The DILIGENT team used the EGEE computing Grid to process 37 million images from the online Flickr database in just 16 weeks. This computation generated approximately 112 million text and image objects—nearly 5 TB of data—containing more than 150 million extracted features. This is equivalent to an average processing capacity of over 300,000 images per day.
This unique collection will be used by the SAPIR project to develop new large-scale content-based data retrieval and automatic data classification techniques that combine both text and image content, expanding the limits of conventional search engines, which can only search text associated to images and audio-visual content.
The computational load required to generate this massive data collection was outsourced to DILIGENT, and then delegated to the EGEE Pre-Production Service (PPS) Grid infrastructure via the gLite middleware. A total of 44,333 gLite jobs were successfully executed by the EGEE PPS infrastructure resource broker. Each job processed approximately 1000 images.
The data challenge lasted for 116 days, from 16 June to 9 October 2007, and was organized in three different phases. During the initial preparation phase experimental jobs were submitted to some EGEE PPS sites to test the feature extraction application and optimize the number of images to process per day.
The next two phases involved actual execution of the data challenge, exploiting ten EGEE PPS sites that contributed their computational resources: University of Athens, Scuola Normale Superiore, ISTI-CNR, LIP, ESA-ESRIN, CERN, CESGA, University of Macedonia, Ben Gurion University, and CYFRONET. Four of these sites are maintained by DILIGENT partners.

New 3-D wiring technique brings scalable quantum computers closer to reality
19.10.2016 | University of Waterloo
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
