Re: [Gems-users] does simics processor number need to match ruby processor number?

["ayu" <ayu@xxxxxxxxxxxxx>]

Well, what I'd like to do is simulate both shared and distributed memory
that uses many number of processors and allow it to share the data. Of
course that entails me writing/modifying the software to suit my needs.
However, if I run on a uniprocessor target machine can I use ruby to
simulate any number of processors that I need? 

Thanks,
Andy
