16:20-16:30 Concluding remarks by Talat S. Rahman
Yeah... this went a tad bit over (we actually finished right around 16:30, though, by deferring Altaf's talk and the ones after that to after lunch, and having those during the round table session from 14:15 on).
The KMC project addresses the problem of scaling up and speeding up atomic-scale simulations of nanomaterials processes such as formation of islands and thin films in metal vapor deposition. Deposition is used to manufacture semiconductor wafers and high-density optical recording media such as CD-Rs, DVD-Rs, and Blu=Ray. A long-term goal of the research is to extend this to other nanostructures such as C60 (also known as fullerenes or buckyballs) macromolecular structures in biochemistry: proteins and peptides, genomic structures (histones, chromatin, mRNA, etc.
The project started in January, 2004, when Talat, Kader, Virg, Jacques and I wrote a proposal to NSF. It was one of the last round of ITR grants to be awarded. Since then, we've been busy learning to speak one another's languages. On our en, this has necessitated our learning about solid state physics and simulation methods; on their end, parallel programming and algorithms, genetic and evolutionary computation, and machine learning.
Here are links to the nascent Tiki for the LEAP-KMC project/a>, built originally by Summer Undergraduate Research Opportunity Program (SUROP) participants Sadie L. Bell and Moises Figueroa, and to last year's workshop page. If you are interested in the parallel and distributed computing, machine learning, and GEC research and results that are coming out of our work, check this Tiki as we populate it with the slides from the workshop this week, and with preprints of papers over the summer.
The high school students did indeed work hard this year, and gave two rather nice talks. Kudos to Ahlam Al-Rawi, Talat's research associate, and her undergrad organizers, Asma (her daughter) and Nameer (Talat's son).
All in all, we're all pleased with the progress thus far, though there's a lot more to be done. martinsamuel, weninger, and I will be busy with this work in the coming year. I can tell you that I for one know how these kids felt:

1 There are several of us to credit or blame for that acronym. I believe it was Virg Wallentine, our department head, who suggested an acronym, Abdel Kader Kara, one of the Principal Investigators, who was calling it SL-KMC or ST-KMC for Self Learning/Teaching, and me who suggested "enhanced" because IIRC it was drifting towards Learning Adaptive Parallel and LeAP sounds better than LAP. Well, less unsavory, anyway.
