Re: [Gems-users] number of processors

["Dave Z." <zhu_dave@xxxxxxxxx>]

It turns out the problem is in
SimicsDriver::exceptionCallback.
SIMICS_get_proc_no(cpuPtr) returns an unused processor
number which causes the error in my previous email.
So, this means the number of processors in Simics
should match the number of processors in Ruby, right?

Thanks,

Dave
