i'm working on application heavy number crunching. intended run on single computer. recently, we've started looking @ multithreading speed calculations. of algorithms can made run parallel without effort, , use fixed thread pool run each of sub tasks. what wondering is: how number of threads (the size of pool), typically specified these kinds of algorithms? suspect typically done using either configuration file, or commandline parameter, haven't seen examples that, wondering if there better ways. related this: relevant specify number of threads? thinking setting pool size number of assignable cores run fastest, thread-contention processing power in case of on assignment relevant performance? eg: setting 20 max threads on 4 core machine worse setting 4 max threads? edit: application intended sale, have no idea computers run on. i'm looking general guidelines, , best practices. a rule of thumb use number_of_cores + 1 threads (certain parallel build sy...

basically, application has zedgraph plot, curve loaded. intrinsically (i.e. in database curve points stored x-y pairs), each point's x-value double represents time (in seconds) has elapsed particular point variable datetime initialtime, 'december 15, 2005 12:45:02pm'. i give user option of displaying x-axis 'relative time' (time elapsed since initialtime original values) or 'actual time' (full date/time of each point). currently, every time user switches time views, have iterate through each pointpair on pointpairlist of curve , translate x-values to/from original values , zedgraphs xdate format. is there way more efficiently? thinking changing zgc.graphpane.xaxis.scale.format in way such accounts translation, couldn't find anything. i thinking changing zgc.graphpane.xaxis.scale.format could change axis labels under zgc.graphpane.xaxis.scale.textlabels (which array of strings)?

i found question had answer question of performing batch conversions pandoc, doesn't answer question of how make recursive. stipulate front i'm not programmer, i'm seeking on here. the pandoc documentation slim on details regarding passing batches of files executable, , based on script looks pandoc not capable of parsing more single file @ time. script below works fine in mac os x, processes files in local directory , outputs results in same place. find . -name \*.md -type f -exec pandoc -o {}.txt {} \; i used following code of result hoping for: find . -name \*.html -type f -exec pandoc -o {}.markdown {} \; this simple script, run using pandoc installed on mac os x 10.7.4 converts matching files in directory run in markdown , saves them in same directory. example, if had file named apps.html , convert file apps.html.markdown in same directory source files. while i'm pleased makes conversion, , it's fast, need process files located in 1 directory...

i tried install yaml-cpp0.2.6 on oneric 11.10 server (on pandaboard / armel architecture). so used: $ hg clone http://code.google.com/p/yaml-cpp/ (which appers yaml-cpp0.5.0) $ mkdir build $ cd build $ cmake -dbuild_shared_libs=on .. $ make $ sudo make install everything without problem. unfortunately needed 0.2.6 version of it. therefore uninstall 0.3.0 version with: $ sudo make uninstall but gives me failure *** no rule make target `uninstall'. stop.' is there way uninstall it? or modify it, system don't need/want yaml0.2.6 anymore? the installer copies header files directory $prefix/include/yaml-cpp , library files $prefix/lib/libyaml-cpp.so . ( $prefix /usr/local ) just remove header directory , library files , should uninstalled.

i know basic question but. i understand concept behind. n++, ++n, n--, --n. however public static void main(string[] args){ int count = 1; for(int =1;i<=10;++i){ count = count * i; system.out.print(count); } } so print: 1 2 3 4 5 6 7 8 9 10. my question is. why if incremented ++i isnt treated 2, instead of 1. inst point of ++i, increment before it's manipulated operation? is point of ++i, increment before it's manipulated operation? the difference between ++i , i++ matters when it's used part of bigger expression, e.g. int j = ++i; // increment use new value assignment int k = i++; // increment, use old value assignment in case operation occurs @ end of each iteration of loop, on own . loop equivalent to: int count = 1; // introduce new scope i, loop { // declaration , initialization int = 1; // condition while (i <= 10) { count = count * i; system.out.print(count); /...
