Maximum Number of Independent MATLAB sessions I can run on MY PC

Hey,

what is the maximum number of MATLAB sessions I can run on my i7 8GB dell computer, I was able to run 15. But I'm afraid my results might not be right?

Any suggestions

Hundreds, maybe thousands, if you can increase the memory (e.g., swap file.) Your system might end up getting so slow as to be practically unusable, but if you do this will be an OS issue rather than a MATLAB issue.

There is no hard limit, but you run a greater and greater risk of running out of physical memory. This will cause your computer to fall back to virtual memory, which will kill the performance of MATLAB and other applications. The results would likely still be correct, but you'd need to wait a long time for your answers (possibly even longer than just running your 15 programs sequentially).

Are you running Windows? Keep your Task Manager open and be wary if system memory usage pushes past 8GB.

Ken, from a licensing perspective, what's the difference between doing this and running n Parallel Computing labs? I sometimes wish I could have more labs on my local machine to test algorithms, but of course run into the limit of 12 ...

Actually, I'll ask this as a new question - if you see this, kindly respond there!

Thanks a lot Ken & Walter, totally appreciate your answer, I was actually following up with memory which I did upgraded couple of days ago. Yes, I'm running windows 7 and my sessions doesn't go over 8 GB.

Thanks again for your feedback.
