Opening multiple MATLAB windows in PC

May I open a few MATLAB windows in PC to run the same piece of program? Will it be of any conflicts to the results produced? I would like to run my program with different settings for each variable. So I create a universal template to enter different set of variables. I create a few files with different file names and open a few MATLAB windows to run the program. It is possible to do in such a way? Please advise.

You can start as many Matlab programs as your license allows. Running the same M-functions will not cause any troubles as long as you do not try to write to the same files. E.g. changing the preferences of Matlab or any user-define preferences files inside the prefdir folder will cause conflicts for obvious reasons. So if you keep care for such problems, running Matlab multiple times on a multi-core machine is an efficient method.

When accessing the hard disk or the network is the bottleneck, a parallel processing will not be much faster then a sequential processing.

Thank you for the answers Sir. Related to my earlier question, for the same piece of program, if I run it using both MATLAB R2010a and MATLAB R2012a, does it matter? will it be of any conflicts to the results produced? same question, can I run the same piece of program using different unit of PCs?
