  4. Get More Creative with AWS on Ask Slashdot: Clusters On the Cheap? · · Score: 1

    I see a lot of people suggesting the use of cluster instances on AWS. At first blush this is what they are built for, but it's not a gimme that they are the most cost-efficient option. From the description, the job is not targeting GPU, and it's also not network-bound. Some of the high-cpu instances are more economical if you don't need the gobs of RAM or 10 Gigabit pipes. The cluster instances do have somewhat faster CPUs.

    AWS offers a MapReduce layer that supports all of these instance types (http://aws.amazon.com/elasticmapreduce/).

    Cluster xLarge (GPU) = $2.10 / hour = $0.26 / hour / core = $0.063 / hour / cpu unit
    Cluster xLarge = $1.60 / hour = $0.20 / hour / core = $0.048 / hour / cpu unit
    High CPU - medium = $0.17 / hour = $0.085 / hour / core = $0.034 / hour / cpu unit
    High CPU - large = $0.68 / hour = $0.085 / hour / core = $0.034 / hour / cpu unit

    Throw in:

    * Spot instances are discounted by over 50%. If your jobs can work on a range of instances, bid on a variety of cheap CPUs first.

    * Reserved instances come out ahead after about 6 months of 24/7 usage, if you're going to use it that way.

    All together, you could do something like this, with many possible variation. This gets you roughly 10 CPUs running 24/7 for 6 months, plus 3 hours a day of cluster compute time. And of course you don't pay for any time that you're not running so that could be reallocated.

    5000 hours High CPU (medium) = $850 = 10,000 CPU hours
    5000 hours High CPU (large) = $3400 = 40,000 CPU hours
    250 hours spot instance (Cluster) = $150 = 2,000 CPU+ hours
    250 hours spot instance (Cluster GPU) = $200 = 2,000 CPU+ hours
    ---
    Roughly 55,000 CPU hours for $4500, leaving about $1800 for bandwidth, storage, or more compute time.

    Point being, just like you can customize the heck out of box to buy, you can carefully craft a cloud approach more efficiently that just buying cluster time. If you just throw it at GPU cluster boxes, you could get half the work done (or less)...

    Really?

    Hauling in a truck-load of fuel, to move 400 lbs of water, to supply a few soldiers for a day or two, is going to kill FAR more people than just having someone transport supplies to those soldiers by traditional means, or avoiding putting those soldiers so far out there in the first place that they get cut off.

    3) If you're afraid of risking more soldiers, why are you willing to send them on manned delivery runs, but afraid of the risk of them trucking in fuel 1000 miles away?

    And besides lives, you have all kinds of questions of COST, MAINTENANCE, RELIABILITY, etc. If one of these ridiculously low-capacity supply planes means that a dozen Humvees don't get armor because of cost or lack of manpower, then you're making an incredibly stupid mistake.


    Well no shit maintenance is an issue. And it's not with Humvees? And who said we were going to make dumb ass judgements on when to use these and when to spend on something else? That's just an assumption based on the idea that they are useless. A bit of a self-fulfilling argument.

    I am not sure global warming is inevitable. But if all we do is conserve, it will be. Conservation can't delay enough to matter or mitigate the disasters enough to notice. Massive conservation may be enough to allow some solutions to work, but even then, most solutions will work without it just as easily. It is not a solution, it is a distraction.

    Agree: conservation alone is not enough
    Disagree: it's so worthless that it is actually more of a hindrance than a help

    Granted, if we as a society treat conservation as the solution, we're screwed. But that doesn't exclude it from the equation, IMO.

    And so far it has distracted us so completely that when a hint of a solution is mentioned, even from someone as respected as Dyson, it is dismissed without discussion. That said, dealing with global warming, without much more info than we now have, would be problematic, on the scale of the Great Depression + WW2, or perhaps the collapse of Rome, only worldwide. A big deal to be sure.

    The problem is that Dyson doesn't *have* even a hint of a solution. What kills me is that someone like Dyson can play the ever-so-appealing "heretic" card and suddenly he's a rogue genius who can dismiss all of the world's climatologists out of hand. But then if we question HIS ideas, we're stifling discussion. His right to discuss these issues in unquestionable. Why we should stop and treat him on equal footing with the scores of people more qualified is mind-boggling to me. It's better than reading the latest political pundit spewing his own personal opinion on the matter, but not much.

    It would take longer to ram this through just the Senate. That is statistical noise. And no, you don't have to wait 15 years for any benefit, 2 months is the sum of all benefits accumulated over those 15 years.

It's just that you say the cost is no less than the benefit, and I believe the ratio is far more favorable than that.

    There are actually plenty of good reasons for conservation, save money, don't destroy resources needlessly, save forests, etc. It is just that Global Warming is not one of them.

We don't have them. This assumes that global warming is inevitable.

    Well I guess that reveals where you are coming from on this. Global warming is inevitable, so let's learn to live with it and forget trying to avoid it. We'll just chase the weather around... become a migrant species. That'll go smoothly. That's not just a little assumption, that's wishful thinking.

    Ditto my last paragraph. Also, this is mostly overblown FUD. Billions die? Only if you chain them to their houses now and wait the 20-50 years that it would take for sea levels to rise. Hundreds of thousands I could buy, maby even a few million in floods etc, But people aren't stupid enough to say 'ten years ago the water was up to my knees and I stayed. five years ago it was up to my waist and I still stayed. last year it was up to my neck and I stayed. this year it is over my head and damn it all I am still going to stay!' Far more (millions) could/would die in the massive refugee crisis that would ensue with a 50-100 foot rise in sea levels, especially if nations block their borders like they tend to do, but to imply that billions could die is just plain stupid.

    Well look, I'm willing to go with "millions". But there is no doubt it would be a huge disaster, quite likely the largest in human history. It's not long until the world population will exceed 10 billion. And over 50% of that lives in coastal areas. A billion people might not die, but a billion could easily be uprooted, and the domino effect would be ghastly.

    Don't be daft. Worldwide transportation is only 14%

    I'm not being daft. The principle doesn't just apply to 10% / 90%. It can also be 1% causing 5% of the problem, or 5% causing 10%. But let's move on- I think we probably both understand the principle, but disagree about the costs involved in this application.

    A quick look at the number of cars in the US and the total production rates of cars shows that it will take at least 15 years to replace the US auto fleet with your doubled mileage cars. Assume that trains, etc. take that long too. (they will take longer, but K.I.S.S)

    From this we learn that current rates of CO2 emissions are rising in excess of 3% per year. Congradulations! The almost impossible task of cutting fuel use in the US by half gains us about 7 months. And it only took 15 years to get there!

    Big flippin' deal. We could gain almost 3 times that by trapping half the CO2 and methane released into the air during oil and natural gas extraction. We could do that in much less than 15 years, and it would likely be cheaper. And both wouldn't be near enough - they would still hardly matter.

    1) Replacing all of the cars in 15 years... what, we reap no benefit until every car is replaced? Even in 5 years there would be a significant turnover... how many new cars will be put on the road in that time?

    2) 2% of oil IS a huge flippin deal. Yeah, if I had to choose fuel economy or addressing the other 86%, I'd choose the 86% every time. But they aren't even remotely exclusive of each other. The thing about fuel economy is that's it trivial to improve. All of the technology already exists, and is IN PRODUCTION. The result might be 2%, but the effort is much less.

    Look, you're trying to hang me up on this fuel economy thing. I never said it's the #1 issue. It's not. We could stop driving cars altogether and I realize that it would only make a dent in the problem. This is true. I think where we disagree is the cost, and the idea that it would less

We would too. Getting there would be a problem. "Somewhere else it might get colder and kill all the crops." Only a problem if we are still planting there. Which we wouldn't once we found out it was too cold there and went somewhere else. And there would be somewhere else to go.

    * Sure it will level off "sometime", but that sometime is WAY beyond 1-3C. That was my point. If we burn all of the oil and coal on the planet in the next century, it's not gonna be a 1-3C hit. Not even close.

    2) "the US doesn't have to implement the world's worst fuel economy standards, right?" of course not. We have to implement the renewable/nuclear produced fuel economy as the standard. This is because within 50 years (probably sooner) there will not be enough oil at any price to use as fuel. Even if we had unlimited supplies, better fuel economy is almost pointless. Even a 90% improvement in fuel economy would only slow down the rate we cause global warming - we would need to stop it, since in this scenario your overblown fearmongering "it's going to keep going up" would be the case. And to stop cutting down the rainforests will require expensive changes - just taking away the axes won't solve the problem. (Not that we don't have to do this eventually anyway...this is not really a global warming issue)

    We agree that fuel economy standards are not the solution. Where we don't agree is that we shouldn't take positive steps to slow down the problem while we work on the solution. Slowing down the rate of global warming is a big deal. What if we buy ourselves an extra 5, 10 years to work on a solution? That's a long time in technology terms, and a lot is at stake.

    How can something be pointless if the benefits greatly outweigh the costs? What exactly are we gaining by having gas guzzling SUVs?

    Fearmongering that "it's going to keep going up"? Do you honestly think that humans can only raise the global temperature another degree or two, and then that's it... it will just stop going up? We've maxed out our damage?

Somewhere else it might get colder and kill all the crops.
