Re: [Gems-users] 64 cores on gems 2.1.1 with simics 3.0

[wckwon@xxxxxxxxxxxxx]

 I'm using the protocols as provided by Ruby without any modification.
 In fact, with the same configuration and checkpoint, it worked well  
on Gems 2.1 + Simics 2.2 . Now on Gems 2.1.1 + Simics 3.0, I cannot  
run it due to the mentioned errors.
 I'm simulating abisko-serengeti with solaris 10 - sparc v9.
