In previous posts on this blog, Berkeley’s David Patterson, Intel’s Andrew Chien, and Microsoft’s Dan Reed presented their views on why research advances are needed to overcome the problems posed by multicore processors. In this piece — the fourth (and possibly final) entry in the series -– Marc Snir from UIUC argues that there are major challenges facing us but yet, the sky is not falling. — The CCC blog has published a couple of articles on the multi-core challenge, all emphasizing the difficulty of making parallel programming prevalent and, hence, the difficulty of leveraging multi-core systems in mass markets. The challenge is, indeed, significant and requires important investments in […]

Things always change fast in computing. But the rate of change seems to be on a major uptick recently. In this post, I want to focus on an accelerating driver of that change, a looming crisis on the horizon, and a surprising link between the two that may have big promise. In the spirit of blog discourse, let’s lay this out in broad strokes: The Industrial Revolution of Data. Today’s world-wide web remains a staggering tribute to the typing abilities of the human race. But even with a growing global population, typists are not a scalable source of bit-production going forward. We are entering an era where the overwhelming majority of […]

One of the visioning activities supported by the CCC is exploring the possibility of a compelling research agenda in the theoretical, experimental, and societal aspects of “network science and engineering” (NetSE). A NetSE Council has been established.  It’s chair, Ellen Zegura, provides this brief status report on the NetSE Council’s activities. Thanks for the opportunity to update the community on what has been happening recently with the Network Science and Engineering (NetSE) effort, from my perspective as chair of the NetSE Council. Let me explain my take on NetSE with an anecdote from my Georgia Tech colleague Mike Best based on a recent trip he made to Africa. Mike and […]

In previous posts on this blog, Berkeley’s David Patterson and Intel’s Andrew Chien presented their views on why research advances are needed to overcome the problems posed by multicore processors. In this piece — the third in a series -– Microsoft’s Dan Reed gives us his views on some of the potential benefits of progress in this research area. — For over thirty years, we have watched the great cycle of innovation defined by the commodity hardware/software ecosystem — faster processors enable software with new features and capabilities that in turn require faster processors, which beget new software. The great wheel has turned, but it no more, as power constraints […]

The problem of parallel computing is occupying the minds of a growing number of researchers. Why is this age-old concept so “hot” today? In this article — the second in a series of opinion pieces –Andrew Chien, Vice President and Corporate Technology Group Director for Intel Research, gives us his perspective on the issue, with a particular focus on the challenges facing us in education and funding.

Today’s issue of Science Magazine has an article by Luis von Ahn, a computer science professor at Carnegie Mellon University, and several of his colleagues. The article describes the principles and experience behind reCAPTCHA, the “human computation” system that enables web sites to stop spambots while simultaneously digitizing books. As I mention on my personal blog (at http://csdiary.org), this points out a somewhat strange aspect of computing research, namely that there isn’t much computing research in the major core-science publications. I’m thinking specifically of Science magazine, Nature, and PNAS. In fact, I took a quick scan over the past 5 issues of Science and Nature.  Over those issues, in Science […]
