Re: [Gems-users] TM - runtime error

[holey003@xxxxxxx]

Ok.. But I got this value from conswtch.simics script where no. of threads 
are 2*processors-2. If I make it 3, I can't see debug messages for 
transactions, which means callback to simics from benchmark having those 
macros, e.g. BEGIN_WORKLOAD_TRANSACTION, are not working. Why would they 
work when number of threads are more?
