Scientists break the terabyte barrier system of
Computer Science at the University of California, San Diego (USA) broke "the terabyte barrier"-and a world record by ordering more than one terabyte of information (1.000 gigabytes or 1 million megabytes ) in just 60 seconds. In competition Friday, July 30, 2010

-the "World Cup of ordering data" - computer scientists at the Jacobs School of Engineering at UC San Diego also tied the world record for the fastest rate system. Ordered a zillion records in 172 minutes and did it with only a quarter of the computational resources of the previous record. Companies
for trends, efficiency and other competitive advantages have turned to this kind of arrangement which requires heavy hardware processing power of typical data centers. The Internet has also created several scenarios where the information system is critical. Advertising on Facebook pages, personal recommendations from Amazon, and search results as Google-second of all are the result of huge data sets to order multiples of petabytes. A petabyte is 1,000 terabytes.
"If a big corporation would run a query across all visitors to their sites or products sold, may need to order a set of multi-petabyte data and especially those that grow to several gigabytes per day," computer says Professor UC San Diego Amin Vahdat, project leader. "Companies are taking to limit the amount of information that can be ordered, and how fast. This is analysis of information in real time, "said Vahdat. We need better management technologies, however. " In data centers, the system is the most common bottleneck in many high-level activities, "said Vahdat who directs the Center for Network Systems (CNS) at UC San Diego.
The two new world records for the UC San Diego are among the recently disclosed results sortbenchmark.org - site run by computer scientists from academia and business volunteers who run the competitions. These powers provide marks in terms of data systems and a forum Interactive researchers working to improve management techniques. World Records
This is the first year that scientists enter the competition and win in the Indy Land in a Minute and Order Indy Gris.
In the first, the researchers instructed 1.014 terabytes in a minute - breaking the minute barrier for the first time.
team also tied the world record in the "Land Indy Grey" which measures the rate per minute system 100 terabytes of information.
"We use computers a quarter of the previous team record was used to achieve the same rate law - which meant using only a quarter of electricity, cooling and physical space," says George Porter, a research scientist in CNS of the UC San Diego.
Two world records fall under the category "Indy" - which means that the systems were designed around specific parameters for competition. The team aims to generalize their results to the competition, "Daytona" and that can be used in real environments.
"The system is also an interesting way to various information processing problems. In general, it is a good way to measure how fast can you read a lot of data from a disk set, apply some processing, distributed by a network and write another set of disks, "said Rasmussen. "Sort puts too much pressure on the subsystem input / output, from hard disks and network cards to the operating system and applications." Balanced Systems
The challenge of sorting data that scientists are taking very different from the modest systems that systems Conventional databases can be done by comparing two tables. The biggest difference is that the laws of terabytes and petabytes of data beyond the memory capacity of the server that makes it.
establishing the system of heavy-duty system, scientists are designed to roll and quickly. A balanced system is one in which resources such as memory, storage and network bandwidth, are fully exploited and only a few resources are wasted.
Breaking terabyte barrier under the national Indy in a minute, the researchers built a system made of 52 computer nodes. Each node is a standard server with two quad-core processors, 24 gigabytes of memory and 16 drives all interconnected by a Cisco switch Nexus 5020. Cisco switches donated as part of the research sought they have with the Center for Network Systems at UC San Diego. The computer cluster is hosted at the Institute for Telecommunications and Information Technology California (Calit2).
To win the Indy Land Gray, investigators ordered a zillion records in 10,318 seconds (approximately 172 minutes), leaving his world record tied with a ranking of 0,582 terabytes per minute per 100 terabytes of data. The winning system is made of 47 nodes similar to those used in the order of a minute.
100 terabytes of information equal to 4,000 Blu-Ray of a layer, a layer DVDs 21.000, 12.000 dual-layer DVDs or CDs 142.248 (assuming are CDs of 703 MB).

"We set our agenda for research on how to improve it ... also make it more generic," says doctoral student in computer science at UC San Diego Alex Rasmussen, leader of the team graduate students.

"Our system shows what is possible if one pays attention to efficiency - and there is still much to improve," Vahdat says "We ask the question What does build a balanced system in no system resources are being missed having a high performance computing? If you have unused or idle processors all the RAM, you're wasting energy and losing efficiency. "Memory often uses the same energy as a processor or more including, for example, but nobody notices that.
