The first goal of the Academic Cluster Computing Initiative was to familiarize the academic community with the methods necessary to run very large datasets on massive distributed computer networks. By expanding that program to include research grants through the National Science Foundation's Cluster Exploratory (CLuE) program, we're also hoping to enable new and better approaches to data-intensive research across a range of disciplines.
Now that the NSF has announced the 2009 CLuE grants in addition to some previous Small Grant for Exploratory Research (SGER) grants, we're excited to congratulate the recipient researchers and wish them the best as they bring new projects online and continue to run existing SGER projects on the Google/IBM cluster.
The NSF selected projects based on their potential to advance computer science as well as to benefit society as a whole, and researchers at 14 institutions are tackling ambitious problems in everything from computer science to bioinformatics. The institutions receiving CLuE grants are Purdue, UC Santa Barbara, University of Washington, University of Massachussetts-Amherst, UC San Diego, University of Virginia, Yale, MIT, University of Wisconsin-Madison, Carnegie-Mellon, University of Maryland- College Park, University of Utah and UC Irvine. Florida International University, Carnegie-Mellon and University of Maryland will continue other projects with exiting SGER grants. These grantees will run their projects on a Google/IBM-provided cluster running an open source implementation of Google's MapReduce and File System.
We're excited to help foster new approaches to difficult, data-intensive problems across a range of fields, and we can't wait to see more students and researchers come up with creative applications for massive, highly distributed computing.

The lens maker claimed you could melt a penny with it, so that was the first thing we tried:
Modern pennies are made of zinc with a copper coating. The bottom row shows what happens when you put a penny in the focal point of the lens: the inside melts away and the coating stays intact (zinc melts at 693 kelvins, copper melts at 1,356 K). But if you heat it just enough, the metals mix and you make brass (the gold-colored penny in the middle). Older pennies (those minted before 1982) are almost entirely copper, so they didn't melt (top row).
We also had an aluminum can:
The water we poured in boiled quickly, while the can itself became so brittle that we poked holes through it with nothing more than sunlight.
Then we tried cooking. Popcorn did both what you'd expect and not quite what you'd expect: when you really focus the light on it, it kinda pops but mostly burns. However, if you don't put it directly in the focal point, so the light is spread over a larger area and doesn't heat it up as quickly, you can get a whole bunch of kernels to pop without burning too much.
The steam/smoke coming up from the kernels really highlighted the spectra from the lens beautifully. Our yield was very low (lots of unpopped kernels for each popped one), but at least we had real popcorn!
When we tried to cook bacon, about a third ended up well done, a third was burnt, and a third was uncooked. Cooking with the lens is difficult because it heats stuff up too hot too fast. But the well-cooked parts tasted great, so we added an egg:
(We didn't lens the spoon; we used it to eat the egg afterwards.)
It's been fun experimenting with different lensing techniques and items and we've learned a lot (including where the nearest fire extinguisher is!). These are just the highlights — we've lensed gourds, soap, gummy bears, CDs — you name it. Next on our list: marshmallows!
We've got more details and more pictures of our results on Alan's personal blog. If you have ideas of other things we should try lensing, we'd love to hear suggestions.
