New Developments In Supercomputing
In November 2014, it was announced that the United States was developing two new supercomputers to exceed China’s Tianhe-2 in its place as world’s fastest supercomputer. The two computers, Sierra and Summit, will each exceed Tianhe-2’s 55 peak petaflops. Summit, the more powerful of the two, will deliver 150300 peak petaflops. On 10 April 2015, US government agencies banned selling chips, from Nvidia to supercomputing centers in China as “acting contrary to the national security … interests of the United States” and Intel Corporation from providing Xeon chips to China due to their use, according to the US, in researching nuclear weapons research to which US export control law bans US companies from contributing “The Department of Commerce refused, saying it was concerned about nuclear research being done with the machine.”
On 29 July 2015, President Obama signed an executive order creating a National Strategic Computing Initiative calling for the accelerated development of an exascale system and funding research into post-semiconductor computing.
In June 2016, Sunway TaihuLight became the No. 1 system with 93 petaflop/s on the Linpack benchmark.
In November 2016, Piz Daint was upgraded, moving it from 8th to 3rd, leaving the US with no systems under the TOP3 for only the 2nd time ever.
As of June 2019, all TOP500 systems deliver a petaflop or more on the High Performance Linpack benchmark, with the entry level to the list now at 1.022 petaflops.

How The Xps 17’s Performance Compares
Other than the XPS 15 and the MacBook Pro, the XPS 17’s main alternatives are big-screen gaming laptops like the ROG Zephyrus S17. To compare the big Dell’s performance against its peers, I matched its benchmark results against those of the Zephyrus, the MacBook Pro, and two more gaming rigs, the Alienware m17 R4 and Razer Blade 15. Admittedly, the XPS 17 is not meant as a gaming laptop, first and foremost, so take the gaming machines’ relative numbers in context.
From a qualitative standpoint, the XPS 17’s performance is superb. Not once did I experience lags or sluggishness with any task I threw at it, although that’s only to be expected at this price. One of our two minor performance complaints with last year’s model was related to noisea high-pitched whine from the basebut that wasn’t a problem with this unit. Nor did the battery discharge while running on AC power, our other complaint when we pushed last year’s XPS 17 to the limit. Some non-gaming laptops have AC power adapters that aren’t sufficient to deliver the peak requirements of the CPU and GPU simultaneously.
The XPS 17 and all of its Windows competitors aced our comprehensive PCMark 10 benchmark, which we use to assess overall system performance for office-centric tasks such as word processing, spreadsheet jockeying, web browsing, and videoconferencing. Any score over 5,000 points indicates outstanding productivity.

Should You Really Go This Large Though
On the negative side, this screen size dictates a bulky machineâone that’s often too big for a briefcase, requiring a special laptop bag, backpack, or roller bag, and too heavy for more than occasional transport between home and office or cubicle and conference room.
The lightest 17-inch laptops, with one major exception, weigh in at just under seven pounds. The heaviest, which are invariably gaming models, tip the scales at a back-breaking 10 pounds or more, and in some cases, that’s not counting two ponderous AC power bricks. Airline tray table? Forget it. More like checked baggage.
Nor should you expect long battery life from a plus-size notebook. These machines are designed to run on AC power most of the time. If yours can endure unplugged for more than four hours, consider yourself lucky.
So, are these tradeoffs too much to suffer merely for a pleasing view? Are luggables just the large-print books of the laptop world?
Noâthey’re also the performance leaders. Their chassis accommodate the most powerful processors and graphics cards, the strongest cooling systems, the most memory, and multiple solid-state drives or hard drives for ample storage. They have plenty of room for all the ports you might need, as well as spacious, near-desktop-class keyboards with full keypads for numeric data entry.
Jumbo laptops aren’t for frequent fliers, but they fill a big niche. Let’s look at what they can do, and what to look for as you shop for one.
Work Or Play: Which Is Your Main Aim
A few 17-inch laptops are general-purpose PCs for people who want an occasionally portable system with a large screen. Most, however, fall into one of two camps with diametrically opposed, but equally hardcore, audiences: mobile workstations, and serious gaming laptops.
Both types can handle what many PC users think of as work: office productivity and email using Word, Excel, Outlook, Chrome, Slack, and so on. But mobile workstations, as seen in our special guide, laugh at such modest apps. Instead, they carry independent software vendor certifications of compatibility and smooth operation with programs for way tougher computing jobs: computer-aided design and advanced 3D modeling and rendering, crunching through huge scientific or engineering datasets, or delving into video editing and the creation of worlds for virtual reality. And they rely on state-of-the-art CPU and GPU power to do so.
With the exception that CPU muscle is a little less important while GPU strength is paramount, much the same applies to gaming rigs . They’re designed to play the latest and greatest titles at high speedsâat least 60 frames per second, double the rate recognized as providing minimally smooth gameplayâwith all the visual details and eye candy turned up to 11. Onscreen stuttering or tearing just won’t cut it. Lag can be fatal during a fragfest.

Why Not Use A Ruler
Can you use a ruler to measure your laptop size? Yes, you can, but a ruler is not flexible, so it will be a more difficult task. Also, bear in mind that most laptops have rounded edges, and you can easily compensate for this with a tape measure but not with a solid ruler.
Of course, if you do not have access to a tape measure, then using a ruler is the next best thing. Nevertheless, you need to be aware that the measurements you take are less likely to be as accurate as with a tape measure.
What To Look For In The Display Panel
For most 17-inch laptops, you will get an In-plane switching or Indium gallium oxide panel that provides the best screen contrast and sharpness. This, in particular, comes with intense benefits for gaming laptops. These panels give you the best viewing angles for the best display experience. Now, thats being said, the type of panel you need depends on your purpose.
Many a gamer is likely to pick a 4k resolution screen that requires a GPU like Nvidia GeForce RTX 2070 or 2080 that ensures fast graphics processing. A content creator might also opt for a 4K screen to get the desired output with the best choice of sRGB and Adobe RGB print.
The same can be said about the refresh rates, which are likely to give you a smooth visual. If you are a gamer or video editor, you do want a display with refresh rates above the standard 60Hz.
For more graphic intense games, one could look for a display panel that loads a refresh rate of 240Hz. On the last note, do ensure the screen display panel supports G-sync technology for smoother appearances.

Insist On Good Image Quality For Your Laptop With An Eizo Display
Recently some high-end laptop computers, such as the Sony VAIO F, are insisting on good display quality for their LCDs. However, a typical laptop’s built-in LCD does not have as good image quality as a stand-alone LCD. This is only natural since the costs allowed for display quality are completely different for an LCD incorporated into the PC as one of its parts and a specialized LCD.
However, by using an EIZO wide-screen LCD a laptop user can still fully enjoy such benefits of a stand-alone high-quality LCD as excellent color reproduction, a wide viewing angle, more even display and a wealth of items that can be adjusted to improve image quality. This is a crucial point for people who use their computer for photographs and videos in particular.
EIZO’s wide-screen LCDs emphasize color reproduction, and the coloration in sRGB mode has a high degree of accuracy. The standard color gamut used in PC environments and Internet content is sRGB, so you need have no worries about viewing or editing videos and photographs. They can also display images on web pages, such as products in online shops or goods for sale in online auctions, in colors that are very close to the real thing.
How To Measure Laptop Screen Size
To physically measure the size of your laptop screen, it is better to use a tape measure than it is to use a ruler. This is because the standard measurement for a laptop screen is in inches. Therefore, if you live in a country that uses the metric system, you will need to convert the metric measurements into inches. Again, there are online converters for this.
You will need to measure your laptop screen diagonally, so you will need to choose a starting point. You can start at the bottom left of your laptop screen or the bottom right. It doesnt matter which of these you choose.
Please bear in mind that you just want to measure the size of the screen and not the enclosure that keeps it in place. So begin the measuring process at the corner where your screen starts to be visible outside the enclosure.
Now you need to extend your measuring tape in a straight line diagonally to the opposite corner of your laptop screen. Therefore, if you began in the bottom left corner, you need to extend to the top right corner and if you started in the bottom right corner, then extend to the top left corner.
If you wonder why you need to take a diagonal measurement, the blame lies with the screen and laptop manufacturers. A diagonal measurement will produce a larger screen measurement, which is a good selling point.

Why Do You Need A 17
Anytime the image of a 17-inch laptop comes to mind, one tends to connect it with a machine thats bulky to carry. This entails the need for unique laptop bags or backpacks when taking such laptops on a trip. However, this may not be the case with modern laptops like LG Gram 17, which only weighs 3 pounds.
Thats aside there is no question that there are laptop models that weigh up to 10 pounds. Examples of these laptops are the gaming models due to their heavy demands of high-quality games on display, processor, GPU, and display. Buying a 17-inch laptop doesnt mean you get an extended battery capacity. You did be lucky if you get a model that stands running for 4 hours without power.
