To my pleasant surprise, many people reacted with a similar comment. Actually one of the main drivers of the whole HPC project was that we , unlike most departments having clusters, were not going to keep it for ourselves. Posts like yours just confirm what we expected, many people have more cycles that they can use, and even more need more cycles than that they have. The main obstacle is organizing the sharing...
One idea we had is that instead of direct payment, we ask people who use it to donate a node or two to the cluster. Keeps growing and becomes a shared resource. Lets hope it works.
I normally don't feed trolls, but what the heck. Please check your facts on Java performance, for example : http://kano.net/javabench/data
Plus, we have more than half a million of lines of code, which for a relatively small group like ours is huge, so we cannot "just rewrite"... And, it is a mixed platform cluster. There are/will be all sorts of machines running inside, so java makes life easy...
It is just sad how many readers jump straight on the meme of java=slow. Sure, 10 years ago that was the case. Have you ever actually used java to do some heavy lifting ? Try 1.6 and see...
If your code is not doing something awfully specialized like massive matrix inversions and pure floating point calculations, and you dont care about startup times ( our simulation runs are many thousand times longer that the startup) there is very little difference is speed. A massive difference in development cost though. Plus basically ALL agent based modeling platforms are written in java. I wonder why...
Interesting. This is exactly the kind of things we had in mind. It is usually a organizational issue, not a technical one. We are thinking about charging for access by making people buy/donate new nodes, effectively making it better for everyone involved.
You are missing the point. Most, if not all people who work here are domain experts, not programmers. I will gladly take a 30 % performance hit, but still allow the experts to write something useful, in a realatively clean and simple language that will scale nicely. Plus, the amount of scientific libraries for java is insane. And if you are interested in performance, check out hadoop : http://hadoop.apache.org/core/, i is written in java, mind you....
Dude, Im not asking what research to do on this thing. I got plenty of it. But, as other people also mentioned, these kind of machines can stand idle for periods of time. Im just thinking about interesting things to do then, and not waste the downtime completely...
Look, we have PLENtY of ideas, that is not the problem. But sometimes it is good to go far out on a limb and see what selse you did not think of. And do not underestimate the power of java. Plus, I prefer to spend one extra day crunching through less optimal code , then weeks and weeks of peoples time, who cant really program that well, optimizing the same code. Plus, readability/maintainability of java code beats speed in importance any day....
Actually, we are designing a sophisticated monitoring and control system that will power down all the nodes that have nothing to do. Sustainability is *the* reason why we build models in the first place. Most of them are used to estimate CO2 emissions of different future industrial systems.. so yeas, you are right, this is an important issue...
Everybody always whines about the lack of linux games. We all know how much effort it takes to write a game, especially a good one. Now here is a company offering something that looks fairly decent, and includes a very minimal and polite way to ensure you actually payed for it. First thing everybody says, no I will not buy it, since it requires me to prove that I bought it ?? WTF ?? Are we really surprised there are not many commercial quality games out there ?
If you want linux games, you either make your own/help people make them, or you pay for them. It is that simple. Im buying this one when it is out of beta, just as I preferably buy hardware that has good vendor supplied OS drivers for them. Vote with your valet.
All Nikon DSLRs have the setting to write a custom text to the exif comment field. for example : "(c) www.myname.com" is what I do. If you happen to have one, check these instructions for the D200 : http://www.kenrockwell.com/nikon/d200/users-guide/menus-setup.htm#secret They are pretty similar for all nikons.

Very interesting, thank you. I will certainly look into this !

Its in Europe, the Netherlands. If you are still interested, do you have an email I can contact you at ?

Great idea. This is exactly in the line of whaty we were thinking. Send me a slashmail, and we can talk....
Well, no so sure, check Hadoop out : http://hadoop.apache.org/core/
Yep, it is written in Java...

When the pressure is low, solid water will not go through liquid phase when the temperature increases. Basic thermodynamics...
See this : http://www.cbu.edu/~mcondren/water-phase-diagram.jpg
Choose a sufficiently low pressure, and draw a horizontal line (increase in temperature) from solid to gas...
