Bad advice! What you describe is very inefficient memory-wise and does not scale. It is better to load parts of the data set into memory, do as...
Won't scale. Try doing that for tens of billions of data points.
Flat binary files with a fixed record length, and appropriate record length. I.e. Don't waste space and bandwidth with 8 byte doubles unless that...
Effective caching in memory will ALWAYS help. Yes. See this post for information on effective algorithmic improvements:...
But I'll disagree slightly on one point... Your argument is probably only correct for poor designs. Any sensible programmer nowadays designing a...
Yeah you do run a massive quantitative operation. Are you having to prune your list of symbols or calculations to best balance computational...
Nitro, Seeing as you require massive real time efficiency and performance, why not operate a cluster of single or dual CPU machines? You...
A few hours to whip something up using the Matlab sockets package. It won't be efficient and won't scale to more than a few symbols. It is better...
Speaking of Q/A and attention to detail, all motherboard manufacturers, Tyan included, need to document BIOS settings much better. The manual that...
Doh! I missed that. Smart choice.
Iâve attached my timer report. Your quad system probably gets lower overheads due to its higher clock speed. My CPUs run at 1.6 GHz. What CPUs...
The VI Water and Power Authority (WAPA) claims it is 5 to 10 times as expensive to install underground power versus overhead power, per mile. They...
St. Croix is becoming hurricane-resistant after all the storms that hit in the '90s. Buildings are better constructed now. Most have concrete...
Speaking of hurricanes: http://www.gfdl.noaa.gov/~tk/glob_warm_hurr.html http://www.washtimes.com/upi-breaking/20040912-080434-9518r.htm...
Yeah. Speed of prototyping is mainly why we use these tools. Code the performance critical stuff in C anyway. Matlab really needs some kind of...
Incredible! I have always been impressed with QT's richness of features. I developed my original system ideas while trading with QT doing the...
Maybe we can persuade Jerry Medved to write a sockets-based interface to export real time QuoteTracker data into Matlab? That would be extremely...
Experiment with both. Try to code it yourself, and fall back on the built in functions if you need to. Consider using http://www.gloriosia.com/...
Sound recording would be the least intrusive... best chance of success. Of course it would be great if you could capture video or still shots too.
Since this is a free event could you bring a DAT/MP3 recorder and send us an MP3?
