I have opened a discussion group for the Multicore package on Yahoo. Please join and discuss with other users!

09 Feb 2009 PlotAxisAtOrigin This is a 2D vresion of Plot3AxisAtOrigin, which may be used to plot axis at origin. Author: Shanrong Zhang

Sorry, but I think this package is not very useful. On the first view it looks nice, but the axis will not change when zooming in etc.

Very nice, for version 2.0 you could animate the snow flakes :-)

04 Nov 2009 Multicore - Parallel processing on multiple cores This package realizes parallel processing on multiple cores/machines. Author: Markus Buehren Karl

Hi Markus,

first of all -- you've developed a great tool that helps me a lot with my simulations in the field of audio signal processing. Seeing my dual quad core at 100% (instead of 13%) load warms my heart :).

Well, I'm not sure whether I'm getting something wrong here, but I had some problems when the function that is executed by the multicoremaster() (and the slaves) has more than one return value. It seems that in this case all but the first return values get lost. I applied a little trick that I found out about some time ago to solve this problem:
Everytime that feval() is called (in startmulticoremaster() and startmulticoreslave() ) I added something like this:

N_returnValues = nargout(functionHandleCell{k});
clear('returnValue'); % this is dirty! The next call doesn't work
     % without clearing "returnValue" beforehand if
     % N_returnValues==1. If it's greater->no
     % problem (even without clearing
     % "returnValue")
[returnValue{1:N_returnValues}] = feval(functionHandleCell{k}, parameterCell{k}{:}); % ha!
resultCell{k} = returnValue;

Doing so, the resultsCell that is returned from startmulticoremaster() is always a cell -- even if the called function has only one return value...

I hope this is of any value to anybody and that I'm not causing trouble by posting this hack :). I'm always open to learn a better solution....

Cheers, and thanks again for Multicore!

Thank you very much for this great tool! I started using your code a few of months ago, and I must say it saved me lots of hours of work.

28 Sep 2009 Multicore - Parallel processing on multiple cores This package realizes parallel processing on multiple cores/machines. Author: Markus Buehren Wunsch, Johannes

Awesome tool, I use it for fitting a computationally expensive financial model and it works just great. Thanks a lot for publishing it!! Johannes

16 Sep 2009 Multicore - Parallel processing on multiple cores This package realizes parallel processing on multiple cores/machines. Author: Markus Buehren Amir

I have little bit of problem running the master and slave processes over the network. I am not sure how to share the folder over a linux network!
Anybody can help?
