Dear all,

I have encountered an issue, in which, in Windows 7 MATLAB automatically uses all the CPU cores while in Windows Server 2012 it runs only on a single core (very low usage of the CPU). I have all MATLAB packages installed and run the same M-file. Is it normal? Any solutions for the problem?

Thank you in advance

How did you determine that in Win Server 2012, only a single core is being used? Did this affect the performance of your script? I mean, does your .m code run slower in 2012 than in Win 7?

There is a way to force an application to use certain cores by setting a property called 'CPU affinity':

Can you try this?
