Simulations show why Bacteria Cheat and Cooperate

More robust treatments for antibiotic-resistant bacteria could result from research at the University of Zurich that simulated interactions among bacterial colonies, using an SGI supercomputer there. The research investigated the cooperation between colonies of bacteria, and could have other applications, including the treatment of Cystic Fibrosis. Dr Akos Dobay, a post-doctoral researcher for the Institute […]

Easily Scale Lustre to Petabytes of Data

lustre-logo2

This week we look at various attributes including how easy it is to scale Lustre file systems. The inherent scalability of Lustre aggregates storage capacity across many servers. I/O bandwidth also scales as more storage servers are added, and can be dynamically adjusted as needs change and demands for more storage capacity and bandwidth grow.

Slidecast: Energy-efficient Computation

mark

“A crazy idea was born at ISC14 while answering questions about the new energy metrics in Allinea Performance Reports and Allinea MAP – could the information in these reports show us an easy way to increase energy efficiency without having to change the program? The idea was to use CPU frequency scaling to run memory-bound jobs at a lower clock frequency. In Lazy Energy Efficiency Challenge One, I found that on a synthetic benchmark I could increase the iterations per watt by 19% on a memory-bound code.”

Why Create a New Programming Language with Chapel?

Brad Chamberlain

“Scalable parallel programmers (and desktop parallel programmers, for that matter) would benefit greatly from a productive new language supporting better syntax, features and optimizations than today’s parallel notations offer. HPC has a rich set of lower-level technologies upon which to build and numerous failed parallel languages from which to learn.”

IBM has teamed with UNSW Australia and Brazilian health institute to examine big genomic data using IBM’s World Community Grid. The project seeks to make about 20 quadrillion comparisons of 200 million proteins underlying a wide variety of organisms.

Making the Cloud Easier to Use

Tom Wilkie, Scientific Computing World

“The cloud is ready for high-performance computing (HPC). Enthusiasm is large, but progress is slow,” Karsten Gaier from the software vendor Nice told the ISC Cloud conference in Heidelberg at the end of September. Why should this be so since, as Thomas Goepel from HP pointed out, the cloud ought to be attractive to small and medium sized enterprises that cannot afford their own supercomputing clusters?

A Petitition for Better Research Software

HzCBwJSLmZidOOD-556x313-noPad

“We want a research environment in which software-reliant projects are encouraged to hire software developers, rather than having to hide these valuable staff members in anonymous postdoctoral positions. Ultimately, we want the research community to recognize software’s fundamental role in research. Everyone who signs this petition will add weight to our lobbying of research stakeholders, and will help us prove the fundamental role of software in research.”
