Hardware

ScienceNode talked to Larry Smarr about the Science DMZ (De-Militiarized Zone) concept. Smarr sees the Science DMZ as analogous to building the city freeway systems, whereas the campus-shared internet systems that support non-science missions are like the city streets. This Science DMZ network architecture is needed because big data and routine applications have different bandwidth and performance requirements. He notes: "In the case of Science DMZs, this was another example of the DOE developing an idea with its national laboratory system and then the NSF moving it to an even larger scale across all research campuses in the country."

Applications

Adrian Jackson continues the discussion he started about Software design in scientific computing on the EPCC blog. He notes: "One of the key design areas for software, which often is not properly considered and can have a big impact on applications later in the development process, is the changeability of a program." He sees the real strength of adding a small amount of software design to your development process is not just in helping to ensure that the program is sensibly structured from the start, allowing easy modification and maintenance where most required, but also it allows evaluation of your programs once development has progressed.

Crowd computing

Crowd Computing infrastructure Folding@Home reports that in terms of Flop/s performance it is closing to 100 Petaflop/s, which would be a major milestone in computing. In terms of the ability to tackle complex systems, Folding@Home is simulating considerably bigger, more complex systems for longer timescales than ever before. Over the last 3 years, Folding@Home has seen a few trends, especially consolidation into people to use GPUs and the increase in power from those GPUs. Folding@Home estimates that today it is running off the power of about 40.000 GPUs. Read further...
