Hey Nitro, I tried to send you a PM over the weekend. Your mailbox was full. Should I try again?

Here is that same contradiction in your argument. If designing profitable systems is “not difficult, not secret, and not worth a premium” then anyone with a bit of money can hire that cheap talent and get rich right? Are we not talking about profitable, low risk, decent size systems? That is...

ROTFL! Where’s your logic on this one? How is automation and rapid prototyping not valuable? You are actually right in a tangential way because my systems aren’t for sale. Are we talking about trading systems? If yes, I don’t see why anyone would plan to sell/give their system code to...

Not in general. You can do everything yourself IF you work smart and design a time-efficient testing architecture. I’m in the same situation as Nitro. I do everything myself thanks to highly automated and efficient testing and trading. In minutes I can write up a script to test 10M unique...

Thanks for your reply. What hardware would you purchase today? New or Used? One can get wholesale lots of older business PCs by the pallet pretty cheap: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=40176&item=5127547318&rd=1 Regarding that mini-ITX cluster, it may be possible to...

That’s what I thought you’d say. I describe how a function/algorithm should work. They write it. Yes, that might help somewhat, but it does not solve the real problem. Using a programmer to write my code may actually take more of my time to explain what to write and check the results than if...

Hi nononsense, Putting asside power consumption, what components do you recommend for maximum performance/cost? Is there a web site that provides good recommendations? I don't mind if the CPUs are 1, 2 or 3 GHz as long as the overall performance/cost is maximized. Thanks.

I thought the DT-12 specs were quite good for $10K. It may actually use less power than my dual Opteron 242.

Nitro and others, What do you think of these: http://radio.weblogs.com/0105910/2004/08/30.html http://www.orionmulti.com/ Are you aware of any alternatives? I'd like to build a 10+ node cluster with any modern x86 processor, only 256 to 512 mb per node, no physical HD per node, boot...

Of course there were also apps that needed the scalability and reliability of unix or mainframe systems, which Windows couldn't do. Like I said, there are examples either way. You just contradicted yourself. Why would any programer able to *actually* produce profitable systems be "easy and cheap...

I find that odd because ten years ago Windows was technically a piece of crap compared to Linux and other Unix or VMS systems, for which Linux was rapidly becoming a credible substitute for. True software talent, the kind needed to build and deploy profitable trading systems is still very hard...

We're not talking about all classes of optimization problems... just ones that apply to market data. My contention is that analysis of market data can almost always be done with a low inter-node communication architecture. Why? Historical and recently received real-time market data is static...

Interesting how we are both 100% confident that our choice (Windows or Linux) is the most cost-saving and time-saving side. We have both invested a lot of time learning these systems, acquired a great deal of admin techniques and the right tools for any problem. We may never agree that the other...

Seems like you run a semi-homogenous group of linux machines with admins who are well experienced. It is non trivial for a user of one machine, who has to devote time to administer that machine, without the extra experience, once they have extensive customizations, hardware specific...

I was merely arguing with your broad generalization that it is difficult and expensive to take systems not designed to run in cluster/parallel and adapt them to such a processing architecture. The transition is trivial where inter-node communication is minimal. Just split the data and/or...

Oh, so you are moving towards an efficient OS-independent cluster implementation. Excellent choice. Now I see why Win XP 64 bit won't work for you. Have you considered developing/executing with the Cygwin libraries+GCC under Win XP 64 bit?

I could never see myself porting over to Linux and spending that kind of time (away from improving my systems) experimenting between distros for an extra ounce of performance gain that is probably at most 20%. There isn't going to be much difference between TCP/IP stack and kernel performance...

Not to interrupt your discussion... but this is one of the reasons I switched to Windows after being a dedicated Linux user for 8 years. Linux was evolving so fast, I ended up spending too much time staying up to date. Tools change. Distributions change. Once I ended up with a nice customized...

There are exceptions on some of those points. IB's real time data is excellent in terms of accuracy, reliability, speed and cost. You'll have to provide your own backfill.
