Breakthrough by IBM May Bring Us Exascale Supercomputers

Diposting oleh Admin on Rabu, 17 Oktober 2012

If you are one of the people out there that doesn't think that a supercomputer seems good enough, then you probably work at IBM. Researchers at IBM have just made a breakthrough in using light pulses to help accelerate the transfer of data between chips. If this works out like the people at IBM think it will, then it could quite possibly increase supercomputer performance by more than a thousand times.

This technology, dubbed CMOS Integrated Silicon Nanophotonics (I feel smarter already), integrates optical modules as well as electrical modules on a single piece of silicon. This allows electrical signals created at the transistor level to be transformed into light pulses, seemingly allowing chips to communicate faster according to IBM silicon photonics research scientist Will Green.

IBM believes that this new technology will lead to massive advances in supercomputer power. The fastest supercomputers we have around today max out at nearly 2 petaflops which, for us lay people, registers into two thousand trillion calculations per second. The photonics technology could increase this number to a staggering trillion million calculations per second. Yeah, a MILLION TRILLION calculations per second, otherwise known as an exaflop. This would help IBM achieve their goal of building an exascale computer software companies by the year 2020.

According to Green, "In an exascale system, interconnects have to be able to push exabytes per second across the computer network. This is an interesting milestone for system builders who are looking at building exascale systems in 10 years."

The possibility of integrating multiple photonics modules onto a single substrate or onto a motherboard is here, according to Green. Newer supercomputers already use optical technology for chips in order to communicate. However, this usually occurs at the rack level and mostly over a single wavelength. This breakthrough will allow optical communication simultaneously at multiple wavelengths.

The good thing about this technology is that it can be manufactured on a standard chip production line. Another benefit is that it also needs no special tools, making it extremely cost-effective. The current demonstration used a 130-nanometer CMOS manufacturing node. However, IBM plans on pursuing integration into "deeply scaled sub-100 nanometer CMOS processes," according to Green.

The technology aims to replace copper wires. As you know, copper wires are widely used today for data transfer between chips. Optics can get a speed increase for distances as short as a few centimeters to as long as a few miles and even consumes less power. Eventually, IBM hopes to use optics for on-chip communication between transistors as well. According to Green, "There is a vision for the chip level, but that is not what we are claiming today."

Microsoft's IE9 Strategy Fails to Produce Results

Internet Explorer 9As the rise of other browsers, like Google Chrome, begin to show, so does the demise of others, namely Internet Explorer. The web browser, designed by Microsoft, continued to lose members last month, losing the largest number of users since December 2010.

During September, Internet Explorer lost nine-tenths of a percentage point of share, dropping to 54.4%, a new record low for the browser. The drop experienced last month was the seventh straight decline and the largest decline since December of last year where Internet Explorer fell by 1.1 points. Causing the decrease was, of course, Google Chrome, which saw shares increase by seven-tenths of a point. Adding to the decline was Apple's Safari browser, which saw an increase of four-tenths of a percentage point.

Chrome ended the month with a 16.2% share with Safari accounting for 5% of all browsers used worldwide. Microsoft, on the other hand, focused on looking at the brighter side by plugging the success of Internet Explorer 9 on Windows 7. Head of Internet Explorer's Marketing Roger Capriotti used data from Net Applications to highlight the gains of IE9 by pointing out that the browser version owned 21% global share of browsers running on Windows 7.

Internet Explorer 9 is the second-most popular internet browser on Windows 7 with a 21% compared to Internet Explorer 8's leading 31.6%. Firefox 6 and Chrome 13 came in third and fourth place, respectively, with 13.9% and 13.1%. Unfortunately, Microsoft hasn't outlined an alternate strategy for stopping IE defections. While the focus on Internet Explorer 9 may pay off in the long run, it has failed to slow down the number of defectors heading to Safari, Chrome or Firefox. Since its debut, Microsoft has lost 4 percentage points of share with Internet Explorer 9.

New Finger and Stylus Gestures Could Be Coming to Windows 8

Diposting oleh Admin

Windows 8A lot of people are excited about the upcoming operating system from Microsoft known, as of right now, as Windows 8. Windows 8, or whatever it is named upon release, is the highly anticipated successor to the the immensely popular Windows 7 operating system currently out from Microsoft. However, some new developments are leaking their way onto the internet, including the fact that Microsoft has unveiled several patent filings that are pointing to new finger and stylus gestures that could be incorporated into Windows tablets.

These patent filings were actually filed back in 2010 but Microsoft just published them last week. These new patents show that Microsoft believes finger and stylus gestures can work not only separately but together as well in order to offer a user-friendly means of input on new touch screen devices. This new method that would recognize both methods of input would recognize the first method as your finger and the second as your stylus. Using both your finger and your stylus could then create a variety of gestures, a lot of which seem to be geared more toward image editing though could be put to other uses as well.

For example, a copy gesture would allow you to tap on an object with your finger and then move it around with your stylus. A cut gesture would allow you to split an object in half using fingers, a stylus or both at the same time. A brush gesture would assist you in removing part of an image and then storing it somewhere else on the screen. A staple gesture may be used to stack multiple objects or images on top of each other and a stamp gesture would create duplicates of whatever you wanted.

The upcoming Windows 8 operating system for tablets was unveiled by Microsoft at the D9 Conference back in June. Microsoft is expected to release more information and details about the OS at the upcoming Build Conference in September, with a beta possibly ready for developers to test out at that time as well.

Sometimes you only need computer technology for a short time, perhaps to augment your business's computing capacity during peak business seasons. Purchasing technology to meet such a temporary need involves taking on unnecessary expenditures, and inevitably leaves you or your business with a lot of superfluous technology after the need is fulfilled. So renting computer technology makes perfect sense for such ephemeral needs.

Not only can procure any computer rental you might need, but they can also configure temporary solutions and technology packages that include computer peripherals as well.

What are Computer Peripheral Rentals?

Computer Peripheral Rentals From Rentacomputer.comComputer peripherals are any accessory items that you might want or need with your computer rental, whether you are renting a laptop, desktop, or tablet computer. Having the right accessory items with your rental can be crucial, and it is often the case that renters do not already have many of the accessories they might need to make their rental function in the capacity that they need it to.

Gigabit Switches

If your you Computer Rental consists of several or more computers that will be operated simultaneously by various users, then you might very well need a gigabit switch. This will allow you to connect your laptop rentals to one LAN source, which is invaluable if you need to have multiple users simultaneously connecting to the web. Our Tech Travel Agents typically recommend either an 8 Port 100/1000 Gigabit Switch or a 24 Port 100/1000 Gigabit Switch, depending on how many computers you are renting.

Wireless Routers

Wireless Routers are also a very important peripheral if you need to wirelessly connect your Computer Rental. These especially become valuable when you are putting together interactive trade show booths, or require event planners and maintenance personnel to stay connected via laptops or tablet computers. Wireless routers are also invaluable if you are setting up a temporary office. Our agents usually recommend a Cisco/Linksys 4 Port Wireless Router.

Computer Cable Locks

Computer Cable Lock RentalsNetwork Security can often be an issue, especially if you are setting up a booth or kiosk with your computer rentals, where a lot of traffic will be passing by. You can ease your worries about the security of your rentals by adding cable locks to your rental configuration, so that you can lock down each unit and protect against theft.

Conference Phones

Conference Phone RentalsA very handy accessory to have when you need to keep in touch with multiple collaborators is a conference phone, whereby you can speak with the people you need to speak with all at once and expedite project logistics. Our Tech Travel Agents recommend getting a Polycom Soundstation for your conference speakerphone rental.

Wireless Presentation Mouse & Remotes

If you are getting a Laptop Rental for presentation purposes, then you should also consider getting a wireless mouse or remote added to your rental configuration. With these accessories you can have a lot more freedom while giving your presentation, instead of being tied down to wherever your computer is stationed.
