Juan Meza Named New Dean of Natural Sciences at UC Merced

Juan Meza, acting director of the Computational Research Division and head of CRD’s High Performance Computing Research Department, has been named Dean of the School of Natural Sciences at UC Merced. The appointment, announced Friday, June 3, will be effective this fall.

“As I was considering this position, I was truly impressed by the quality of the faculty, the commitment and diversity of UC Merced's students and the great potential to help shape the development of the newest campus in one of the world's best public university systems,” Meza said. “I'm looking forward to tapping into this great potential to help develop each student as an individual and the institution as a whole.” Read more.

CS Staff Give Keynotes, Talks at Federated Computing Research Conference

Once every three or four years, the Association for Computing Machinery (ACM) sponsors the Federated Computing Research Conference (FCRC), an assemblage of 16 affiliated research conferences and workshops, at a weeklong coordinated meeting held at a common time and place. FCRC’11 is being held this week at the San Jose Convention Center, and Computing Sciences staff are giving a number of keynote presentations and talks. Here is a day-by-day look at some of the Lab staff presentations:

  • Krste Asanović is co-author of a paper on “Exploring the Tradeoffs between Programmability and Efficiency in Data-Parallel Accelerators” to be presented at ISCA 2011, the 38th International Symposium on Computer Architecture.

Wednesday, June 8

  • Jim Demmel, a professor of computer science at UC Berkeley with a joint appointment in CRD’s Scientific Computing Group, will give an invited talk on “Accurate and Efficient Expression Evaluation and Linear Algebra, or Why It Can be Easier to Compute Accurate Eigenvalues of a Vandermonde Matrix than the Accurate Sum of 3 Numbers” at SNC 2011, the Symbolic Numeric Computation Workshop.
  • Julian Borrill of CRD’s Computational Cosmology Center will give a talk on “Cosmic Microwave Background Data Analysis at the Petascale and Beyond” at the Workshop on Dynamic Distributed Data-Intensive Applications, Programming Abstractions, and Systems (3DAPAS). CRD’s Keith Jackson is on the workshop organizing committee.
  • Lavanya Ramakrishnan, Scott Campbell, Shane Canon, Iwona Sakrejda, and Tina Declerck of NERSC are among the authors of “Magellan: Experiences from a Science Cloud,” a paper to be presented at ScienceCloud2011, the 2nd workshop on Scientific Cloud Computing.

Thursday, June 9

Yelick, Patterson Discuss Parallel Programming in The Economist

Parallel programming, once an obscure niche, is the focus of increasing interest as multicore chips proliferate in ordinary PCs, according to the article “Parallel bars” in the June 2 issue of The Economist. NERSC Division Director Kathy Yelick and UC Berkeley professor David Patterson, who has a joint appointment in the Computational Research Division, are two of the experts quoted in the article, which discusses both the necessity and the difficulties of parallel programming.

Influence Region Downscaling
Wednesday, June 8, 12:00–1:00 pm, 50B-4205
Kate Marvel, Stanford University

We present a new empirical downscaling method based on observed correlations between climate variables. We describe how to calculate the “influence region” for a given point on a high-resolution grid, and show how this region varies with timescale. This new method can be applied to observed temperature and precipitation time series, and used to extrapolate local climate behavior into the future using lower resolution general circulation models. Using these extrapolations, we investigate the emergence of extreme events, and show how this behavior can be localized.

Link of the Week: China Cranks Up Heat on Nuclear Fusion

Is China’s latest technological drive going to end up producing yet another Sputnik moment for the U.S.? That has to be one question on the minds of scientists, researchers and politicians in the U.S. as China unveils its latest attempt to reach for one of science’s brass rings: viable nuclear fusion technology.

According to a report in the state-run China Daily, the central government is planning to train 2,000 experts to pursue research and development into magnetic confinement fusion, which seeks to use magnetic fields to create the high-pressure conditions necessary for fusion.
