OS Limitations of Vulkan Multi-GPU Support

Subject: Graphics Cards | March 21, 2017 - 07:47 PM |
Tagged: windows 10, vulkan, sli, multi-gpu, crossfire

Update (March 22nd @ 3:50pm EDT): And the Khronos Group has just responded to my follow-up questions. LDA has existed since Windows Vista, at the time for assisting with SLI and Crossfire support. Its implementation has changed in Windows 10, but that's not really relevant for Vulkan's multi-GPU support. To prove this, they showed LDA referenced in a Windows 8.1 MSDN post.

In short:

Vulkan's multi-GPU extensions can be used on Windows 7 and Windows 8.x. The exact process will vary from OS to OS, but the GPU vendor can implement these extensions if they choose, and LDA mode isn't exclusive to Windows 10.

 

Update (March 21st @ 11:55pm EDT): I came across a Microsoft Support page that discusses issues with LDA in Windows 7, so it seems like that functionality isn't limited to WDDM 2.0 and Windows 10. (Why have a support page otherwise?) Previously, I looked up an MSDN article that had it listed as a WDDM 2.0 feature, so I figured DSOGaming's assertion that it was introduced with WDDM 2.0 was correct.

As such, LDA might not require a GPU vendor's implementation at all. It'll probably be more clear when the Khronos Group responds to my earlier request, though.

That said, we're arguing over how much a GPU vendor needs to implement; either way, it will be possible to use the multi-GPU extensions in Windows 7 and Windows 8.x if the driver supports it.

Update (March 21st @ 7:30pm EDT): The Khronos Group has just released their statement. It's still a bit unclear, and I've submit another request for clarification.

Specifically, the third statement:

If an implementation on Windows does decide to use LDA mode, it is NOT tied to Windows 10. LDA mode has been available on many versions of Windows, including Windows 7 and 8.X.

... doesn't elaborate what is required for LDA mode on Windows outside of 10. (It could be Microsoft-supported, vendor-supported, or something else entirely.) I'll update again when that information is available. For now, it seems like the table, below, should actually look something like this:

  Implicit Multi-GPU
(LDA Implicit)
Explicit Multi-GPU
(LDA Explicit)
Unlinked Multi-GPU
(MDA)
Windows 7 Requires GPU Vendor
LDA Implementation?

(Or Equivalent)

(Or Equivalent)
Windows 10
macOS Apple doesn't allow the Vulkan API to ship in graphics drivers.
At all.
Linux / etc.

... but we will update, again, should this be inaccurate.

Update (March 20th @ 3:50pm EDT): The Khronos Group has just responded that the other posts are incorrect. They haven't yet confirmed whether this post (which separates "device groups" from the more general "multi-GPU in Vulkan") is correct, though, because they're preparing an official statement. We'll update when we have more info.

Original Post Below (March 19th @ 9:36pm EDT)

A couple of days ago, some sites have noticed a bullet point that claims Windows-based GPU drivers will need WDDM in “linked display adapter” mode for “Native multi-GPU support for NVIDIA SLI and AMD Crossfire platforms” on Vulkan. This note came from an official slide deck by the Khronos Group, which was published during the recent Game Developers Conference, GDC 2017. The concern is that “linked display adapter” mode is a part of WDDM 2.0, which is exclusive to Windows 10.

This is being interpreted as “Vulkan does not support multi-GPU under Windows 7 or 8.x”.

khronos-2017-vulkan-alt-logo.png

I reached out to the Khronos Group for clarification, but I’m fairly sure I know what this does (and doesn’t) mean. Rather than starting with a written out explanation in prose, I will summarize it into a table, below, outlining what is possible on each platform. I will then elaborate below that.

  Implicit Multi-GPU
(LDA Implicit)
Explicit Multi-GPU
(LDA Explicit)
Unlinked Multi-GPU
(MDA)
Windows 7    
Windows 8.1    
Windows 10
macOS Apple doesn't allow the Vulkan API to ship in graphics drivers.
At all.
Linux / etc.

So the good news is that it’s possible for a game developer to support multi-GPU (through what DirectX 12 would call MDA) on Windows 7 and Windows 8.x; the bad news is that no-one might bother with the heavy lifting. Linked display adapters allow the developer to assume that all GPUs are roughly the same performance, have the same amount of usable memory, and can be accessed through a single driver interface. On top of these assumptions, device groups also hide some annoying and tedious work inside the graphics driver, like producing a texture on one graphics card and quickly giving it to another GPU for rendering.

Basically, if the developer will go through the trouble of supporting AMD + NVIDIA or discrete GPU + integrated GPU systems, then they can support Windows 7 / 8.x in multi-GPU as well. Otherwise? Your extra GPUs will be sitting out unless you switch to DirectX 11 or OpenGL (or you use it for video encoding or something else outside the game).

On the other hand, this limitation might pressure some developers to support unlinked multi-GPU configurations. There are some interesting possibilities, including post-processing, GPGPU tasks like AI visibility and physics, and so forth, which might be ignored in titles whose developers were seduced by the simplicity of device groups. On the whole, device groups was apparently a high-priority request by game developers, and its inclusion will lead to more multi-GPU content. Developers who can justify doing it themselves, though, now have another reason to bother re-inventing a few wheels.

Or... you could just use Linux. That works, too.

Again, we are still waiting on the Khronos Group to confirm this story. See the latest update, above.

Intel Officially Kicks Off Optane Launch with SSD DC P4800X

Tagged: XPoint, SSD DC P4800X, Optane Memory, Optane, Intel, client, 750GB, 3D XPoint, 375GB, 1.5TB

Intel brought us out to their Folsom campus last week for some in-depth product briefings. Much of our briefing is still under embargo, but the portion that officially lifts this morning is the SSD DC P4800X:

Intel_SSD_4800_FlatFront_OnWhite_RGB_Small.jpg

optane-4.png

optane-9.png

MSRP for the 375GB model is estimated at $1520 ($4/GB), which is rather spendy, but given that the product has shown it can effectively displace RAM in servers, we should be comparing the cost/GB with DRAM and not NAND. It should also be noted this is also nearly half the cost/GB of the X25-M at its launch. Capacities will go all the way up to 1.5TB, and U.2 form factor versions are also on the way.

For those wanting a bit more technical info, the P4800X uses a 7-channel controller, with the 375GB model having 4 dies per channel (28 total). Overprovisioning does not do for Optane what it did for NAND flash, as XPoint can be rewritten at the byte level and does not need to be programmed in (KB) pages and erased in larger (MB) blocks. The only extra space on Optane SSDs is for ECC, firmware, and a small spare area to map out any failed cells.

Those with a keen eye (and calculator) might have noted that the early TBW values only put the P4800X at 30 DWPD for a 3-year period. At the event, Intel confirmed that they anticipate the P4800X to qualify at that same 30 DWPD for a 5-year period by the time volume shipment occurs.

Is 240 Hertz SWIFT enough for you? The new ASUS ROG gaming monitor

Tagged: tn monitor, SWIFT PG258Q, gsync, ASUS ROG, 1080p

As we wait for connectivity and GPU horsepower to catch up to the new technology available in monitors, those who are upgrading face a choice.  If you want incredibly high refresh rates then you have to sacrifice resolution, whereas if 4K is your need then you will have to be satisfied with lower refresh rate ranges.  The ASUS ROG SWIFT PG258Q is one of the former, offering 1080p resolution but with G-SYNC capable of a refresh rate reaching 240Hz.  That extremely high refresh rate also requires the use of a TN panel, so if you prefer 4k IPS then this display is not the one you are looking for. 

Kitguru provides a full review of the monitor here, including a look at the new style of asymmetrical ROG stand which can tilt farther than you might think at first glance.

"Gaming monitors are clearly going through a bit of a growth spurt, and ASUS is a company particularly focusing on this area. The ROG SWIFT PG258Q is a 24.5in screen with a whopping 240Hz top refresh and NVIDIA G-Sync, plus a host of other features specifically tailored for serious gamers."

A new start

Qualcomm is finally ready to show the world how the Snapdragon 835 Mobile Platform performs. After months of teases and previews, including a the reveal that it was the first processor built on Samsung’s 10nm process technology and a mostly in-depth look at the architectural changes to the CPU and GPU portions of the SoC, the company let a handful of media get some hands-on time with development reference platform and run some numbers.

To frame the discussion as best I can, I am going to include some sections from my technology overview. This should give some idea of what to expect from Snapdragon 835 and what areas Qualcomm sees providing the widest variation from previous SD 820/821 product.

Qualcomm frames the story around the Snapdragon 835 processor with what they call the “five pillars” – five different aspects of mobile processor design that they have addressed with updates and technologies. Qualcomm lists them as battery life (efficiency), immersion (performance), capture, connectivity, and security.

slides1-6.jpg

Starting where they start, on battery life and efficiency, the SD 835 has a unique focus that might surprise many. Rather than talking up the improvements in performance of the new processor cores, or the power of the new Adreno GPU, Qualcomm is firmly planted on looking at Snapdragon through the lens of battery life. Snapdragon 835 uses half of the power of Snapdragon 801.

slides2-11.jpg

Since we already knew that the Snapdragon 835 was going to be built on the 10nm process from Samsung, the first such high performance part to do so, I was surprised to learn that Qualcomm doesn’t attribute much of the power efficiency improvements to the move from 14nm to 10nm. It makes sense – most in the industry see this transition as modest in comparison to what we’ll see at 7nm. Unlike the move from 28nm to 14/16nm for discrete GPUs, where the process technology was a huge reason for the dramatic power drop we saw, the Snapdragon 835 changes come from a combination of advancements in the power management system and offloading of work from the primary CPU cores to other processors like the GPU and DSP. The more a workload takes advantage of heterogeneous computing systems, the more it benefits from Qualcomm technology as opposed to process technology.

Introduction: A Hybrid Approach

The Hex 2.0 from Phononic is not your typical CPU cooler. It functions as both a thermoelectric cooler (TEC) - which you may also know as a Peltier cooler - and as a standard heatsink/fan, depending on CPU load. It offers a small footprint for placement in all but the lowest-profile systems, yet it boasts cooling potential beyond other coolers of its size. Yes, it is expensive, but this is a far more complex device than a standard air or even all-in-one liquid cooler - and obviously much smaller than even the most compact AiO liquid coolers.

DSC_0758.jpg

“The HEX 2.0 combines a proprietary state-of-the-art high performance thermoelectric module with an innovative heat exchanger. The small form factor CPU cooler pioneers a new category of cooling technology. The compact design comfortably fits in small chassis, including mini-ITX cases, while delivering cooling capacity beyond that of much larger coolers.”

Even though it does not always need to function as such, the Hex 2.0 is a thermoelectric cooling device, and that alone makes it interesting from a PC hardware enthusiast point of view (at least mine, anyway). The 'active-passive' approach taken by Phononic with the Hex 2.0 allows for greater performance potential that would otherwise be possible from a smaller TEC device, though our testing will of course reveal how effective it is in actual use.

PhononicHex20_Fig1.png

HEX 2.0 features an Active-Passive design (Credit: Phononic)

The goal for the HEX 2.0 CPU cooler was to provide similar cooling performance to all-in-one (AIO) liquid coolers or the very largest fan-heat sinks in a package that could fit into the smallest PC form factors (like miniITX). The active-passive design is what makes this possible. By splitting the CPU heat into two paths, as shown in Figure 1 (Ed. the above image), the thermoelectric device can be sized at an optimal point where it can provide the most benefit for lowering CPU temperature without having to be large enough to pump the entire CPU thermal load. We also designed electronic controls to turn off the thermoelectric heat pump at times of low CPU load, making for an energy efficient cooler that provides adequate cooling with zero power draw at low CPU loads. However, when the CPU is stressed and the CPU heat load increases, the electronic controls energize the thermoelectric heat pump, lowering the temperature of the passive base plate and the CPU itself. The active-passive design has one further benefit – when used in conjunction with the electronic controls, this design virtually eliminates the risk of condensation for the HEX 2.0.

The Seagate Barracuda Pro 10TB Enterprise HDD won't give you the fastest access to your data, but if you have a large amount of storage in a reliable format it is worth looking at this review.  The MSRP of $444.45USD is much lower than you would pay for 10TB of SSD storage, though you might be able to set up several smaller disks in a Drobo or similar device for a similar price.  The MTBF is 2.5 million hours, the endurance rating is 550TB per year and there is a 5 year warranty so even with heavy usage you should be able to depend on this drive for quite a long time.  You can drop by NikKTech to see how it performs.

New "Fabric" for ARM

It is not much of a stretch to say that ARM has had a pretty impressive run for the past 10 years since we started paying attention to the company from a consumer point of view.  It took 22 years for ARM to power 50 billion chips that had been shipped.  It took another 4 years to hit the next 50 billion.  Now ARM expects to ship around 100 billion chips in the next four years.
arm_01.png
 
Last year we saw the introduction of multiple technologies from ARM in the shape of the latest Cortex-A CPUs and a new generation of Mali GPUs.  ARM has been near the forefront of applying their designs to the latest, cutting edge process technologies offered by Samsung and TSMC.  This change of pace has been refreshing considering that a few years ago they would announce a new architecture and expect to see it in new phones and devices about 3 years from that point.  Intel attempted a concerted push into mobile and ARM responded by tightening up their portfolio and aggressively pushing release dates.
 
This year appears no different for ARM as we expect new technologies to be announced again later this year that will update their offerings as well as process technology partnerships with the major pure-play foundries.  The first glimpse of what we can expect is ARM's announcement today of their DynamIQ technology.

DynamIQ can be viewed as a portfolio of technologies that will power the next generation of ARM CPUs, GPUs, and potentially accelerators.  This encompasses power delivery, power control, connectivity, and topologies.

Ultimate Topre

There are cars that get you from point A to point B, and then there are luxurious grand touring cars which will get you there with power, comfort, and style - for a price. Based on the cost alone ($269.99 MSRP!) it seems like a safe bet to say that the REALFORCE RGB keyboard will be a similarly premium experience. Let’s take a look!

DSC_0965.jpg

There is as much personal taste at issue when considering a keyboard (or dream car!) as almost any other factor, and regardless of build quality or performance a keyboard is probably not going to work out for you if it doesn’t feel right. Mechanical keyboards are obviously quite popular, and more companies than ever offer their own models, many using Cherry MX key switches (or generic ‘equivalents’ - which vary in quality). Topre keys are different, as they are a capacitive key with a rubber dome and metal spring, and have a very smooth, fast feel to them - not clicky at all.

img_keyswitch.png

“Topre capacitive key switches are a patented hybrid between a mechanical spring based switch, a rubber dome switch, and a capacitive sensor which, combined, provide tactility, comfort, and excellent durability. The unique electrostatic design of Topre switches requires no physical mechanical coupling and therefore key switch bounce/chatter is eliminated.”

A call to ARM in the server room

As we mentioned last week, Qualcomm's new Centriq 2400 Platform will run Microsoft server operating systems on ARM chips, however there are those who believe it is already too late for that to save Microsoft's hold on the data centre.  A few years ago ARM started work on developing what they called Server Base System Architecture, essentially creating a standardized way in which any OS can communicate effectively with an ARM chip, the same sort of standardization which originally won the server room for x86 based chips.  With ARM's DynamIQ Technology, which Josh discusses in depth, just around the corner their hardware is also becoming more attractive.  Pop by The Register for more details on this possible industry sea change.

"Cutting to the heart of it, it doesn't actually matter if Microsoft releases Windows Server for ARM. Windows isn't the future and even Microsoft knows it.

Overview

If you look at the current 2-in-1 notebook market, it is clear that the single greatest influence is the Lenovo Yoga. Despite initial efforts to differentiate convertible Notebook-tablet designs, newly released machines such as the HP Spectre x360 series and the Dell XPS 13" 2-in-1 make it clear that the 360-degree "Yoga-style" hinge is the preferred method.

DSC02488.JPG

Today, we are looking at a unique application on the 360-degree hinge, the Lenovo Yoga Book. Will this new take on the 2-in-1 concept be so influential?

The Lenovo Yoga Book is 10.1" tablet that aims to find a unique way to implement a stylus on a modern touch device. The device itself is a super thin clamshell-style design, featuring an LCD on one side of the device, and a large touch-sensitive area on the opposing side.

lenovo-yoga-book-feature-notetaking-android-full-width.jpg

This large touch area serves two purposes. Primarily, it acts as a surface for the included stylus that Lenovo is calling the Real Pen. Using the Real Pen, users can do thing such as sketch in Adobe Photoshop and Illustrator or takes notes in an application such as Microsoft OneNote.

The Real Pen has more tricks up its sleeve than just a normal stylus. It can be converted from a pen with a Stylus tip on it to a full ballpoint pen. When paired with the "Create Pad" included with the Yoga Book, you can write on top of a piece of actual paper using the ballpoint pen, and still have the device pick up on what you are drawing.

That's not ominous; so called crimeware installed in 10 industrial plants

This story at The Register raises more than a few concerns, the first of which being that Dragos, the industrial cybersecurity firm which detected the infection called it crimeware.  This is a lovely term for the media to try to explain why computer security is important but carries little valuable information for those wondering exactly this breach entails.  We are all well aware that malware and viruses are used for criminal purposes; not for the benefit of the users who get infected.

It gets better, the infected code was first detected in 2013 and was flagged a false positive.  This infected software has been installed on the Siemens programmable logic controllers of at least 10 industrial plants and in some cases for at least four years.  The insecurity of Internet of Big Things is much scarier than the issues with the IoT, a hacked camera can ruin a person or families day, a hacked power grid has ruined the day of entire countries.

"The cyber-nasty is packaged as software to be installed on Siemens programmable logic controllers (PLC), we're told. At least 10 industrial plants – seven in the US – were found running the infected software, a study by industrial cybersecurity firm Dragos claims."

A long time ago on a website far far away, a brave group of Frogs embarked on a long journey of fun and well ... virtual murderation.   In April of 2003, back when UT2k4 was shiny and new and not retro-gaming the Fragging Frogs held their first live event, a tournament to crown one of us the king of Unreal Tournament.  Since then the gang have been hosting drop-in games every week in a come as you are format and every once and a while Lenny and the crew put together a VLAN party.

FraggingFrogs.jpg

The time has come again to announce another official Fragging Frogs VLAN, this one kicking off at 10AM EDT on Saturday April 8th and going as long as there is still someone gaming.  The previous VLAN saw over 90 people join in at one time or another, with an average of over 50 people active on TeamSpeak and in games.  No matter what type of game you are looking to play, there will be a group you can hook up with to play together or against!

As is tradition, there will be an undisclosed amount of prizes given away at the event but you will have to be on Teamspeak in order to qualify to win.  These prizes are supplied by hardware manufactures, software developers and even from the closets of certain reviewers here at PC Perspective.  You could end up with your own Joshtekk memorabilia!

Post to the official thread to let Lenny and the gang know you plan to attend, especially if you are not yet a forum member as the thread will let you know what you need to do to be eligible to win as well as how to connect to the TeamSpeak server and what patches and mods you should set up.  The list of games people plan on playing has hit 20, if you have one you want to play that is not on the list then make sure to comment in the thread.

You may have seen a similar project in the past, if not this might be something you should check out.  If you have seen it, the process has matured somewhat and the quality of the imaging has improved.  In addition to the Kinect and a decent PC, you will need to install the The Kinect SDK and Kinect Explorer, along with Reconstruct Me, AutoDesk 123D Catch  and Skanect.  Drop by Techware Labs to read through the setup instructions and see if this project catches your imagination, or if there are updates to the process your own Kinect scanner might benefit from.

"HyperX's Alloy FPS keyboard delivers a no-nonsense typing experience with Cherry MX switches. We put this pared-down mechanical keyboard under our fingers to see whether HyperX struck the right balance of solidity and simplicity."

Lexar Announces Durable JumpDrives with USB 3.1

A new line of USB flash drives has been announced by Lexar, which focuses on both durability and USB 3.1 support (compatible with USB 2.0 and USB 3.0). From the technical side, the Lexar JumpDrive Tough drives can read up to 150 MB/s and write up to 60 MB/s, which is obviously nowhere near SSD speed, but reasonably fast for the typical cases that you would use a thumb drive.

As for its robustness, Lexar claims that the JumpDrive Tough will operate normally between -13F and 300F, which is just shy of the bake cookies temperature. It is also water resistant up to 98 feet.

The Lexar JumpDrive Tough will be available in 32GB, 64GB, and 128GB models for $19.99, $34.99, and $59.99, respectively. While I don’t normally consider manufacturer returns for something like this, Lexar is backing this purchase with a 3-year limited warranty, which gives some legal teeth to their claims (if anyone takes them up on it). They are available now.

Is your Joy-Con joyless? The fix is in

The Nintendo Switch seems to be rather popular around these parts but it would seem that not all is wonderful in the land of Zelda.  There have been a slew of reports that the Joy-Cons which Nintendo shipped initially have wireless connectivity issues which interfered with users abilities to use them.  Some enterprising minds cracked the controller open and added a wire to enhance the range and reliability of the Joy-Con's connection.  Ars Technica reports that Nintendo is now offering a fix to customers who are experiencing this issue, they will pay for the shipping back and forth to the repair depot and at least in one case the turnaround was five days.  The fix is a piece of metal-coated conductive foam which should allow you to enjoy your new toy; Nintendo have modified the new models they are shipping to ensure new customers do not run into this problem.

"Opening up the fixed controller showed that Nintendo didn't have to do much to correct the connection issue. The only apparent difference is a small piece of black foam sitting on top of the corner of the controller board that houses the Bluetooth antenna trace."
