The New Fujitsu Supercomputer Processing
The new supercomputer Fujitsu 23.2 petaflops of processing. The petaflops are just as supercomputers used in the acronym comes from Floating Point Operations Per Second or it means the number of operations you can perform that computer. So last week the company in cooperation with the Fujitsu Research Laboratory reported that the supercomputer Reiker K is the first in the list of top 500 fastest computers and powerful in the world.
This broke his own record label processing from the operations or 10 quadrillion calculations per second. Today the company announced a new supercomputer that is able to break the same record again this is referred to as PRIMEHPC FX10. The exact brand supercomputer was 10.51 K arrived but the new computer petaflops PRIMEHPC gets called at least theoretically reach up to 23.2 petaflops of processing.
So the new computer just is not in the list of world’s fastest supercomputers because first of all must pass through a official benchmark used in all computers that are there. So if the new model at least get to have a greater than 10.51 petaflops processing and be the first listing does not achieve more than what the company claims that this gets. Fujitsu and still found that the manufacturer intends to begin marketing units K has 854 racks and uses more than 88,000 different processors also during this year.
For its part, the sales start PRIMEHPC 1024 FX10 has racks and more than 98,000 processors will happen in January next year and the company plans to sell fifty of them over the next three years. Next to the manufacturer FX10 PRIMEHPC Fujitsu also launched a new processor responsible for the incredible power that it presents. Dubbed IXfx Sparc64 it has 16 different cores with up to 236 gigaflops capabilities and operates at 1.86 GHz clock.
For its part also in the world of super processing company to create the first supercomputer solid state memory, and researchers at the University of California announced the planned construction of the first supercomputer capable of storing files via solid memories. The name of the supercomputer is Gordon and the SSD memory used for storing data, which will certainly not few.
In laptops, it’s almost total domination of the SSD memory but this is the first time it is placed into a supercomputer. Which prevented its use was short-lived in a common SSD are supported 3,000 cycles of records. The supercomputer was born through an award of $ 20 million from the National Science Foundation directed to the university. The forecast for the start of operation of Gordon is January 2012.

Samsung Series 5 Ultra Review
Samsung released yesterday in South Korea ultrabooks a new line, called Ultra Series 5. They continue with the same slim design of the Series 9 and Series 7 Cronos but one of his models is a big difference that is not common in laptops of this type, so the model in question presents an optical reader. There will be two main models of fourteen-inch and thirteen inches.
The 14 inch is 20.9 millimeters thick and weighs 1.8 kilograms and a storage capacity Solid State Drive disk from 500 GB to 1 TB. To complete such equipment placed Samsung optical drive, video card AMD Radeon 7550M Ethernet and HDMI and outputs. Meanwhile the 13 inch is 14.5 mm and a limited capacity to a solid state drive up to 500 GB. Even though this model does not present the two outputs optical drive present in his older brother are also present in the smaller model.
The first model will be sold for a price equivalent to $ 1,345 and the second will be in South Korean stores for a price of $ 1,300 according to the report of the company. Both models will be launched this month in the host country of Samsung. In spite of the Series 5 ultrabooks be termed by the company and be sanctioned by Intel who was the creator of these laptops specifications fourteen-inch model are not in the current requirements of chip maker.
Meanwhile Samsung launches a new all-in-one with a touch screen, Samsung launched a new model all in one computer touch screen. DP700A3B called a model aimed at business and home consumers with 23-inch screen and a balanced set of hardware for your proposal. The computer offers an Intel Core i5 2390T which operates in conjunction with a very strong power of 8 GB of RAM. Without the use of a dedicated video card all in one company’s stake.
With the 23-inch screen offers a pleasant computer experience in high-definition video. The operating system is Windows 7 Home Premium 64 bits. There is also a model with a smaller processor, the Core i3 2120T we in turn can also choose a lower memory 6 GB of DDR3 RAM. With Full HD resolution would be expected to have a Blu-ray drive, while Samsung wish to offer just the DVD combo drive. The computer storage is provided by a 1 TB hard drive with 7,200 rpm.
Besides all this, the computer provides resources such as USB 3.0 connectivity, four USB 2.0 ports, Bluetooth 3.0, 802.11 and HDMI port. The new all-in-one Samsung is priced at $ 999 and can now be found in the North American market.

Some Knowledge That You Don’t Know About Laptop Battery
A battery has two essential characteristics, the voltage in volts (V) and the amount of electricity expressed in Ampere-hours (Ah) or milliamp hours (mAh). The battery power is calculated as follows: Voltage (V) x amount of electricity (Ah) = Energy (Wh). For example: 19.5 V x 4400mAh = 85.8 Wh. Thus we speak of capacity for energy instead of power as general.
What type of batteries used in laptops?
At present, all the batteries that come with laptops are made using Li-Ion technology. These are a type of lithium in the lithium ion remains in the state. These batteries are expensive and that lithium is an expensive material. Its main advantage is the amount of energy we can store in a small volume.
Key Benefits
* No memory effect or very low
* Excellent amount of energy / volume due to the physical properties of lithium.
* Auto-download (natural discharge when the battery is not used) minimum.
* Much safer in relation to the first lithium batteries (in the metallic state) thanks to an integrated electronic circuit.
The main drawbacks
* Price, because of the complexity of manufacture and the material used (lithium)
* Significant deterioration when the battery is discharged below 10% (can lose up to 20% capacity at once!).
* Current limited load because of their internal technology and the danger of lithium, so the burden may seem slow.
* Low temperature resistance: It is recommended to use at a temperature between 20 and 25 ° C, and should not exceed 40 ° C if they can not hurt. Never be achieved at elevated temperatures in the range of 75-80 ° C because they may explode.
* As all these batteries deteriorate over time and nothing can reverse this process.
But you should pay attention to. The overall battery (batteries, lead acid batteries or lithium batteries, etc..) Pollute the environment so it should never be thrown away. They should be recycled (in some countries will find in supermarkets and computer stores where you can leave them for recycling). Never attempt to open a battery to repair it because you can burn or severely intoxicated.

When Sony introduced the first lithium-ion battery in 1991, knew the potential risks to safety. A memory of rechargeable lithium metal was previously issued a stern warning of discipline must be careful in dealing with the system of batteries with high energy density.
Pioneering work of the lithium battery began in 1912 by GN Lewis. It was not until 1970, when the first rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium in the eighties. These early models were based on lithium metal and offers a very high energy density. However, the inherent instability of lithium metal, especially during charging, put a brake on development. The cell had the potential for heat dissipation. The temperature would rise rapidly to the melting point of lithium metal and cause a reaction. A large quantity of rechargeable lenovo t400 battery sent to Japan had to remember, in 1991 after the package on a phone released hot gases and inflicted burns to the face of a man.
Due to the inherent instability of lithium metal, research shifted to a non-metal lithium-ion battery. Although slightly lower than the energy density, the lithium-ion system is safe, provided that certain precautions are met when charging and discharging. Today, lithium-ion battery chemistries be more effective and safe. Two billion cells are produced each year.
Lithium ion is twice the dell latitude d630 battery of a nickel and four times that of lead-acid. Lithium ion is a low maintenance, an advantage that most other chemistries can not claim. There is no battery memory and requires no programming to extend their life cycle. Nor is the lithium-ion batteries have the problem of lead-acid sulfation occurs when the battery is stored without periodic charging finish. Lithium ion has a low self-discharge and the environment. The removal of the causes minimal damage.
With the widespread use of lithium ion batteries in cell phones, digital cameras and macbook pro battery, as is inevitable question. One in all, 200 000 failure rate has led to the withdrawal of nearly six million lithium batteries used in laptops packages produced by Dell and Apple. Battery heat-related chess is taken very seriously and producers have chosen a conservative approach. The decision to replace the batteries puts consumers at ease and the lawyers at bay. Let’s look at what’s behind the withdrawal.
Sony Energy Devices (Sony), the manufacturer of lithium ion cells in question, said that on rare occasions, microscopic metal particles in contact with other parts of the dell latitude d830 battery, causing a short circuit in the cell. Although battery manufacturers strive to minimize the presence of metal particles, complex assembly techniques that the removal of all metal powders almost impossible. High energy density of the cells with ultra-thin separators are more sensitive to impurities than the older models with low grades Ah.
A sweet short only cause an increase in self-defense. Little heat is generated due to the discharge of energy is very low. However, if a sufficient number of microscopic metal particles converge at one point, a short circuit can develop serious and significant current flows between the positive and negative plates. This causes an increase in temperature, leading to thermal runaway, also known as ventilation with a flame.
Lithium-ion cobalt cathode (as recalled dell inspiron 1545 battery) should not exceed 130 ° C (265 ° F). At 150 ° C (302 ° F), the cell becomes thermally unstable, a condition that can lead to thermal runaway in which the gases are vented fire.During a thermal runaway, the heat of the defective cell may extend into the next cell, making it unstable and thermally. In some cases, there is a chain reaction in which each cell disintegrates in your calendar. A package can be destroyed in seconds in the short to dwell on a number of hours that each cell is consumed one by one. To increase security, the packages are equipped with dividers to protect the cell does not spread to neighboring cells.

Tips when buying a computer
In a single decade, the computer has become a regular equipment in many workplaces and it is no longer unusual to find users with a Dell Latitude E6400 battery laptop in tow in a coffee shop, a park or traveling. The computers are part of our lives more than ever, and for this reason, we should know how to buy a suitable computer for ourselves.And maybe the following tips are useful for all.
The first thing to consider is what you need on your computer. It’s not the same to look for a powerful machine to run games, one for work tasks, to surf the Internet or for entertainment such as listening to music, watch videos. If you choose the first option, the game , the processor and graphics card should be powerful, something quite expensive final price. The monitor must be purchased separately , looking for one that is large and with good resolution. Generally, for this purpose, often recommended a desktop computer such as Dell Latitude E6500 battery one , although there are portable very competitive in the market.
If you are looking for a job or household tasks , and to connect to the Internet, you do not opt for the more powerful of the market and another one with good RAM, and a more decent hard drive, and ports connection, disk drive, etc. In this case, it is interesting to note in the comfort and ergonomics that only in the technical. Thus the choice of the screen, mouse and keyboard usually grow in importance depending on the space becomes available in the home or workplace. It is also interesting to distinguish between desktop and Dell xps m1210 battery laptop, but usually opt for the former, since, being many hours on the computer the position of the body is healthier.
If purchased in order to store large amounts of audiovisual material is preferable to a laptop like Dell xps m1310 battery laptop. In addition, a large hard disk is more important than a fast processor. Also highly recommended is a high connectivity with at least four USB ports, multimedia HDMI, SD card slot and Bluetooth connectivity. Finally, you must have a good DVD reader and CD, to resist use of intensive reading and copying. The screen, is not necessarily very large, but it must have a good resolution.
Mobility accumulates importance, but also ergonomic to spend more and more hours in front of the screen.They are usually more expensive and less efficient energetically than a desktop. Who opt for a Dell xps m1330 battery laptop will be clear that you need to move with it, or who needs to win in an address space. With a desktop ergonomic gains in energy efficiency and plasticity, ie the ability of the desktop to accept new internal hardware components that make them stronger or give more memory.
