multithreading - Matlab parallel programming -

-

first of all, sorry general title and, probably, general question.

i'm facing dilemma, worked in c++ , right i'm trying similar 1 of previous projects, parallelize single-target object tracker written in matlab in order assign each concurrent thread object , gather results @ each frame. in c++, used boost thread api so, , results. possibile in matlab? reading around i'm finding rather unclear, i'm reading lot parfor loop that's pretty it? can impose synchronization barriers similar boost::barrier in order stop each thread after each frame , wait other before going next frame?

basically, wish initialize common data structures , launch few parallel instances of tracker, shares data , take different objects track input. suggestion appreciated!

parfor 1 piece of functionality provided parallel computing toolbox. it's simplest, , people find useful, why of resources research has found discuss that.

parfor gives way parallelize "embarassingly parallel" tasks, in other words tasks independent , not require communication between them (such as, example, parameter sweeps or monte carlo analyses).

it sounds that's not need. question, i'm not entirely sure need; since mention synchronization, barriers, , waiting 1 task finish before moves forward, suggest take @ features of parallel computing toolbox such labsend, labreceive, labbarrier, , spmd, allow implement more message-passing style of parallelization. there plenty more functionality in toolbox parfor.

also - don't afraid ask mathworks advice on this, there several (free) recorded webinars , tutorials on sort of parallelization can point towards.

hope helps!

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
