Re: [Gems-users] setting up 64 processors

[Hemayet Hossain <hossain@xxxxxxxxxxxxxxxx>]

So far I know the ids of the processors are not in sequence and those 
are shared with io boards. For every 32 is first 24 assigned for 
processors and next 8 for io. So in your case the ids of the processors' 
should be like 0...23 then 32..55 then 64...79.
