Canada to Launch Countrywide Virtual SuperComputer
LadyCatra writes "A serious shortage of world-class computing power in Canada prompted University of Alberta scientists to create the next best thing -- a countrywide, virtual supercomputer.
On Nov. 4, thousands of computers from research centres across the country will be strung together by a U of A effort to create the most powerful computer in this country.
The full story is here"
Why didn't they just make a client program for distributed computing so the entire country/world could help out?
sig.
Yes it is, it really is!
...on Nov. 5, someone will find a way to temporarily use all of this virtual power to play a round or two of half life....
Security perhaps? I wouldn't trust a distributed model for University research. Neither does lucal arts (they could but why would they)
This seems like a really good idea, I don't really understand why more places don't do this. I mean most of us work in offices where the computer power is amazing and largely untapped.
I think what this really needs is to be make easier for the mainstream, so anyone could do it. Perhaps bundle the tools (programming and deployment) with mainstream operating systems?
It's just an idea, my NeXT had Zilla (it's version of this) years ago - seems a shame that this hasn't caught on more widely. So come on Apple - let's see it, put it in the Darwin project and put a nice UI on it in Mac OS X.
Anyway, before activating It, make sure It doesn't have any access to a spare nuclear warhead on orbit around Earth.
I predict this will be the fastest computer that will ever be made in 1996!! Awesome!
Canada's first objective is to get a clue and stop lagging 5-6 years behind America in everything....and for that, they're probably going to need a supercomputer.
Cheers,

"..."A serious shortage of [insert fovorite commodity here] in Canada prompted... "
The list of shortages in Canada seems to grow week by week.
Canaduh just can't seem to get a break, now, can it? I've got a spare Mandrake box I can donate...will that help?
"The Network is the Computer"
It would be nice to see a worldwide system. If this is going to work there must be some CPU time quota system, perhaps a quota that can be bought and sold. This could make it interesting for ordinary home users to join (earn quota, sell quota, make $$$). There are many projects in the academic world that could never make a SETI@home launch, since the research is to boring. Still, we need to use all that idle time buring away across the world.
Imagine a beowulf cluster of these!
Oh..wait, nevermind.
a Beowulf cluster of these!
Sorry...
-- Cheers!
... its a beowulf cluster, aye.
SkyNet!
I had no idea Skynet was Canadian.
That's a fantastic idea ! If this works, we'll be able to use it for useful computation ! It might sound crazy, but with such a virtual computer, one could make computations to help SETI or to cure cancer skyrocket ! How did they come up with such a great idea ?
...all Beowulf posts under this thread, including (but not limited to):
- standard Beowulf trolls mixed with standard Canadian accent lexicon ("eh?", "aboot")
- posts about how a Beowulf cluster could perhaps help Canada out with a stereotypical Canadian "problem" (lousy beer, socialized medicine)
- jokes combining the word Beowulf with the name of the mentioned U of A chemist Wolfgang Jaeger
Thank you.
"The computers will be linked by the Internet, but involve a simple networking system, Lu said. Keeping the linkage as simple as possible was the goal."
Based on the article I would assume that they have made a custom tailored system (if not kludge) for one specific purpose ("for calculating energy shifts as two molecules are manipulated around 3-D space") - and not a platform which could be easily tailored and managed to solve different kinds of tasks with different kinds of relationships between the tasks.
Ohh, I could also link my grid computing links.

Rather than adopting the suggested regime change in Iraq through military force, the United Natioins must instead consider an entirely different course of action. This new course is based upon
the facts alone, rather than political pressure. A regime change is indeed necessary, but not in Iraq. The primary regime which needs to be changed, is the one found in Washington DC. The
greatest tyrant and true threat to world peace who needs to be ousted, is George W. Bush. The facts which clearly show the need for such a resolution against the U.S. are self evident...they
demonstrate a clear and present danger to the world community. America is clearly a nation which aspires to global domination, through the use of the most expensive and high tech
military the world has ever known.
In demonstration of the above assertions, let us be very clear about Americas 300+ billion dollar a year expense, for weapons of mass destruction. These include;
The United States possesses, and has openly discussed using, such weapons of mass destruction upon a great number of other nations. Among these nations are those listed in George Bushs'
so-called axis of evil list, as well as many others which it says, harbor terrorists. The so-called War on Terror targets Libya, Yemen, Saudi Arabia, North
Korea, Iran, Iraq, Afghanistan, Pakistan, Indonesia, Columbia, Nicaragua and many others. Upon these nations the U.S. has repeatedly issued a series of very aggressive and threatening statements
to the effect of; You are either with us or against us, implying dire consequences of economic, diplomatic and military measures in the case of non-compliance. It has openly discussed
the possibility of a first strike use of conventional nuclear warheads, and tactical nukes on the battlefield. Its' military policy of, win no matter what the cost
of truth or human lives, as a surrogate for sane foreign relations, has earned the wrath of the world. U.S. belligerency has been a major contributor to international hostilities,
instability, war and the creation of reactionary terrorist groups, as well as the oppression of peoples worldwide. Its irrational posture threatens to catapult the world into another, and
probably final, world war.
The United States has repeatedly shown its willingness to target civilian populations with weapons of mass destruction, especially via the carpet-bombing of cities and infrastructures. It is
the only nation to have ever used nuclear devices in war, and upon civilian targets. Among the structures bombed have been desalinization plants, water treatment facilities, police stations,
electrical substations and generators, radar and communications stations, hospitals, highway, railway and other transportation facilities, factories for the manufacture of metal, plastic and wood
products, and numerous other civilian centers. Countless examples of this behavior have been witnessed in both Iraq and Afghanistan. The result has been millions of Iraqi and Afghan children
dying of unnecessary diseases and malnutrition, due to a severe lack of food and safe drinking water. U.S. allies such as Israel, (whose military it literally makes possible) have also exhibited
such behavior, as has Great Britain, through constant urging toward mindless, mutually accomplished war frenzies.
A primary export of the United States is weaponry of mass destruction, including so-called conventional weapons such as guided missile cruisers, bombers, small arms, mortars,
rockets, tactical advisors, self guided missiles, attack helicopters, high tech surveilance and imaging systems, tanks, explosives and various other tools desigen primarily for the sake of
destroying human life. Added to this list of exports are multi-lingual propaganda, biological agents, tear and nerve gas, atomic weapons and their constituents, as well as technical advice
regarding their construction, maintenance and use. The U.S. has frequently urged countries to use these weapons against each other so long as it benefitted its political interests, while
simultaneously criticizing those who use them without American sanction.
Permanent State of War
The U.S. has repeatedly told its own citizenry to expect involvement in what amounts to a Permanent State of War, due to the War on Terror. A large and increasing number of
foreign nationals are being held in American prisons unlawfully, often without charges, legal due process or access to legal counsel. These persons are often subjected to psychological and
physical torture due to their nationality or religious beliefs. Its' Afghan prisoners of war in Cuba are treated without dignity, in violation of the Geneva Convention. At the same time, the U.S.
has insisted that its military personnel must be held exempt from war crimes charges by the international community, regardless of their actions.
The United States repeatedly defies the resolutions and authority of the United Nations, making is clear that it views this body as merely a tool which can be occasionally used to achieve its
special interests, rather than those of humanity in general. America has also made it quite clear that if its desires are not met by the international community/United Nations, that it will act
on its own regardless of their wishes, and in whatever manner it sees fit. This includes pre-emptive military invasion of any country which dares to oppose its policies, and for whatever flimsy,
baseless justification it gives to the world as an excuse for such actions.
The international community must seriously ask itself, Who's next? in this series of American invasions of sovereign lands. Who will die next...by the thousands, tens of
thousands or millions... at the bloody hands of American imperialism?
For these reasons and others, it is hereby proposed that:
The functional means necessary to achieve this goal are hereby suggested. They include;
In effect, the United States must feel the full pressure of international sovereignty, as it expresses its supreme dissatisfaction with the US imperialism around the globe.
The United States must also understand that its anti-humanitarian, corporate-minded, industrial-military schemes for global dominance are nothing short of those employed by Hitler, and other
fascist dictators and governments, throughout the course of history. [Constantly declaring war and occupying one country after the next demonstrates this.] The international community, and indeed
the peoples of the entire world, find this American attitude and behavior unacceptable. They will no longer be coerced or made to feel insecure in their own places of residence and worship, at
the behest of American whims.
*oh*, it is a Beowulf cluster! :)

The computers will work jointly on a molecular chemistry research question that would take a single computer as long as six years to complete. Jonathan Schaeffer and Paul Lu, professors in the U of A's department of computer science, expect their virtual supercomputer will do the work in one -- one day, that is.
So how is this different from DC or SETI?
Live for the present, learn from the past, and dream of the future!
On Nov. 4, thousands of computers from research centres across the country will be strung together by a U of A effort to create the most powerful computer in this country.
The most powerfull computer in Canada? So basically they'll have a large collection of computers as powerfull as my 386? But really, how does an entire country have less research computing power than a university?
The article isn't very specific on the kind of problems they will try to solve. The 'search' problems, where you have a big search space than can be easily divided into smaller chunks are easy. Unfortunately some problems cannot be easily split into many independent parts - simulations generally fall into this category. Weather simulations, nuclear explosion simulations, well, simulations in general :-). You can just assign each computer a square mile of terrain, do the computations for the whole simulations, then merge the results - the neighboring squares interact, so computers have to communicate after each time slice. This is where communication will probably slow your 'network supercomputer' down. No matter how fat the pipes are, they will be several orders of magnitude slower than an internal supercomputer bus in terms of latency. To put it short: this might be of some use, but they better start gathering money for a real supercomputer.

From the article Gerald Oakham and his fellow physicists have a problem. In the hunt for the most elusive speck of matter known to science, they are about to generate more data than any computer on the planet can analyse.
My school, in conjunction with the Université de Sherbrooke (mostly the U de S) are setting up a world-class beowulf cluster for general scientific work. A physics professor at my University, who also happens to be a world class astronomer (Dr. Lorne Nelson) has a research grant that he is using to help with the funding for this cluster.

rather than joining a currently existing project? I'm a student at the University of Virginia and we have a project like this that's been going on for 5 years now: http://legion.virginia.edu/
(I think these are a little out of date. There's a bunch of rack-mount machines in there now too)
They talk about how they feel that Canada should be pursuing its own supercomputing, but why not join up with other universities that have been pursuing similar projects and give Canada access to the computing power of other countries as well? Isn't the goal here for people to work together for mutual benefit? I don't understand why they feel the need to isolate their Canadian initiative, rather than giving Canada the access to computing power far greater than they can acheive on their own.

Experience comes from bad judgment.
Saving up for a "real" supercomputer is a pipe dream. Supercomputers cost several million dollars a year in upkeep, and that's the killer. You might easily get grants to allow a project to use 'x' dollars worth of computing, but nobody is going to approve a capital grant that requires millions each year.
When the University of Toronto did purchase a Cray in the mid-eighties, there was a massive fight. Many felt that the resources to support the Cray were sucking money desperately needed everywhere else. (although, boy, we in meteorology a happy bunch...)

As many of the other posters have pointed out, this work isn't necessarily new, but it is news.
There are other tools out there which do this: Legion, Avaki, Sun Grid Engine, Globus, to name a few but the goal is to create a network of (mostly) supercomputers which doesn't require a lot of reconfiguration at each site. What differentiates this work from many other approaches is that it is transparent to the system administrator.
For those who ask "why can't you just do something let seti@home" the answer is that not all problems in science and business can be easily decomposed into small chunks. Bandwidth requirements and latency may also be a problem. A lot of scientific programmers have to worry about communications much more than about processing power (although this tradeoff has been seesawing backwards and forwards with new advances in both technologies).
There's a worldwide effort through both business and academia to create a number of good, interoperating frameworks for doing this sort of transient, virtualised supercomputer.
Have a look at the Global Grid Forum (which is becoming the focus for Grid computing standards) for more information.
Looks similar to the Grid Computing project from India, announced sometime back ...
See the supercomputer top500.
I think that a year ago or so, the Japanese supercomputer for earthquake simulations had more power than the other top 499 supercomputers combined.
Sure, they'll be able to build a large, loose network of computers, but the access-speed will hardly compare to a single-site computer.

Virtual Laboratory of Eastern Ontario.
The High Performance Computing Virtual Laboratory (HPCVL) was formed by a consortium of four universities located in Eastern Ontario (Carleton University, Queen's University, The Royal Military College of Canada, and the University of Ottawa).
http://www.hpcvl.org/
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.
Yeah, like that isn't the biggest waste of money in the history of science (and that's counting my work)!
Don't worry, the pill cart will be by soon and he'll stopposting to /. for a few hours, calm down a bit after that.
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.
My next sig will be ready soon, but friends can beat the rush!
Screw virtual super computers. Make the equivalant of a beowolf cluster of telescopes!
'Virtual telescope' is world's best
http://cooltech.iafrica.com/technews/167248.htm
Several international teams of astronomers have joined together to create a "virtual telescope" roughly the size of Earth and the most powerful in the world, researchers have announced.
The new array can detect features 3000 times smaller than the finest detail observed by the Hubble Space Telescope.
The virtual telescope was created earlier this year by linking signals from radio telescopes on several continents. Scientists have subsequently found radio signals from galaxies over three billion light years away.

Yeah, I'd love a tax break if I contributed to the goverment's supercomputer through CPU cycles via a distributed client.
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.

Seeing the list of computers that will be used.. IBM SP3s, SP2, Intel/AMD clusters, SGIs, Suns.
Does anybody really thinks they took the time to optimize their code for *all* thoses architectures? I know for a fact that running non-architecture optimized code on those machines is basically a waste of time (this summer I was able to speed up a physics simulation program by a factor 6 only by changing a matrix inversion routine to one using the ibm-written ESSL scientific library on a IBM SP3 machine - the first one was an optimized-for-nothing-lapack-style (non-ATLAS) library)
In the end I think most of this might just be another PR move from another scientist in Canada, trying to get more funds next year.

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.
And, to further show off Canadian innovation, they've developed a new language for this cluster, C eh eh.
Here's an example.

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.

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.

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.
