OK, does anyone know how well Matlab (7.1 I suppose) is threaded?
Have run some batch files linking 90 simulations in total, which took a few days of continuous running to complete. This is on a 2.x Ghz (Can't remember exactly) P4 at Uni. Could anyone tell me how much better a Kentsfield or dual Clovertowns would run Matlab? (only one application open at once, else its cheating) Would this change between running Matlab under OSX or XP?
Thanks in advance.

Yes, I have. Several times. Things have changed, but the base premise of the article still applies - Microsoft Got Lucky - there is no way to suggest that Apple can pull that off in this day in age when the world depends too much on Microsoft.
Well I think the original argument was not about Apple copying MSs success. I think we all agree that indeed MS got extremely lucky (but also showed a lot of skill and ruthlessness in exploiting that luck). However, the original argument was more about whether Mac OS would enjoy a higher market share if it were open to PCs. It probably would if Apple supported only "certified systems" to avoid driver issues. In any case, it is extremly unlikely that this is going to happen and therefore pure, rather meaningless speculation. :)

So this'll mean one of 3 things.
1) At least 1 Mac Pro will have dual Woodcrests and the rest will have Conroes. Similar to the current PM design.
Different CPU-models in one line of computers? Unlikely. Current PowerMacs have just one type of CPU in 'em, it just happens that one model has two of them.
3) The Mac Pros will all have dual Woodcrests, the MBP & iMac will get Meroms, the MB and Mac mini will stick with the Yonahs. So what will use the Conroes? How about the Apple Mac. A simple box with a Conroe processor, a real replaceable video card, no additional PCI slots (those are reseved for the Pro models), with room for one or two full size HDs, a DVD, wireless, bluetooth, etc...
What I think will happen is that the "MacPro Mini" will have one 16x PCI-E slot, and maybe two PCI-E 8x slots. MacPro would have two 16x PCI-E slots (for dual-graphics), and maybe 3 PCI-E 8x slots. MacPro would also have four drive-bays for HD's (hot-swappable, maybe? (http://forums.macrumors.com/showthread.php?p=2600408#post2600408)), whereas MacPro Mini would have just two. MacPro would be all quad (starting from 2x 2Ghz, through 2x 2.33Ghz to 2x 3Ghz), whereas Mini would be 1x 2.33Ghz and 1x 2.66Ghz.
If they did something like that, I would buy one in a heartbeat. But MacPro would still offer substantial benefits over the Mini, so the people looking at the $1999 MacPro Mini would start to think "why not spend just a bit more, and get a MacPro with all these additional features?". We are already seeing that in iPods :).
Please Apple: You know this makes sense! There are LOTS of people waiting for the MacPro Mini!

Not one but two reactors could be headed for meltdown. U.S. Rushes Coolant to Japan Nuclear Plant to Prevent Meltdown (http://theextinctionprotocol.wordpress.com/2011/03/11/u-s-rushes-coolant-to-japan-nuclear-plant-to-prevent-a-meltdown/). Primary power was lost. A backup generator failed to start. Plant is venting radioactive steam... God, I hope this does not happen.
11.31am: The Associated Press has more details on the state of emergency issued at nuclear plant after its cooling system failed:
Chief cabinet secretary Yukio Edano says the nuclear power plant in Fukushima developed a mechanical failure in the system needed to cool the reactor after it was shut down in Friday's earthquake.
He said the measure was a precaution and there was no radiation leak at the Fukushima No. 1 power plant. He said the facility was not in immediate danger.

Thats pretty bloody serious.... eeeek :eek:

Darn, I am sooooo mad right now. NO LTE iPhone this year! I have to put up with HTC Thunderbolt for a year till iPhone 6. So what tha hell will iPhone 5 have besides dual core? Here is what I think we will get.
1.) A5 dual core (they won't mention speed cuz it will be underclocked)
2.) 8MP (if it fits in Galaxy S II it will fit in iPhone 5) + 1080p Video Recording
3.) HD Facetime (720p, same camera as iPod Touch rear camera) I am really betting this will happen because they put 720p cameras on MBP and promoted as HD Face Time.
4.) NFC Chip (if there is one company that can introduce a new standard, it's Apple)
That's it. You won't see 1gb ram, because you don't need it. Not on iOS, multitasking is very memory efficient. No LTE, as confirmed by this article. Screen size will remain the same, and it will come out June. Why isn't there a leak? Well because iPhone 5 will look identical to iPhone 4. I bet even workers who are assembling it can't tell the difference.

Mag-lev might solve the first loss of energy, but creating a vacuum in front, and behind, the train might be impractical. ;)
You could just build a much larger version of the vacuum system, used by stores in the past, to send internal memos between departments.

Yeah I know. So are you thinking the Dual Clovertown may be a dog 'cause both sets of four cores have to share one bus each? If it won't really run faster what's the point? I hope that isn't going to be a problem for "simple" video compression work which is all I want it for.
FBDIMMs are designed for maximum bandwidth, not for best possible latency, so they cope with this better than any other kind of memory. You may read that bandwidth is the bottleneck for these processors. However, that is only the case for pure copying operations. Code that calls memcpy () on all eight cores simultaneously will run out of steam quite quickly. However, most code does actually do some work with that data (like video compression), and the bandwidth won't be that big a problem.
Lets say you compress a two hour dual layer DVD with Handbrake at 1 Megabit per second. DVD = 9.5 GB takes ages to read from DVD, takes about two seconds to copy in memory. Copying the 1 Megabit takes two dozen microseconds. Most of the action will happen in L2 cache, so you should be fine.

I am so there with the cash ready a willing to fly out the window to Apple's account sooner than Apple can say:
"8-Core Mac Pro Available At the Apple Online Store For Ordering." :)
Yeah, I might do the same.
The only thing that keeps me using my Quad G5 now is the fact Adobe CS2 is not universal and the memory price of the new Mac Pro's are soooo high.
But the octo-core for sure will be faster than the quad G5 for non universal Adobe CS2 apps.
Interesting decision to make.
I'll make my mind when this really happens.

I agree with a previous poster who was longing for a developer kit, and with the recent post about third party addons. This is an exciting aspect to iTV, made possible because it streams its content from the host Mac.
For example, I'd hope they'd put in some simple way to stream the contents of my dashboard with one click onto a transparent overlay onto whatever I'm watching. Heh - check MySpace from the couch.
Wait! Did I say that? I mean, uh...get weather reports. And up to date stock information. Er. Yeah. That's it.

No surprise the iPad is just a fad and people are starting to realize how limited it is. Its frustrating on a lot of cool websites and no file system makes it very limited.
The very second Apple Stores receive shipments of this fad, they're gone. I can't get a fad at the moment because everyone else and their dog buys them before I have a chance.

What's wrong with that? I may not own a particular product but like being in X products forums to learn about it.
in your case 'learning about a product' seems to revolve around telling everyone how misguided they are.
maybe you need to look up the definition of learning.

DRM is a big, fat target for every hacker in the world. I doubt very much it will ever be perfect. It can't be. It would be easy to encrypt music so badly that you couldn't play it. To allow legit users to listen to it means the key is already there. The hacker just finds it.

I thought so. This is the first time I have seen the term "Multi-Threaded Workflow" and I thank you for that.
Yes, I was thinking of your workflow when I said that. :D
I'm glad to see you confirm my suspicion that the 2.33GHz Dual Clovertown Mac Pro will in fact be faster than the 2.66 or 3GHz Dual Woodie when someone knows how they work simultaneously with a set of applications that can use all those cores a lot of the time.
IBM's Blue Gene supercomputer (http://en.wikipedia.org/wiki/Blue_Gene) is fundamentally based on the fact that for parallel tasks you can essentially add all of the "MHz" together, and that lots and lots of slower CPUs will beat a much smaller number of much faster CPUs.
In the case of the current dual and quad core chips, you double the number of cores - but the cores aren't that much slower than the earlier chips. It's a win for lots of workloads, and not much of a loss for a completely single-threaded task.

1. What "punch"? If we're going to use arbitrary words, iPhones beat Android to the "desert". FACT
2. Phone carriers selling Android devices and offering incentives helps the needs of those who do not afford to buy an iPhone but need a smartphone. I fixed it for you.
3. No, they aren't. Please link some sources stating so?
4. Sure, I'll give you that if you want to say it's a ripoff. This is a whole other issue.
5. Sure. It's bound to.
6. That tends to be the way of the Open Source area.
7. I'd hope so. Any competitors selling iPhones should probably be sued, since you know, that'd be a blatant rip off.
8. Sure.
9. Yes, yes and yes.
10. They're really just as bad as Apple's fanboys. I've noticed that the only difference in comments from the huge Apple fanboys and anti Apple fanboys are generally the words "Best" and "Worst" get flip flopped.
1. In terms of marketshare. That's precisely what I meant. It's quite understood. FACT.
2. But android is helping. There's shouldn't be a doubt. Maybe Apple says NO to that because of brand quality OR Apple cannot afford to lose that profit; whatever is the case, android helps with the help of the carriers or vice versa. FACT.
3. HTC's quarterly report. Google it. FACT.
4. But still, its a ripoff. FACT.
5. True FACT.
6. FACT FACT.
7. Again, nitpicking things. FACT is a FACT.
