Yeah, I just found Top500.
It's pretty neat, much better than the older lists. Bookmarked

The very reason some of X related utilities are brain****ed does not mean, Linux crashes.

Infact if such code is sent acrosss, it wont make it in kernel, because its a BAD design and ugly code. Now inspite of all this X is very strongly supported. I seriously doubt, Linux Crashed? If u r configuring beryl(again a hopeless utlitly and i donno why people use it?), only possible thing is ur X will not start, but LINUX wont crash? Because, it dont restarts and it doesn't have BSOD. yeah it may be infintely trying to recollect resources from BrainFu(ked binary only driver.


Stock Exchange Servers:
Few of my Friends have worked for GLtrade, one of the biggest trading companies, globally. Such companies use AIX, HP-Ux, Free and Open BSDs, they dont even use Linux, why? because of scalibility issues, forget anything else. I once went to see some indian stock company's servers, even they use Aix and Linux for their servers, the reason they use Linux and not BSD, is because they are not that big so to use BSD systems.
companies like NYSE and Nasdaq using anything other than BSDs or AIX or SVRs for their stock servers is highly unlikely, may be they are using windoz for user displays and all, but backend server running anything less than a BSD, highly unlikely.
anyway NYSE uses HP-UX for the real work.
Nasdaq is using some customised unix for internal stuff, for monitoring and display some NT based system.

Did you mean the Dawning system christened the Magic Cube?

Do not be fooled by the one running Windows:
http://tyan.com/newsroom_pressroom_detail.aspx?id=1289

The press release above says that the top Windows system in the Top500 is dual-boot. Oddly enough, other press releases leave this detail out. What does it actually run most of the time?

Do not trust secondary sites.
Go to the site and check.

You need to recheck your facts before penning it down.
It supports Lustre filesystem, and my limited knowledge shows Lustre does not run on Windows.
Plus they upgraded to 2.6.18 kernel. Now how on earth did they run windows HPC with earlier 2.6.9 kernel. lols

Forget it, it is pure M$ marketing BS, which I was initially criticizing.

And who sent you to fluxbox?
Atleast give him some reps you thankless chirkut .

What you think doesnt necessarily means that correct. You think Beryl shouldnt crash the OS, sounds logical, but the exactly happened. BTW those f*&*ing applications are the cause for all the Windows Crashes. If not apps, the drivers.

Now coming to the Trade Market, the names I took actually store live data in SQL. If SQL runs on BSD/UNIX then they might be using non Windows-OS. I know because I have worked with a specific on-site PFE regarding slow performance. Which turned out to be due to bad query design.

BTW your statement "companies like NYSE and Nasdaq using anything other than BSDs or AIX or SVRs for their stock servers is highly unlikely, may be they are using windoz for user displays and all, but backend server running anything less than a BSD, highly unlikely."

clearly says that you have developed a perception based on Microsoft's past history (not Window's past).

^ if you have a documented proof of the said stock exchanges running windows on main transaction processing server, please cite. look forward to it. thanks.

our perceptions are based on Microsoft' DNA.

>>>>What you think doesnt necessarily means that correct.
I "think"?? no, i dont, i work on kernels, so I know and not "think",.and i dont talk abt "think", i talk about what i know
>>>You think Beryl shouldnt crash the OS, sounds logical, but the exactly happened.
Beryl wont crash OS, It may crash X. show me a kernel dump, if at all it crashed OS. if there is no kernel dump, it never crashed.

>>>BTW those f*&*ing applications are the cause for all the Windows Crashes. If not apps, the drivers.
Drivers are part of kernel and if their drivers are bad, then OS design in bad. Because driver model is part of kernel subsystem.

>>>Now coming to the Trade Market, the names I took actually store live data in SQL. If SQL runs on BSD/UNIX then they might be using non Windows-OS. I know because I have worked with a specific on-site PFE regarding slow performance. Which turned out to be due to bad query design.

sorry did i miss something, What is the point you are trying to make?

>>>BTW your statement "Bla bla"
clearly says that you have developed a perception based on Microsoft's past history (not Window's past).[/QUOTE]

I hardly care about M$ history, all i care is good OS design(open to all techs and OSes), show me the correct fact , i will be happy. Please put some data, report, analysis, supporting your statement. I dont talk about perceptions here.

[das_vicky]

@rpm19050 -> I dont think that was valid thing to ask. if someone says he has worked with Nasdaq, and you are questioning him, its questioning the intergrity. Anyways here it is
Microsoft Case Studies: NASDAQ Stock Market, Inc.

@initpidzero -> I understand that Drivers are kernel mode, but i do not understand how the drivers being bad, translate to OS design being bad. So you go ahead and develop a Driver (buggy) and crashes in Kernel mode, you still think the problem;s with OS kernel and not the Graphics driver/Intel WIFI driver's ?? (gave these exacmples as they are most common cause)

>>>sorry did i miss something, What is the point you are trying to make?
Yes, your thought about "NASDAQ's" and NYSE's use of SQL and Windows as OLTP backends for realtime operations being "highly unlikely", is absolutely wrong. They do use Windows Platform and they have migrated from NON-windows Platforms.

>>>Please put some data, report, analysis, supporting your statement. I dont talk about perceptions here.

if you talk only about facts, then where are the facts that NASDAQ etc. etc do not use Windows platforms, where is the data and report, analysis?

[ManISinJpr]

^^ Bhaisahab, you have proved what you were saying all along. after reading this I am spellbound.
If Nasdaq is not mission critical then what is? Billions and Trillions of $$$$ and they rely on MS...amazing piece of info there.
Repped !! with humble graciousness.

[Aragorn]

Hey das_vicky ... really great insights from you .. you have really given us some great info here .. repped .. and keep the good work comin ..

[initpidzero]

yes, u r free to write shytty drivers, offcourse, but those drivers making to official kernel, "unlikely".
Plus when u write a driver, u r suppose to follow a standard practice, so if ur standard practice is retarded, then u are bound to get Fu(ked up drivers. example, e1000 driver submitted by intel is entirely re-written for Linux and then only it made an entry to official kernel, and it still have some issues because of buggy hardware and not beccause of buggy software.

AFA NYSE goes, it uses RHEL5, here is the link:
NYSE builds global trading platform on Red Hat Linux

And abt Nasdaq, I am not able to find any link abt their OS, other than one u suggested, let me dig a more.
