At Rice University we have a Java version of Nachos. Of course, not all of our assignments are done using the Java version, since it is an OS after all.
This could patroll newsgroups and/or forums, and have the FAQ for that forum/newsgroup, it could read messages, decide if that message is asking a question which is answered in the FAQ, and then autmatically answers the persons question.
this would be nice since most forums I've been in have people asking the same questions over and over, and people tire of answering them, so sometimes they dont bother after a while.
doubling the processors does not, in most cases, double performance. Its a very very complicated thing trying to split up tasks between two processors. Sometimes its easy, you can have word running on one CPU while excel runs on the other, no problem.
But say your playing an MP3, how to split that task up among 2 processors? probably doable, but your code would most likely need to assume 2 processors to get anywhere near double the performance. Which means single processor users are out of luck, unless you have TWO code bases. Some problems just CANT be split up between two processors with any significant improvement.
So in general, making one CPU faster is the far better option . Its cheaper too.
Whats your point? I dont understand why this upsets you....
its not a marketing PLOY. AMD isnt being dishonest, they didnt say they were coming out with this thing tomorrow. All they said, and all the demo implies, is look, here we are, we smacked out a 1.1Ghsz chip. Well be refining out process and making more of these, selling them so, so invest in us, stick with us, we are pretty good.
whats the problem? Nobody with half a brain is being misled by this demo in ANY way. when was the last time you head of a chip being demoed at X mhz and not actually seeing them in the store within a year?
calm down guys =)

Engineers fix things that whirr and humm? not always
Engineer use their hands, not always.
I think that a EE working on a big chunk of a VLSI project, if he died, it would be really hard for someone to step in and pick up where he left off, at least just as hard as someone picking up on Mozilla or other software project.
discrete vs. continous math? well even yourself says (primarly) because both you and I know very well there are cases where CS peeps deal with continous, and times that 'engineers' deal with discrete.
From a social point of view, there is no elitist distinction (here anyway) between the science/engineering/computer science students at all. Its us vs. the 'academs'. There are no fraternities AT ALL, but we 'non academs' all sorta lump ourselves in the same category.
I think what we have to remember here is that ENGINEER is a name, a word. Words evolve, their meanings change to fit the times. At once time, engineers solely built things out of wood, big machines. When people started mixing chemicals and calling themselves chemical engineers, the wood/steel construction boys probably giggled. Then people start engineering things solely out of NAND gates, and call themselves electrical engineers, hahaha, but they dont use their HANDS or do stress tests, haha, they arent engineers. Thent he computer science boys come along and make things COMPLETELY in an abstract sense, with no real existence in the physical world. So we arent engineers.
Cache. A big load of on die cache possibly supplemented by a bigger load of not on die cache.
The other answer is DDR ram, so you can jump from PC 133, to PC266 memory, wooha!
yes, memory speed is a problem in PC world, but still, upping the MHZ is a good thing, especialyy when you have a sizable cache to work with. Remember back in the days when computer had a mere 640k of memory in TOTAL to work with? Well now we have about the much in cache running at the SAME SPEED as the processor =) which aint such a bad situation really. Clearly a large set of problems can be solved by code that almost totally fits in cache.
1. a real world benchmark with your favorite applications
2. The SPEC series of benchmarks. even these arent perfect, (people have been known to unfairly optimize for some of the benchmarks from time to time) but they are pretty good, and a much better measure than how many gigaflops (a number which can be EXTREMELY meaningless) a processor can do under some contrived situation (lets divide 2 by 1.0 a billion times!)
Last I checked the SPEC, the PowerPCs had slightly better scores than an Intel P2 in integer performance at the same Mhz (and I do mean slightly) integer applications. In floating point the P2 was faster, again, slightly.
So basically Mhz per Mhz, it depends which one will be faster.
Now the Athlon is faster than a similarly clocked and cached Intel chip at everything. I havent checked the SPEC marks on Athlon vs the latest G4 marks, but I bet it does just fine.
its a public demonstration that their facility can and will produce 1.1Ghsz chips, and they have demonstrated this before Intel has.
confidence in the minds of the industry is the key to AMDs survival. OEMS, shareholders, consumers, etc. all need to believe that AMD is da bomb, or they wont trust AMD and go with tried and true Intel.
told us what an engineer is NOT why dont you tell us what one IS? hmm?
I'm curious as to your clearly firm conviction, and to know why you give a damn.
well if your going to define engineer in terms of

then in most schools, graduating computer scientists are in fact in the engineering department, and hence engineers.
basically your distinction is a stupid semantic one.
there are many kinds of engineers that do many kinds of things. The only commonality between them is they *tend* to *make* things and know a good bit of math.
carmack makes things, and knows a good bit of math.
woohoo hes an engineer, using a slightly less stupid semantic distinction with some basis in practical reality.
I dont think a slashdot forum is really the place where this topic can be discussed appropriately =)
but for fun you can consider a person who was never taught a langauge. Do you think there is any way they can ever form some of the higher order concepts that we can?
I dont personally think that language has a huge impact on how we think, but there are definitely some subtle impacts.
I'm not sure that what linguists think in general has any influence on what the truth actually is =)
as one currently wrapped warmly in the womb of academia, I can gaurantee that in many disciplines, the idea that language directs what and how we think to some degree is VERY much alive =o and of course open to debate.

they are rapdidly approaching the big boys, and price is remaining constant, with the top of the line cards hovering around 250-300 at any given moment =) rule!
Slashdot Mirror
by Motorolla, but they insisted on mandatory drug testing.
so I told them no thanks.
really, does it bother anyone else that a company even has the ability to require people to piss in a cup for them?
you could get more CPU power for less with a bunch of 1GHZ athlons running Linux.
and NO, a PS2 does not have 15 times more graphical power than a normal PC 3d card.
that article is clueless.

is it all set up to handle openGl? can it be ported to linux/mac/pc no problem?
is it REALLY as fast?
