People, don't be naive and believe that doing things like this at your school, no matter the motive, will be appreciated. Whenever you "lend a hand" or insist that you were "only trying to help" you always get burned. Let the school deal with their own security problems and tend to your education. Its not worth the trouble, trying to help others that don't want your help anyway.
Well if it happened like that, wouldn't it then mean dual core CPU's are even more so vulnerable?
How so? Yet another broad sweep of the inference brush. What does HyperThreading have to do with dual cores? By your logic, all of the big SMP systems are also affected by this, which is simply not the case.
Maybe some people consider intellectual pursuit to be of greater importance (or of greater fulfillment) than getting laid (and later, having to deal with some, likely moronic, person). Ever thought about that, you insensitive clod?
* Please note: I speak as both a man and a woman as I know we both find each other quite moronic
This is interesting, but if what Paul Feyerabend says about the institution of science is true, then this rebellion will be crushed in due time. The dominance of science must prevail!
There is nothing inherent in science or in any other ideology that makes it essentially liberating. Ideologies can deteriorate and become stupid religions... the science of today is very different from the science of 1650... Like the heretics of the Catholic church, Heretics in science are still made to suffer from the 'most severe' sanctions this relatively tolerant civilization has to offer
Fear not for science is the next Catholic church and the ensuing Inquisition will quell this heresy of 'Intellegent Design' and 'Creationist theory'.
You don't need two extra guys. I manage 5 clusters myself on a regular basis. Granted, it would be a hell of a lot of work if I couldn't enlist the help of a few people every once in a while, but for the most part, its a one man job. As well, to the poster claiming that I didn't take into account the cost of storage, I know this thing is nice because of the power requirements and the fact that you don't need a dedicated server room to store it, I'm fairly sure that I roughly addressed that. BTW, we need clusters and none of our researchers has top secret clearance;-P
The theoretical max gives a rough estimate of the raw Floating-point power for all of the processors on the system. You pretty much add up the GFlops potental for each node (not exactly, but pretty much). The sustained and demonstrated GFlops of the cluster is based on the Linpack benchmark. The reason there is such a huge difference between the two numbers can be a result of a few factors. 1) The interconnect is GigE and Linpack tends to make use of Message passing comms which are affected adversely by the latencies produced by the GigE connections (myrinet would have been a good choice, but I suppose it was probably impossible to squeeze that into that case) 2) Memory speeds also are a factor as pushing floating point numbers around involves memory. This cluster isn't using anything fancy when it comes to the memory and I suspect this may be another cause for this.
When they say that this line of clusters can "make or break" Orion, I am right now, leaning for broke. For the cost of this machine, one can get a real cluster with a lot more performance. I know this thing is nice because of the power requirements and the fact that you don't need a dedicated server room to store it, but for $100,000, you can get Microway to build you a pimptacular cluster with Dual-Opteron nodes, high-speed memory and a phat interconnect with either myrinet or infiniband. You will get a lot more work done for the same price.
Sarge would have to go to college and get a degree. You cannot be promoted from a Non-Commissioned rank to an Officer. You can make Warrant officer ranks though they are not the same thing. They stopped promoting NCO's to Officers years ago.
I'm pretty sure that Matlab uses the blas and lapack libraries that are written in good ole Fortran. As well, you are right that Matlab is used for many of the computations being done today. However, Matlab is not a good choice for large memory problems (upwards of 1-2 GB) and generally, problems like these end up in the domain of the beowulf or the classic shared memory system. Often times, much of those codes designed to run on HPC hardware (beo., shmem) are written exclusively in fortran. As well, Matlab is inadequate for long-duration jobs that could easily be parallelized though it does seem to take decent advantage of threads on the sun platform. I heard some people were working on a parallel matlab, but I'm not sure how far that project has come along.
That 3% increase just translated into a days worth of saved time.
21 hours??? Thats about "a days worth of saved time"
0.12 seconds??? Sure, but I wasn't being precise, its still UNNOTICEABLE
11 Months and 20 days??? "maybe save an entire month"
Given that the percentage decrease in run-time was never stated to be constant, I covered my unwillingness to do the calculations with a "maybe". Give me a break.
What was your point again? The point of my post was to show that compiler optimizations are generally better for long duration codes (or codes that are designed to be compiled in a certain way, like video codecs). My point wasn't to sit there with a pen and paper or a calculator for that matter, and give you precise times of completion.
I have done HPC work. You are right and wrong at the same time. Your general assesment that code optimization is a very real advantage is quite true, but mostly when you are dealing with long duration algorithms. Say using -O3 on a simple pi approximator gives you a 3% increase in speed. If it takes 4 seconds to run (or the time for OO to start, I know, ignore the I/O) this 3% increase will account for a loss of.01 seconds, taking you to 3.9. This is completely unnoticeable to the average user, hence optimizations are not all that useful considering the time they add to compilation. However, a certain vasp case takes almost a month to compute on 4 nodes. That 3% increase just translated into a days worth of saved time. What about year long runs? Maybe save an entire month?
My point: heavy optimization: waste for gentoo n00b-user binaries. Only increases compile time yet bears no real benefit. Serious HPC code or even general purpose HPC code, absolutely necessary.
When one is making an effort to attract another demographic, in this case women, one tends to be a little "sexist". You cannot make 50,000,000 products that are appealing to 50,000,000 women. You must make one product that would be appealing to some expected percentage based on some generalization that "most women, because of 'X', will enjoy this game".
And I'm going to go out on a limb here and say that no, not ALL women are the same, but a very large majority of them are. Women in general have not given sufficient feedback to be fully included in a number of areas (esp. gaming). It is a known fact that chicas tend to avoid the hard sciences and mathematics. Is it because big, bad men wont let them in? Or are there broader reasons (for instance, lack of interest in subjects that aren't perceived as "emotionally relevant")?
As such, these trends do not indicate a "defect" in females, but another feature of innate behavior or perhaps an artifact that results from the differences between men and women as they are being raised as children. There are big differences between men and women and it is obvious, that so far, most game companies have done little to encourage women to play. Now that they are, you claim they are sexist fucks for finally making an attempt to be inclusive and you bemoan the site's statistics because they don't include your tastes as favorites in the list. That's the problem with polling, the odd man (or woman) out is always the odd man out. If you have more escoteric tastes that do not follow the trends of your peers, it will appear that you are being left out. But this is not the case.
Ever since I severed my link to the idiot box, I've noticed the changes, as you said, induced by lack of corporate advertising. I have stopped listening to the radio in my car (I only carry CDs) and my TV picks up a couple channels, but has been stuck on PBS and public access for almost 6 months (Tampa has a pretty decent public access scene, asside from the palm-reading, tarot card strangeness). It is really refreshing to not be bombarded by advertising.
I did just watch The Patriot on TBS the other night and was reminded, quite quickly, just how annoying commercial "breaks" are while watching a movie. One can only assume that constant TV/Radio/etc advertising has a more profound affect on the mind than just getting people to buy stuff. Imagine the psychological issues.
The problem is that people who bitch about copyright (i mean total abolition kinda folks) don't produce anything. So saying that they can't copyright won't really affect them.
is that a lot of schools offer nothing in the way of accelerated programs. Some of us go to college with a very good understanding of programming fundamentals, data structures, algorithms and whatnot. It essentially becomes _strictly_ a mathematics curriculum because programming classes are painfully simple, algorithms and data structures, for the most part, can be looked up in a book (or online) and with any skill, implemented painlessly. Even though the only part of the Major I enjoyed was the mathematics, it quickly became boring and stressful because of the constant repetition of simple theorems, greatly prolonged calculus courses (c'mon, you can't condense Calc 1 and Calc 2 at least???), and attending lectures where professors constantly make very bad mistakes, forcing us to just learn much of the material on our own.
That said I left the major because I felt continuing that degree track was not worth the time or the money I was paying. I've already got a well paying job running beowulfs and designing parallel software for problems at the university. I decided that college was not a vocational training facility, but was intended to be a place to facilitate education so I switched to a more "broad" field and put my education in logic to use in the Philosophy department. You may say that it was laziness that prompted that decision but in actuality, I had much deeper personal and ethical reasons for this.
I am already well on the path to reclaiming my old hair color as the stress from constantly doing equations put a few greys in the mix, though it was mostly the tests that freaked me out. My training with proofs has really helped me grasp some of the logical concepts in philosophy and has helped to provide me good insight into induction.
The simple fact is that most people expect CS to be more job-oriented, that they will learn to code and have the skills to walk out and get a $70k a year job right off the bat. CS is still heavily academic but there are too many people in its midst that view it as a vocational training program. I made this mistake and many others, especially those that complain about the math requirements (I don't complain about the requirements, just the methods) are generally those that have this view of the major. Once people stop having this misconception, CS enrollment will likely decline, creating a smaller work force of gifted programmers, scientists and researchers instead of a large base of mostly future Sys admins. That's just my $0.02
Say it with me: Dee-Vor-ack. How many more times will his mindlessness peprspire like greasy sweat to the front page of slashdot before someone gets a clue? Dvorak sucks. But the keymap isn't so bad.
Don't expect everyone to pick up on extremely vague humor, especially when the context of your post was a criticism of the policies put in place by University administration staff. It's always easy to pawn off a slightly ambiguous statement as a "joke" or "sarcasm" when the response is not quite what you had intended, though, I'll give you the benefit of doubt;)
If the 12 year old's parents don't have a the insight to tell their sex-crazed 12 year-old that protection should be used, then they can deal with an extra addition to their family. Of course, they then will get their 12 year old to file with the IRS, get an Earned-Income-Credit form (remember, the 12 year old makes no income to support her child, regardless of dependant claims by her folks), and bilk around $2500 per kid they pop out. The law should state that unless the minor is legally emancipated from the parents, the parents should take legal custody of any child produced by said minor until either a) said minor files for legal emancipation or b) said minor becomes a legal adult. Of course, clauses will be added for special cases.

Perhaps spoken like a virgin, but infact, not.
To speak as a man or a woman does not imply that the person meant to say they were a man and a woman. Your logic needs work.
Maybe some people consider intellectual pursuit to be of greater importance (or of greater fulfillment) than getting laid (and later, having to deal with some, likely moronic, person). Ever thought about that, you insensitive clod?
