FWIW, the only "major" bank in Scandinavia which requires java applets is AFAIK Danske Bank, and they are set to introduce a java-free banking site sometime this summer.
I don't see how this would be any different if the server would be immersion cooled with mineral oil rather than air; in both cases the waste heat needs to be exchanged to water, and even with immersion cooling you couldn't run the system that much hotter without affecting the reliability of the servers.
AFAIU, yes. (That being said, while I have teached at the university level in Finland, I have no experience of the Finnish primary and high school system from the faculty viewpoint, so you might want to double-check with someone else). Also, consider that there are something like 5 million Finnish speakers, so it's not a particularly large market, so teachers are not exactly going to be overwhelmed by the number of available textbooks. E.g. in physics I think there are about 3-4 book series covering the high school curriculum. I suppose it's a bit different in the US, where one presumably cannot assume a teacher has time to evaluate all the available textbooks. Then again, at least from over here it seems that textbook selection in the US is extremely politicized (can a biology textbook cover evolution? WTF!?) which probably isn't conductive to a good outcome either.
Textbooks must teach to the content of the abitur and the standards being established by the Bologna Process. So, I guess the curricula are well defined. But I'm still surprised that this decision would be left to every teacher individually.
Yes, the Ministry of Education defines (broadly) the curriculum, so it's not like teachers are allowed to teach whatever they fancy. But generally, the large degree of autonomy given to teachers is often seen as one of the reasons why Finland does so well in these PISA tests. Teachers over here are pretty well educated, and it's a well regarded profession. Of course, there are other reasons as well, e.g. Finland is culturally pretty homogeneous and there are quite small socioeconomic differences compared to many other countries. Anyway, it's not like teachers are alone in choosing textbooks, of course they talk with colleagues etc., and professional societies do from time to time publish reviews of the available textbooks, which I assume teachers read carefully.
As an aside, the Bologna process AFAIK covers only higher education (at the polytechnic/university level, bachelor/master/Phd), not high school. Of course, it indirectly covers lower education as well in the sense that it effectively requires that students entering higher education have certain skills.
I think this Finnish group needs someone who is an insider on textbook selection committees to advise them. The last thing these committees want is to embarrass themselves by being seen to recommend a work that was produced in three days. They would lose their credibility, regardless of the quality of the work.
IIRC there are no textbook selection committees in Finland. Teachers are free to choose whichever book they want; or indeed to not choose any book at all and teach the class based on their own material.
- FWIW, Linux finally got rid of the BKL in the 3.0 release or thereabouts.
- Many (most?) 10Gb NIC's are multiqueue, meaning that the interrupt and packet processing load can be spread over multiple cores.
- Linux and presumably other OS'es have mechanisms to switch to polling mode when processing large numbers of incoming network packets.
That being said, your basic points about interrupt latency being an issue still stand, of course.
They are going to have to get their electricity from somewhere & generating capacity don't grow on trees.
Unless they burn, um, err, apples? Yes, APPLES!
- 1. Solve world energy crisis
- 2. Get Nobel peace price
- 3. Profit!!!
Man, I'm awesome!
- No compositing
- Compositing using the 2D XRender interface
Compositing using OpenGL 1.x
- Compositing using OpenGL 2.x
- Compositing using OpenGL ES 2 (code mostly shared with the OpenGL 2.x codepath)
So what is suggested here is to delete support for compositing using OpenGL 1.x.
Personally, I can hardly blame the developer for wanting to prune that list a bit.
And, if you don't want to see this feature deleted, now is your opportunity to step up to the plate and contribute!
What you're looking for is the Green500 list [green500.org]
Indeed, but the site was down when I wrote my previous reply so I had to resort to the top500 list and calculating flops/watt for the few top entries manually.
In any case, as one can see from the list, the best GPU machine manages to beat the K machines by a factor of 1.66, a far cry from the factor of 3-6 you originally claimed. And most GPU machines fall behind the K.
I think the sparc viiifx is quite impressive, it gets very good flops/watt without being a particularly exotic design. Basically it's just a standard OoO CPU with a couple extra FP units and lots of registers clocking at a little lower frequency than usual. No long vectors with scatter/gather memory ops, no GPU's, no low power very slow embedded CPU's like the Blue Genes etc.
I have no knowledge of the design tradeoffs of the individual systems, but I'd say that it's fairly impressive that both the top500 and the Green500 have so many GPUs in the top 10, given that they're both CPU-dominated lists.
Large GPGPU clusters are still a relatively new phenomenon, give it a few years and I suspect you'll see a lot more of them.
