Curtis Roads is a professor, vice chair, and graduate advisor in media arts and technology, with a joint appointment in music at the University of California at Santa Barbara. He also was the editor of the Computer Music Journal (published by MIT Press), and co-founded the International Computer Music Association. He is often a featured speaker at conferences such as Supercomputing. 
 
Music is an interactive, concurrent process. A note or a chord sounds, then is replaced, gradually or sharply, softly or powerfully, by the next one. For electronically produced or enhanced music, real-time technical advances are critical to continued progress and exploration. In the 1970s, I fondly remember learning my first parallel

Feature - Scientific computing rock stars unveiled We asked you what makes someone a rock star of scientific computing, and you answered. Click on the image for a larger version. When last we polled our readers, we asked you who you think is a rock star of scientific computing. There were many names nominated, including Robert Grossman, director of the National Center for Data Mining, and Malcolm Atkinson, director of the e-Science Institute and the National e-Science Centre in the United Kingdom. Not all of our nominees were available to comment. Nonetheless, we did get three fantastic responses to our wacky rock star questionnaire. Read on to find out about where fame and computing meet! Ian Foster Director of the Computation Institute at Argonne National Laboratory Q: Let's start with the shameless plug part: What are you working on right now, why should your average user or developer care, and why is it super cool and challenging? A: Let

Link of the Week - Nobel Prize follows Ig Nobel

Artist's impression of a graphene transistor. Image courtesy physorg

A first has just occurred in the world of Nobel Prize awards: Andre Geim, a Russian-born physicist, who was previously awarded an Ig Nobel for using magnets to levitate a frog, received a Nobel Prize in Physics for his experiments on a 2-D substance called ‘graphene.’ Graphene, which is one-atom thick and entirely made from carbon, comes from the ‘lead’ in a pencil.
 
The substance is made up of a handful of atoms in a honeycomb lattice, akin to atomic scale chicken wire. At this scale,  its properties truly shine as Andre and his team discovered that the material conducts electricity 100 times faster than silicon. Possible future applications of this material could be for the creation of ultra-fast transistors for the next generation of computers, electronics, smart displays and quantum-dot computers.

SDH-NEERI (Supporting the Digital Humanities/Networking Event for European Research Infrastructures), NEERI will be held at the Technical University of Vienna, Austria.
“Supporting the Digital Humanities” is the first conference that is jointly organized by the CLARIN and DARIAH initiatives, which are building the European research infrastructure for the humanities and related disciplines. SDH2010 aims to bring together infrastructure providers and users from the communities involved with the two infrastructure initiatives. The conference will consist of a number of topical sessions where providers and users will present and discuss results, obstacles and opportunities for digitally-supported humanities research. Participants will be encouraged to engage with honest assessments of the intellectual problems and practical barriers in an open and constructive atmosphere.
SDH2010 is organized toge

Interview - Kostas Glinos peers into his crystal ball

Kostas Glinos is a member of the European Commission’s Directorate-General for the Information Society and Media — and he just presented the European Grid Initiative with a 25-million euro contract in a brief ceremony onstage at the start of the EGI Technical Forum on 14 September. iSGTW caught up with him afterward, during a coffee break held in the middle of the poster session floor. We asked him about the significance of the EC’s backing, his hopes for EGI, and his ideas as to what it all means for the future.
iSGTW: What was the significance of the contract presentation today?Glinos: EGI is the culmination of an effort over eight years to look for a sustainable, long-term commitment from European countries, supplemented by the European Commission (EC). Of a projected 73 million euro cost, 25 million is coming from the EC, with the rest from member states. We n

Podcast of the Week - Alan Sill of OGF discusses standards, grids, and clouds

Open Grid Forum Vice President of Standards, Alan Sill.

It’s been a few months since Alan Sill took over the position of vice president of standards for the Open Grid Forum. Now that he’s had a chance to settle into his new position, Derek Stevens of Cloud Commons has posted an in-depth interview with Sill.
Currently, Sill is a senior scientist at Texas Tech University, where he helped to establish a CMS Tier-3 center and held key positions within TIGRE and PEGrid. He is a charter member of The Americas Grid Policy Management Authority, and has contributed to a variety of working groups within Open Science Grid and the OGF over the years. At the moment he participates in the LHC CMS experiment as a physicist, and contributes to SURAgrid on a regular basis.
According to Sill, a full set of standards for grid computing would necessarily address many of the s

Feature - People behind EGI: Steve Brewer steps in as the voice of the user

With the EGI technical forum coming up in a few weeks, readers may want to know more about the people behind the scenes.
Much of the organization’s success will hinge upon its ability to foster strong communities between users and resource providers. Who will act as a communication point between these two groups? Steve Brewer, a long-time member of the European Grid Community, has recently been appointed chief community officer for EGI.eu, the new organization responsible for coordinating the European Grid Infrastructure.
iSGTW: Where does EGI.eu fit into the grand scheme of things?
Brewer: From physicists, to chemists, to geologists, many European researchers need distributed computing for their work. While these researchers previously used an infrastructure coordinating by EGEE (the project Enabling Grids for E-sciencE), the same infrastructure is now coordinate

Feature - The sky’s the limit

Becky Parker, head of physics at the Simon Langton Grammar School in Kent, UK, is introducing her students to outer space. In 2007, Becky organized a trip to CERN for her 16 to 18 year-old students. There, they were introduced to the Timepix computer chip, a sensitive light-detector used for medical imaging. Back in Britain, one of her students came up with the idea of using the chips to measure cosmic radiation. Parker’s response: “Brilliant!” A Timepix chip has 65,536 pixels over a 2 cm² area. An event occurs when a particle strikes a pixel and is converted into an electrical signal, which can be measured. Her students wanted to use Timepix chips to detect particle type, energy and possibly, the directionality.Consequently, her students entered and won a space experiment competition with their design made from adapting readouts of the chip. Their instrument, called LUCID (Langton

Feature - From EGEE to EGI: Plain talk with Bob Jones and Steven Newhouse

At the Uppsala Gala Dinner, Bob Jones of EGEE handed over to Steven Newhouse of EGI his most prized possession — a crown made from all the name tags he collected from conferences in the past six years. Image courtesy GridTalk

After six years, on 1 May, EGEE will hand over responsibility for the world’s largest grid infrastructure to a new organization dedicated to its coordination and development (EGI.eu), and its newly elected director, Steven Newhouse.
During its lifetime, EGEE — Enabling Grids for E-SciencE — assembled a world-wide infrastructure of CPU cores, hosted by computing centers around the world. Each month, about 13 million jobs are executed on the EGEE Grid.
This massive multi-disciplinary production infrastructure was led until now by Bob Jones who initially, like Steven, held the position of technical director at EGEE, and quickly advanced to project director.

EGEE User Forum Highlights Created with flickr slideshow. Images of EGEE User Conference in Uppsala, Swede. All images were taken by Corentin Chevalier of GridTalk For those of you who were not able to attend the EGEE User Forum in Uppsala, Sweden, here's a few highlights courtesy of the many people who contributed photographs for the use of iSGTW. Here, you can get a sense of everything -- although admittedly not get the experience of such Swedish institutions as cookies and caviar (from a toothpaste tube) for breakfast, served at the Akademi hostel at the University of Uppsala. —Dan Drollette, iSGTW
