Reminder: All-Hands Meeting to Discuss CS Strategy at 11 a.m. Today (Sept. 23)

All Computing Sciences staff members are encouraged an all-hands meeting at 11 a.m. today to discuss CS strategy. The meeting will be held in the Building 50 Auditorium. Kathy Yelick will use the meeting to begin developing a Computing-Sciences-wide strategy that clearly articulates our long-term scientific goals and how the facilities and research organization plan to work together to achieve those goals.

Last week, Kathy sent a message to all staff encourage them to contribute their ideas through an online survey at http://www.surveymonkey.com/s/NYQZ39G.

In addition to influencing the strategic plan, this information can help to better represent your perspective in discussions with funding agencies, development of future LDRD initiatives, and deciding where to allocate resources.

Big Data: The ESnet Perspective 

As part of the Lab’s ongoing video glossary project to explain science and engineering concepts, ESnet Director Greg Bell was asked about big data. In a video, Bell explains how big data is transforming scientific discoveries in the latest Berkeley Lab video glossary entry.

ASCR Discovery Online Magazine Highlights Aydin Buluç’s Biofuels Research 

ASCR Discovery, an online publication highlighting research supported by DOE’s Office of Advanced Scientific Computing Research recently posted an article about one aspect of the work being done by Aydin Buluç of CRD’s Future Technologies Group.

“Energy scientists hope new plant varieties will yield large amounts of biomaterial, which new types of microbes will quickly and cheaply convert into clean-burning fuel,” the article begins. “To achieve these goals, researchers will need novel algorithms that enable supercomputers to sift through the combined genomes of several hundred plants or microbes in search of useful genes. With support from a DOE Early Career Award, Berkeley Lab Computational Researcher Aydın Buluç will develop faster and more energy-efficient data-mining algorithms in the quest for new biofuels.” »Read the full story.

Supercomputing: A Toolbox to Simulate the Big Bang and Beyond 

As part of a communications emphasis on supercomputing for the month of September, DOE Public Affairs has posted an article on a joint project to develop a cosmological simulation analysis toolbox. This past year, Fermilab began a unique partnership with Argonne and Lawrence Berkeley National Laboratories on an ambitious advanced-computing project. Together the three labs are developing a new, state-of-the-art cosmological simulation analysis toolbox that takes advantage of the Energy Department’s investments in supercomputers and specialized high-performance computing codes. Argonne’s team is led by Salman Habib, principal investigator, and Ravi Madduri, system designer. Jim Kowalkowski and Richard Gerber are the team leaders at Fermilab and Berkeley Lab. »Read more.

This Week’s Computing Sciences Seminar 

IPython: an architecture for interactive scientific computing across languages

Thursday, September 26, 2 – 3 p.m., Bldg. 50B, Room 4205
Fernando Perez
(Creator of the IPython project), Henry H. Wheeler Jr. Brain Imaging Center, University of California, Berkeley

Abstract: IPython is an open source environment for interactive and parallel computing that supports all stages in the lifecycle of a scientific idea: individual exploration, collaborative development, large-scale production using parallel resources, publication and education. The web-based IPython Notebook supports multiuser collaboration and allows scientists to share their work in an open document format that is a true “executable paper": notebooks can be version controlled, exported to HTML or PDF for publication, and used for teaching.

In this talk, I will describe how a single, coherent architecture covers this entire use spectrum, emphasizing examples of its use in HPC and parallel computing problems. In these contexts, IPython can be used both as a standalone tool for high-level parallel computing or in conjunction with MPI codes to provide dynamic control that complements MPI's traditional strengths.
