Much of the work that SETI@home does is security, combatting those who would submit false or abreviated results in order to get higher stats. UofA want to do real computing on a variety of applications. They've concluded that it is more efficent (for their purposes) to go for a small pool whose results they can trust, than to go for a large pool whose results they have to check and double-check.

      Each approach has significant advantages and disadvantages. It depends on the type of work you are interested in performing.

What happens when a node goes away (someone starts to use the computer for instance) what happens when a new node becommes available? And of course how easy is it to deploy these programs? What you'd like to do is "feed" these programs in via some kind of queue, and allow that queue to be reordered - how does that work? You possibly want to prevent the machines from sleeping or being shutdown, this will also need some UI changes - maybe a machine needs to be shutdown for an upgrade or simply to be moved, how do you over ride the settings? You might also want to see how the programs impact the network (you can imagine that a program could swamp the network with IP traffic if you weren't careful) some form of debuging software that could run on a single machine to simulate it's deployment would also be useful.

    It's also in the Top 500 supersomputer list, so it must be half-decent. So if four universities can have a dencent computer in Canada, others probably do too.

  32. SHARCNET by WEFUNK · · Score: 3, Informative

    I believe they will use high speed networks of Linux based Beowulf clusters (actually clusters of clusters of clusters). Ontario has already established SHARCNET between a number of Universities with a total of over 500 COMPAQ Alphas (mostly four-processor, 833Mhz, Alpha SMPs) and some Pentiums, all running Linux. A press release from last year gives a good overview of the project, already first in Canada and the 11th most powerful academic computing system in North America. I believe the Canada wide project will essentially form a cluster of these cluster of clusters.

    SHARCNET has been up and running for a while and last year accounted for about 27% of supercomputing power in Canada (half of all supercomputing power in Canadian universities), with three sites on the Top 500 list and total power exceeding institutions like Cambridge, Princeton, Cornell and Caltech. There's loads of information available about the hardware and software used at each facility, as well as CPU load and usage statistics at members sites like these status charts from the most powerful individual site, at the University of Western Ontario. As for applications, a number of researchers are already using the system for a variety of projects across science, engineering, and economics.

  33. U of A Computational Resources by altadel · · Score: 3, Interesting

    The University of Alberta has over a dozen clusters. Their central computing facility (CNS) has two clusters, Physics has three or more, CS at least one, Chemistry has seven clusters (0.5 THz total cycles), MechEng at least one, EE at least one, ...

    The U of A (U of Eh?) also participates in MACI (www.maci.ca) and houses three SGI Origin computers, and is involved with the WestGrid project (www.westgrid.ca).

    Prof. Schaeffer's point isn't that we don't have "computrons", but that research is increasingly using simulations (see Jaeger's work) and other computational methods, and computational resources are becoming increasingly overloaded as budgets are not growing as quickly as research advances.

    This would be a cool way to get unrestricted high speed internet into homes...for example, if they were to say, "let us use your idle processes in return for free, unlimited, un-portblocked, static-IP internet that you can run a Domain off!" Sounds like a pretty decent trade to me.

    The government has made all four of its 386s available for this venture, which brings, along with all private computers in Canada, the entire total up to seven.

    However, the government is concerned that the supercomputer doesn't properly reflect Canadian values. For example, the color of the cases is a light beige, which is racist. So all computers as part of this net will be painted multi colors.

    In addition, they must be used to do CANADIAN computation from a CANADIAN programmer at least one run time out of three.

    Not everybody's against global warming, eh? I once got yelled at by a Canadian ex-pat for wearing a Greenpeace t-shirt, because I was clearly an enemy of Canada.


    Actually, climate change has been a real problem for the ecosystem of the north coast, with a lot of ice melt and more open water than usual. One of the effects is that seals have more of the year, or in some places year-round, that they can find open water instead of making breathing holes in the ice. Polar bears and the traditional Inuit hunting methods both depend on catching seals at their breathing holes, so their hunting is much less effective.


    On computer-related topics - laptop batteries really don't like background CPU-burners. I used to run the GIMPS Great Internet Mersenne Prime Search, and I used to commute by train, with about an hour of battery time each way. NiMH batteries don't have the same failure behavior as NiCD, and they're nowhere near as nasty a toxic waste disposal problem, but they really don't like this kind of treatment. To compound matters, for some of that time period, I was running Windows NT 3.51, which was much more stable than Win95, but it insisted on being a *server* operating system that didn't need laptop power management drivers, so when it got a hardware low-power shutdown signal, instead of going into hibernation mode (see, the polar bears *were* relevant), it would blue-screen and die. I had to stop running the prime search.

  40. Physicist programming skills vary widely by billstewart · · Score: 2
    While there are some physicists who'd do that, it's much more likely to be some computer science major who fixes the 1ppm roundoff error that the physicists' code was making (or some math jock who's neither one.) I was an Operations Researcher in college, and later at Bell Labs I was running a computer center used by some of our physicists to do some network simulations. I found that they were using a linear linked list to handle the event list, and converted it to a heap - and was disappointed to find that it only sped the whole program up by a factor of 3-4 instead of 5-10 :-)

    On the other hand, their code basically jumped around in a large matrix, without much locality, because that matched what the real system they were modelling would do. They needed 12-14 MB of table space for the system they were modelling, and our VAX 11/780 only had 4MB of RAM, so I played with a number of virtual memory operating systems (4.1BSD, SVR2.0p, various tunings) to get something that would survive being thrashed to death, and helped them do a lot of work on checkpointing their code, because their standard run took a week, and even if something else didn't cause the machine to crash, we'd get power hits during summer thunderstorms. After about two years of this, the price of RAM dropped to the point that we could afford to upgrade the machine to 16MB, which made our run time drop to about an hour....

    Meanwhile, that Cray-1 of yours was mostly similar in performance to a Pentium 133, and some of the recent graphics chips have really immense memory bandwidth, though they're mostly running fixed-point or at best single-precision floating point rather than double-precision or quadruple-precision, so they're not *quite* a Cray-replacement even though they're faster at many things.

  41. SETI@Home, Canada's Fastest Supercomputer by billstewart · · Score: 2
    According to SETI Stats by Country, there are 212334 Canadian PCs running SETI@Home. I don't know how real these stats are (lots of these may be people who ran the thing once in the past, or who don't run it full time, and obviously this includes lots of computers slower than what you'd build into a modern Beowulf cluster, but it's still quite a bit larger than the network these guys are building. While some of the SETI@HOME network is still listening for space aliens, it's also running a number of earthbound projects like studying protein folding and searching for cancer drugs.

    There are real benefits for Canadian research that can come from this project - certainly there are a number of problems that are numerical and parallelizable, so there can be a lot of future to it if they do enough coordination, but most of Canada's academic supercomputing is currently driven by SETI. Besides scientific research, the other traditional users of supercomputers are weather prediction, oil exploration, and sometimes financial modelling - Canada may have more total supercomputer-based supercomputing than anybody realizes, in addition to SETI. However, the June 2002 top500.org list doesn't show anything in Canada above #227.

    Other results from the Top500.org list - SETI@Home is still about 7 times as large as the largest single machine on the list , Japan's NEC Earth Simulator, which is about 5 times as large as the #2 machine, LLNL's ASCII White.
