feature exposed by the CPU memory manager. Anyhow, you don't read-erase-write to change a single byte in RAM. You do in Flash - you HAVE TO erase the whole page, even if you just want to change 1 bit. So you have to read the whole page, commit it to the controller memory (usually DDR3 or 4 these days), erase the Flash page which is a slow operation, then you have to write it back. This leads to super slow response times if you are writing data, and it also leads to write amplification and other problems. Byte-addressable storage like Optane (or any number of existing exotic non-volatile storage for that matter) doesn't have this problem, because, well, as it says, it's byte-addressable. You change 1 byte, you write 1 byte. This is the primary reason why Optane is low latency. I agree with what you say though, it's a hard problem to solve. I never claimed otherwise. But to say it's impossible somehow is also not true. We do this all the time in embedded electronics or discrete component electronics. We very much address memory directly byte by byte, address line by address line. It's no different for a modern CPU either for that matter - it too, in the end, addresses memory directly. It has to, because that's the electrical specification of DRAM memory. So clearly it can do this. I don't see why it's impossible or inconceivable that this could be extended to an intermediary type storage. That's why I say it needs platform / hardware level support. It can't just be an abstraction. When you say page managed, you are talking like thousand-mile-high level view of how the hardware works. I mean actual hardware level. This is clearly a job for the CPU on-chip memory manager, not the CPU microcode, nor the instruction set architecture, nor the software. There will of course need to be an outward interface to this memory, and it needs to be presented as different from RAM, because otherwise you have the problem you describe, where nobody knows what data resides on slow or fast memory. Which is a problem we already have anyway, because of cache memory being secretly managed by the CPU and not the programmer (it wasn't always the case). We can make very good educated guesses and make it do what we want *most* of the time, sure. But talk to any programmer about cache misses and you'll obviously know it's not a solved problem. So to avoid that, make it discrete. Make it an option. We survived changes like that in the past, we can survive doing it again. There's lots of different architectures out there other than x86/-64, and many of them have millions of lines commited to them every day, and not all of them handle memory the same way x86/-64 does. And, like I hinted at before, even x86 has a clusterfuck of a memory manager anyway, it's just that most programmers either never see it or don't even know it exists. Even though basically nobody uses it except bootloaders, Real Mode is still there. That doesn't mean you have to use it. This intermediary memory could work the same way. It could be there, but that doesn't mean you have to use it. But if you DO - it can provide great benefits.

You can already natively use storage drives as extra RAM space on Linux, but it's called a Swap Partition, or a Swap File, Swap File is a more better and modern approach to adding additional RAM swap space for your machine, since you can dynamically allocate RAM swap from your storage drive, which is a better alternative to having a Swap Partition which is fixed RAM space at the time of install and cannot be dynamically modified after since it's sections off a partition on your storage drive that is equal to your currently installed RAM modules. For example if your machine at install time has 8GB RAM, it'll section off an additional 8GB or 7.5GB from your storage drive for the Swap partition. Swapfile on the other hand is much easier to configure and quick to setup and can be done anytime at a later date after the OS has been installed. In addition to having a Swapfile there's a Linux kernel feature for Zswap or Zram as it's called, which reduces load on IO for better performance for cached paged files using a virtualized compressed swapfile in memory as alternative to swapfile on disk. Plus there is no need to RAID stripe since it's automatically done by the kernel within those swapfiles and assign their priority in /etc/fstab. You can even use USB sticks as an expandable swap space, at the cost of speed dictated by the USB port itself. It should also be noted that Btrfs formatted partitions DO NOT support Swapfiles on storage which will most definitely lead to system corruption. Info taken can be found on the Arch Linux Wiki : wiki.archlinux.org/index.php/swap So to create a swapfile, just open up your Terminal or whatever and you use the `fallocate` command like so as root, along with how much you wish to allocate for your swapfile, and where to write it to. fallocate -l 512M /swapfile the suffix letter M (Megabytes) is needed to tell the system how much memory you wish to allocate, this can be changed to be G (Gigabytes), or MiB (Mebibytes), or GiB (Gibibytes). So if you wanted 6GB you would do `6G` instead to allocate 6 Gigabytes. Next using the `dd` command very carefully as root, since this can be pretty dangerous if you don't know what you're doing to write zeros to the swapfile so it's completely blank and ready for use; dd if=/dev/zero of=/swapfile bs=1M count=512 So let's break it down here, `if=/dev/zero` is your input write stream, and `of=/swapfile` is your output stream of the created swapfile. The `bs=1M` is the bytes per second it should write at, ie; 1 Megabyte/s a second. Then you have `count=512` the size of your Swapfile. -- Next up you want to make it non-readable to all but the system with `chmod` command. chmod 600 /swapfile after creating the correct swapfile size you wanna do `mkswap` command as root to convert the swapfile to a swap readable space. mkswap /swapfile then finally you can tell the system to mount it by doing the following as root; swapon /swapfile and finally to make it all permanent you need to add it to your `/etc/fstab` like so; /swapfile none swap defaults 0 0 simple as that, and of course if you want to remove it at any stage it's as simple as doing this; swapoff -a rm -f /swapfile and removing any traces of it from `/etc/fstab`

i once saw like 4 gb of ram for about 60 euro and 16gb of ram for about the same price

So is this an example of swapfile-esc application, or is it more like the Readyboost option?

Whats a good motherboard that can support a intel-8700k, GTX 1060, SSD, HArddrive, NZXT kraken x62, a good amount of fans for a s340 elite case, a lightstrip thing, and has Bluetooth

I think you will see the BIGGEST difference. NOT in comparing gig to gig. But, Optaine, will shine in being able to have a zillion gigs of artificial ram. So you test should focus on 16 or 32 gigs of REAL ram. Versus 256 or 512 or 1024 whatever it can go to, of artificial ram. I would be way interested in seeing those results.

Having more swap/pagefile space won't make it any faster if it isn't using it. The system only uses how much page file it needs. You can go make your 10tb hdd a swap file, but it won't make the system any faster.

i was going on the same principle that 2 gigs of RAM will preform faster than 2 k of RAM. A bigger scratch disk will get things done faster. To a point, then it will level out. 32 or 64 gigs is usually that plateau. Unless you are doing video stuff. And after a certain point, it would probably be more economical to do this optaine thing. Well, maybe. I don't know the prices. But I do know that RAM is so expensive now. I just bought 64 ddr4. pricey $$$

Well, this was pretty much a proof-of-concept of that very idea's use in a future workload rather than a direct application of that idea. I suspect a workload that would benefit from that would be difficult to test at this point in time, so the artificial constraints were used to lower that bar to something that could be readily tested today. As he was explaining in the video, it showed more promise of potential use in the future IF developers account for its use, rather than a ready solution to an existing problem today.

Icarus if the memory controller on the Optane module has more storage chips to work with, it can spread out the load across more of them and enable faster response times

You should have done a run with the optane working along side the 16GB or system memory to see if it gives any performance boost. I wonder if some company editing workstations that have maxed out all the RAM slots can see a benefit in rendering times by adding is a load of optane drives on top of their RAM.

Doing the raid right, you could either increase the amount of virtual ram OR the speed of it this way (or both ... but error checking I think is not quite as necessary.) I do wonder if you could get nearly same-as-real-RAM performance with this and, if so, how much it would cost compared to the real RAM solution (particularly against single channel if you were trying to get something cheaper than buying that 2nd stick).

It's certainly likely that they might be price-fixing DRAM. But it is dead certain they are price-fixing NAND to a ridiculous degree and have been for years. The DRAM that's in short supply today is hard to make. It's not super complicated, but it has to tolerate really high clock speeds, so quality is crucial, so not just anyone can make it. NAND... is a different story. NAND is like the most basic thing imaginable. Regular memory cells, laid out in a regular grid, doesn't need to be produced on a super small process, doesn't need to run at gigahertz clock speeds. Has no rare materials involved in its production. AND, the really telling sign, it's in EVERYTHING. Every phone, every computer, every TV, every watch, appliance, most toys, basically anything that has a battery or plugs in has at least one NAND chip for storing persistent stuff. And yet... somehow, it remains more expensive on a per-GB basis than mechanical hard drives which require high-precision high-speed motors, sensitive read heads, rare materials coating the platters and in the components on the control board... they're even talking about putting LASERS in the things and still they're cheaper per-GB than solid state storage? That is some grade-A price-fixing industry-rigging bullshit. And it shouldn't surprise anyone. These exact same companies got busted for price fixing RAM. Then they got busted for price fixing LCDs. The signs were exactly the same too. A component starts getting used in everything, it becomes a commodity and its price drops drastically. When they stopped price-fixing LCDs, 40 inch TVs went from $2000 to $300 in a couple years. We need the same thing for SSDs badly. We should be able to buy a 16TB SSD for $100 easily by now.

We've had dirt cheap lasers in PCs 20 years ago, don't see what the big deal is, it's just a somewhat different, slightly more difficult to manufacture variant of an LED now. I know, these are getting less popular now, but when my last DVD drive burned out, i bought a new one for less than $20, and this was a decade ago now, and when you repair an old game console, you can usually get a new sled with a laser, optics and a number of voice coils for just $4. Price fixing by limiting supply? Possible. How effective is it? I don't know, 500GB SSD for $100... sounds dirt cheap to me, there's a good area of a silicon wafer in this thing, and it is really not that basic, it's slow, but it's analogue multi-level capacitive storage, so the tiniest leak that doesn't hurt DRAM, which is always leaky and needs refresh, basically ruins it. Maybe it could cost half what it does, but i don't find it likely that they can straight up compete with magnetic storage on prices. If it was this basic, then why hasn't a random obsolete semiconductor plant in China started manufacturing NAND? Even if they couldn't sell it abroad because patents or whatever, Chinese citizens and organisations buy billions of domestically produced NAND-equipped devices each year, that rely on imported chips, so any price fixing basically couldn't continue.

NAND manufacturers use the optimum process size for reliability reasons. Reliability plummets with decreasing process size, so there is an effective minimum. The invention of V-NAND allowed Samsung to go back to a larger and significantly more reliable process. Because flash is in everything, and because there are more "things" out there than ever, the demand continues to increase, which should increase costs. This seems to be balanced by improvements in technology. The price had actually been falling until recently. As with DRAM, the market conditions are right for its cost to increase dramatically.

@DustinRodriguez1_0

5 жыл бұрын

Increasing demand only increases price temporarily. Supply increases to meet demand if you're dealing with something as simple and easy to make as NAND flash memory. Once demand is high enough, scale drives the market and the component becomes commoditized. Once something is a commodity its cost drops to almost nothing. We saw this with RAM, and it got price-fixed by Samsung and their friends. They got busted. Then prices fell. We saw this with LCD panels, and they got price-fixed by Samsung and their friends. They got busted. Then prices fell. Now we see it with NAND, its probably being price-fixed by Samsung and their friends. They got investigated. But the investigation got dropped by the president of South Korea. The president of South Korea got busted for taking bribes. The president of Samsung got busted for paying bribes. The investigation remained dropped. Then RAM prices started going up too...

Considering that people feel like throwing out their computer after it's just 1 year, I doubt lifespan of Optane or SSDs are that important, unless I guess you were using them in a server...

if you already have a very modern intel platform and regular sata driuves it'd be a good use of an m.2/NVME port

so from the read/write speeds shown at 2:19, we can conclude that Optane is slower than modern NVME-SSDs (Samsung 960 Pro, any SSD in a new Mac, etc). So if you have a modern SSD in your computer, it will actually be cheaper and faster to let the CPU use your NVME-SSD for memory swap ?

Because if you have a budget of 4GB you will be able to afford this thing and a high end MOBO.

We're talking about a system that doesn't "boot" so much as turn on to "exactly where you last left off". We would still need the ability to "reboot" so long as Microsoft stays in business, naturally, but we're talking storage space approaching ramdisk performance at significantly reduced costs. And if 3DXpoint takes off, then we're looking at a future without hard drives for general consumption, with NAS storage bricks becoming more commonplace for storing/archiving media. One 512GB Optane DC dimm stick would be able to run your entire OS and app needs, and most motherboards have 4 slots... Imagine raiding DIMM slots... Imagine 2 TB storage faster than NVMe that boots as fast as your monitor can turn on... The possibilities...

The moment people are actually buying it consistently Intel will raise the price citing "production shortages".

What you did was just setting up the Optane drive as virtual memory? or was it something else?

How about just to get your pagefile off of your typical storage drives? Not using pagefile for SSD has got to help with longevity, and turning it off for HDDs means better responsiveness and throughput when you need it.
