This branch will add the ability to log the source cpu for memory requests in dramsim2
Some bookkeeping
Added the source cpu in the transaction object and modified the

should be able to implement PAR-BS
Finished PAR-BS implementation and added the required modifications to enable benchmark execution
Fixing some issues...
Still fixing things
Merged the par-bs code in the dramsim2 branch
