Tata Supercomputer is World's 4th best

November 13, 2007 14:30 IST
After proving its mettle in areas like steel, automotive and IT services on the global arena, corporate behemoth Tata group has now developed the world's fourth fastest supercomputer that can do 117.9 trillion calculations per second.

The supercomputer "EKA", which means number one in Sanskrit, was named Asia's fastest and the world's fourth fastest in the Top 500 Supercomputer list announced at an International Conference for High Performance Computing at Reno (California), USA, on Monday night.

This is the first time that such a system developed in India has been ranked among the world's ten fastest.

Supercomputers are primarily used by universities, military and scientific research labs. They are used in high calculation-intensive jobs like quantum physics, weather and climate research, study of chemical compounds, simulation of aircraft in wind tunnels and detonation of nuclear weapons.

A total of nine supercomputers developed in India have appeared in the Top 500 list, including one more system (179th) developed at Tata Sons' wholly-owned subsidiary Computational Research Laboratories (CRL) in Pune, where EKA was developed.

Others include a system developed at Indian Institute of Science (58th) and six IBM systems (ranked at 152nd, 158th, 336th, 339th, 340th and 371st) developed in the country.

The group chairman Ratan Tata said in a statement: "High performance computing solutions have an ever-increasing role in the scientific and new technological space the world over.

The Tata group has supported this development activity and is extremely proud of the team that has developed and built this supercomputer, which is now ranked the world's fourth fastest.

Secure your mobile wireless device

By Jessica Dolcourt (12/15/2006)

Editor's note: This article was updated on 7/17/2007.

Wi-Fi technology provides the freedom to access the Internet from virtually any location using increasingly sophisticated portable devices. The "cool" factor of e-mailing and instant messaging when you're out and about is so compelling that protecting the device from malevolent invaders is often overlooked. Unfortunately, the same network access that makes online mobility easy for you is also convenient for computer criminals, and even a quick browse can attract damaging codes.

Securing mobile applications requires more effort up front than securing your wireless home network, for two reasons: First, desktops and laptops run on a full-featured operating system that often comes with varying levels of built-in security. Mobile devices, on the other hand, generally leave Internet security up to the user. Second, as each device comes with its own operating system, security software can take time to track down. For instance, BlackBerrys run on a proprietary operating system; Pocket PCs run on Windows Mobile; and Palm devices, like the Treo, run on the Palm operating system. Interoperability is still on our wish list, but here are three steps for protecting your BlackBerry, your Palm device, or your Windows Mobile/Pocket PC from Internet threats.

Step 1: Secure the network

Airscanner Mobile AntiVirus can defend against Trojan horses as well as viruses.

It's hard to overemphasize the importance of online security for any network. Since going online is a secondary function for most mobile device users (surfing and sending data come first), securing the connection may not seem as urgent--and that's exactly what exploitation architects are counting on.

The good news is that mobile wireless security is a growing sector, and some solid programs exist to keep the worst network infections at bay. Owners of a Palm device or a Pocket PC can deflect wandering enemies with Trend Micro's reliable PC-cillin Internet Security. Windows Mobile users have other options at their fingertips with F-secure Anti-Virus and Airscanner Mobile AntiVirus Pro.

Symbian smart phones get an extra boost with Commander Mobile Anti-Virus. JiWire SpotLock supports AvantGo handhelds.

Step 2: Block out thieves

The physical world is another source of threats to handheld security. The most recent spate of corporate laptop thefts are a harsh reminder your sensitive data can fall into the wrong hands. Though odds are thankfully low, a thief could conceivably use your information to assume your identity or swipe your e-mail contact list to fuel a spam campaign. At the very least, you'll want to keep out the boldest of snoops.

The most straightforward method is to enable the password lock found in your handheld's native system settings. You'll want to ensure you set and test a strong password that will frustrate any thief who has gotten hold of your device and has leisure time to tinker.

Step 3: Protect your data

Ilium Software's eWallet uses 256-bit RC4 encryption to protect your data.

Setting the password on your device is an important physical security layer to which software applications provide stronger support. One way to keep your data personal is to use a lockbox program that requires a password each time you access your information. eWallet Professional for Pocket PC helps you create and organize a wealth of information--including credit card, bank account, and car details-- into password-protected categories. CryptMagic performs a similar service for BlackBerry users, and Palm aficionados may appreciate Secret.

WiMax

WiMAX, the Worldwide Interoperability for Microwave Access, is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which is also called WirelessMAN. WiMAX allows a user, for example, to browse the Internet on a laptop computer without physically connecting the laptop to a router, hub or switch via an Ethernet cable. The name WiMAX was created by the WiMAX Forum, which was formed in June 2001 to promote conformance and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL."

Fixed WiMAX

This is a phrase frequently used to refer to systems built using 802.16-2004 ('802.16d') as the air interface technology.

Mobile WiMAX

A phrase frequently used to refer to systems built using 802.16e-2005 as the air interface technology. "Mobile WiMAX" implementations are therefore frequently used to deliver pure fixed services.

Uses

The bandwidth and reach of WiMAX make it suitable for the following potential applications:

• Connecting Wi-Fi hotspots with each other and to other parts of the Internet.
• Providing a wireless alternative to cable and DSL for last mile (last km) broadband access.
• Providing high-speed data and telecommunications services.
• Providing a diverse source of Internet connectivity as part of a business continuity plan. That is, if a business has a fixed and a wireless Internet connection, especially from unrelated providers, they are unlikely to be affected by the same service outage.
• Providing nomadic connectivity.
