I believe the latest 2.4 Linux kernels have NUMA support but is it mature or will it get any better? Are other unix OS'es better at taking advantage of NUMA compared to Linux and will this change in a future Linux version?
I've been benchmarking the opteron for the last week, it is at least 26% faster on high mysql load vs a comparably priced opteron system.
Tom's Hardware, Anandtech and aceshardware have all benchmarked the opteron on linux. Tom's hardware's benchmarking isn't that great, aces hardware does the best job.. The Opteron kicked butt in all reviews.
Mine and others.. I've been testing an opteron dual 1.4Ghz vs a xeon 2.4 Ghz by running mysql on them and hammering them. Opteron is around 24% faster and it's not even using all the CPU so it could be much faster in many situations. Yet the opteron CPU is around $10 cheaper. Tom's hardware did a terrible review of the xeon vs opteron, but anandtech & aceshardware did much better tests(espcially aceshardware), both concluded that the opteron was far superior especially when it comes to servers.
And when the 2.6 kernel becomes even more NUMA-aware, the performance will be much better.
There are many reasons why the opteron is just plain better for servers.. wider pipeline, HT interconnect, NUMA architecture. IMO the only reason to get a xeon is because it has been out there longer and you work in a really conservative company.
Our policy is based on the principle that there must be no use of force by China against Taiwan. We deny the right of Beijing to impose its rule on the free Taiwanese people. All issues regarding Taiwan's future must be resolved peacefully and must be agreeable to the people of Taiwan. If China violates these principles and attacks Taiwan, then the United States will respond appropriately in accordance with the Taiwan Relations Act. America will help Taiwan
Bush today:
Determined to quiet what it views as a potentially troubling political storm, Bush dispatched a National Security Council official to Taiwan last week to make clear Washington's opposition to the referendum -- in the process abandoning what this and prior U.S. administrations have called "strategic ambiguity" -- deliberately vague answers about policy toward Taiwan.
I was thinking of that but we're big on SMP machines, FreeBSD doesn't seem to be up to par with linux when it come to SMP. I may be wrong and times may have changed, which would be great, I wouldn't mind jumping ship to FreeBSD.
linux has a ways before it gets to the level of Solaris. If it will ever get there. I've had many weird paging issues with linux that weren't resolved by putting in other VM patches, Solaris never had such problems in the years I've been using it. No one, btw, could answer my questions on the linux kernel mailing list. It's apparantly accepted that the linux kernel grabs a bunch of memory for disk cache and doesn't let go of it even when physical memory becomes scarce. It just swaps like mad even though 30% of the memory is in disk cache and you cannot tune it without hacking the kernel.
Then there's vsar, lockstat..
And the NSA been buying their >100-way smp solaris boxes for years, Linux doesn't have that kind of recognition just yet.
On the upside for linux, you can do what purify does but for free.
So develop on linux, run your servers on solaris may be the best solution.
Read many of the posts here and you'll see that a) groklaw article appears showing ftp.sco.com down b) ftp.sco.com suddenly disappears hours aftwerwards.
It's pretty obvious that SCO's claim is shady at best.
If you're confused, then perhaps you should read it more carefully, others have pointed out why what he said makes sense. I see though that you defend Microsoft with many of your previous posts so it's not surprising that you don't "understand" it.;)
I do this with success. Start out with 100-200 sentences, pick 10 of them at random for your pages, replacing strings with kewords at random to get a certain density. Page rank of 5 still even after they tried to get those evil google spammers.
I don't condone anti-competitive tricks ala Microsoft, sorry you get that impression. Next time don't make such assumptions.
And yeah it would be out of morality, I don't believe in unfair business practices. I would never advertise outsourcers just for my own sake of mind. It's going to happen, you cannot stop the sometimes evilness of market forces, but if it does I won't be a part of it, no thanks.
Oh, and those jobs in your country will go to the lowest bidder, heard Vietnam is now the next outsourcing hotspot. So enjoy the jobs while you can, they'll be gone as soon as you wake up, realize the pollution is getting terrible, create your environmental regulations, rendering your cost of living too expensive.
As the other poster said, yes it could have happened in the U.S. but that person would have been punished. According to my many Indian friends, at least 10 or so, all agree that corruption is rampant in India and they are sick of it. But it still happens too often. It may be a democracy but it is still the third world. The Philipines have the same problem. Same thing in China. This thing could very well happen in India, and if it was a well connected person, they could be immune to prosecution.
If you disagree that corruption is rampant in India then by all means, you don't know India or you do but you lie through your keyboard.
This is due mostly to technology productivity gains, outsourcing included. This translates into higher GDP or output for relatively fewer employees so this is completely expected. Hence the jobless recovery we are experiencing. The question you should ask is: how will this benefit the average voter? Many either don't have a job, have a lower paying job or know of someone close like this. Higher GDP doesn't mean higher utility.
This could have been an Indian, Chinese, whoever.. this is the future where we cannot hold anyone in the third world accountable yet we expect them to handle sensitve information and intellecutal property.
Breaking her silence for the first time, the Pakistani woman who threatened to release UCSF patient files on the Internet says she had "no choice" but to breach the hospital's security after being cut off by the Texas man who'd made her the final link in a long chain of clerical subcontractors.
Lubna Baloch said by e-mail from Karachi that she is "not an opportunistic person who willfully did that to gain some attention."
She said she is instead the "worst sufferer of this situation" because she was only trying to secure UCSF Medical Center's help last month in obtaining money that she was owed.
"I feel violated, helpless," she wrote, adding that she is "the most unluckiest person in this world."
Doctors at U.S. hospitals routinely dictate notes about patient visits, consultations, operations and discharges. Those notes in turn are frequently handed to outside firms that specialize in transcribing them into written form.
The case involving UCSF's patient files represents the nightmare-scenario- come-to-life for the medical industry. For about 20 years, UCSF has farmed out much of its transcription work to a Sausalito company called Transcription Stat.
Transcription Stat outsourced many of the hundreds of files received daily to a network of 15 subcontractors. One of these was a Florida woman named Sonya Newburn, who then outsourced the files yet again to a Texas man named Tom Spires.
Spires outsourced the work one more time to Baloch in Karachi, who agreed to do the transcribing for a small fraction of the amount UCSF originally paid Transcription Stat, thus allowing everyone in the chain to walk away with a modest profit.
But on Oct. 7, Baloch attached two patient files to an e-mail and contacted UCSF. She demanded that the medical facility assist her in squeezing outstanding funds from her employer, Spires.
"Your patient records are out in the open to be exposed, so you better track that person and make him pay my dues or otherwise I will expose all the voice files and patient records of UCSF Parnassus and Mt. Zion campuses on the Internet," Baloch wrote.
Very ironic. Not much we can do, if they want to take advantage of lower living standards and lower taxes due to not having an FDA, EPA, USDA etc etc.. fine!

Darn socialists in the US wanna regulate my wires! :tinfoilhat:
I just fiddle with computers and do what I'm told to do, who knows! :)
It could speed up searching if you can compare 64 bits at a time, so databases should in theory be faster.

Woops meant to say compared to a similarly priced Xeon.. eh I've been testing too much.

This is by far the best review so far IMO:

I heard x86 was god awful, anyone know, has it changed?
Opteron right now offers the best performance for the best price, if they releas a version for that, they could do very very well.
I was thinking of that but we're big on SMP machines, FreeBSD doesn't seem to be up to par with linux when it come to SMP. I may be wrong and times may have changed, which would be great, I wouldn't mind jumping ship to FreeBSD.

After groklaw posted the article & before slashdot posted their article, ftp.sco.com was up, I know because I was able to ftp in. :)
err meant to say groklaw showed that ftp.sco.com was up then somehow it goes out of service afterwards.
Read many of the posts here and you'll see that a) groklaw article appears showing ftp.sco.com down b) ftp.sco.com suddenly disappears hours aftwerwards.
It's pretty obvious that SCO's claim is shady at best.
The upgrade costs money with Tivo, with a freeware program it's free. So over time the freeware option will probably be cheaper.
It's probably cheap because they sell it under cost then recoup the loss and even make profit with the monthly fees.
So you will probably find that it's cheaper if you build your own system, get the listings yourself from the internet and not pay the monthly fees.
If you're confused, then perhaps you should read it more carefully, others have pointed out why what he said makes sense. I see though that you defend Microsoft with many of your previous posts so it's not surprising that you don't "understand" it. ;)
