Linux trading platform
It looks like someone wants to create another USS Yorktown case, trying to blame operating system for a linux trading platform of 3rd party application. In case linux trading platform Yorktown, Windows NT didn't cause any problems - yet most people believe it did, due to cleverly written Wired article and personal beliefs of a middle-level management person with no technical knowledge and no technical involvement with the project.
Posted Jan 21, For customers this huge and opportunities this lucrative you can bet that Microsoft put a crapload of effort into getting this system up and running efficiently. LSE used all the star Microsoft technologies linux trading platform were available at the time: I don't know how much anybody here has dealt with Microsoft, but if your a company deploying Microsoft solutions they will actually be devote quite a bit time to you.
Have their engineers work with your software guys to port software and will even fly people out to work with you. And that is just for a relatively small company. For something like the LSE you can definitely bet linux trading platform Microsoft pretty much had linux trading platform employees devoted nearly full time specifically to making that work.
Both with the software developers and the administrators who deployed it. This is actually one of the nice points about Microsoft. If your using their stuff and your running into problems they are not going to let you twist in the wind; as long as your a big enough customer of course. Hmm, no, can't be. Must be another giant conspiracy.
Posted Jan 22, 1: Hate to be the one to break this to you, but Microsoft was heavily involved in all aspects of the LSE. Posted Jan 22, Posted Jan 24, One era CIO said "[our supplier forced us to switch to Linux and] we found we had an additional overhead in understanding the technology and the total cost of ownership has risen.
LWN tries to be factual, and unbiased. Posted Jan 28, And it succeeds, in both cases; not only in the articles, but also, for the most part, in the comment threads. And part of the reason it succeeds in comment threads is the variety views represented by the commenters. There are two sides to every story, and in LWN, you will usually see the 'other' side presented fairly somewhere in the comments even in stories involving companies viewed by most of the community as linux trading platform guys', such as Microsoftif only sometimes by a devil's advocate in order to spark informed discussion.
This is a good thing: Anyway, the point of this is that accusing anyone who posts a comment in support linux trading platform Microsoft of 'astroturfing' i.
Having all sides of the story represented is a good thing, even the sides you don't happen to agree with. As for the restarts - there are many Linux systems out there that are restarted daily for exactly the same reason. If you could point me linux trading platform some such systems I'd be curious to see what kind of setup they are running.
Posted Jan 22, 8: Posted Jan 24, 0: I suspect that you may be mistaken in your original claim, and are therefore unable to provide substantiation.
Linux is used on a wide range of architectures, including supercomputers that require very high availability, and its uptime can be measured in years. I can find no evidence that Linux either suffers systemic file corruption in XFS, or from memory leaks that mandate a daily reboot. If you could point me to such systems, I'd be curious to see what kind of setup they are running.
Posted Jan 24, 2: I really wish my workplace weren't MS 'partners'. Posted Jan 25, However, I actually can give you one company name, because they talked about this in public. One problem they had was that XFS was losing files. Just like that - something didn't quite work and the file was gone. It wasn't really a problem for them, because they had everything replicated, so were able to work around that linux trading platform automated manner.
What I'm trying to say is, both systems work OK for most people. But for some they don't, requiring restarts. Posted Jan 23, My apologies to everyone else for feeding the troll, sometimes I just can't resist. London Stock Exchange begins migration to Linux-based trading platform ComputerworldUK It looks like someone wants to create another USS Yorktown case, trying to blame operating system for a failure of 3rd party application.
Also, linux trading platform want to improve speed for real-time trades, which the new platform apparently delivers as well, linux trading platform no mention of MS Windows.
What they did - and what is happening here - was constantly highlighting the operating system the software was running under. Same thing in this case here - nobody remembers who made the previous platform, and who makes the new one, but everyone remembers that the faulty one was running under Windows, and the new one runs on Linux.
Most of the companies involved could easily get support from Microsoft. There is nothing Microsoft can do if the company employs a bunch of morons. It doesn't tell you how much real involvement Microsoft technical people had with the project. It might just as well mean that some marketing guy from Redmond played golf with the Accenture project manager who linux trading platform then sound good to his boss by saying he got special help from Microsoft.
Even if their only involvement was to spend 5 minutes writing a press release linux trading platform credit for the work, it is still their fault when it fails, just as it would be to linux trading platform credit had it succeeded. Regardless of middleware some of this is attributable to the underlying OS. Even if you disregard the latency one of the prime issues cited by the LSE was that the windows based systems needed to be restarted rather frequently, in some cases more than once a day and one report mentioned a restart during trading hours which is a HUGE no no that stalled trading for 5 linux trading platformthe NASDAQ system handles 24 hour trading with trade completions in less than 1 second in most cases and no trades that don't execute in less than 2 seconds from receipt of order.
Another seems to just leak memory somewhere. So, in case XFS makes you, or anyone else, a trouble you can migrate to something else. In case of Windows, your only option is FAT In other words, he was politely asking linux trading platform to substantiate your claim.
You have made vague allusions to "filesystem corruption" and "memory leaks", but have not actually cited concrete evidence of such things.
What do you expect me to say, company names? Also, by claiming that Linux is used in a mission-critical environments running without reboot for years, you seem to believe that it's somewhat different from Windows. It's not - Windows is being used in mission-critical environments as well, including military ones. And, believe it or not, it doesn't need daily reboots either. There is a huge difference between typical business applications and the sort of 'soft realtime' performance that things like the stock exchange programs and telephony demand.
They require the ability to have not only low-latency, but deterministic latency. Having the ability to linux trading platform latency like that is completely and totally unneeded for linux trading platform server setups. Linux trading platform fact having the OS even capable of doing this leads to lower efficiency and lower overall performance.
It runs counter to the sort of typical loads that a server needs to support. If you were to take typical benchmarks meant to gauge the performance of realistic application load on a system I would bet that those benchmarks would score lower on the Linux stuff used in the time sensitive portions of a stock market linux trading platform if you just used a off the shelf Linux version from Redhat or Suse.
You are absolutely right that application developer can ruin any performance, but in this sort of situation the OS and the middle ware choices absolutely matters. It's critical, in fact. Also the ability to have Linux be successfully customized for a specific purpose does not really reflect on how well it can meet the linux trading platform of typical business usage.
I notice you tried unsuccessfully linux trading platform argue something similar on wikipedia. As they rightly told you there, all the verifiable evidence strongly implicates Windows NT as the source of the problems with the USS Yorktown, so if you have any evidence proving otherwise you should provide it.
If there was, the Wired author would linux trading platform about Windows NT malfunction. Given that the whole Wired article was based around the "Windows NT sunk the ship" story after all, how many Wired readers would care about a bug in some proprietary navy software they never heard about? The exact cause of the problem is already known - missing NULL linux trading platform in the application that This missing check caused linux trading platform application to crash.
The only connection between this application and Windows was that it was running under Windows. It wasn't part of Windows, and it wasn't written by Microsoft. In every corporation you will find dozens of people that believe Linux is bad and you shouldn't use it linux trading platform critical parts of infrastructure.
Exactly the same level of "technical insight".
