Hi, I suspect Nitish is using Ruby since Ruby "ignores" the number of channels. (look at configs/ruby/Ruby.py and configs/common/MemConfig.py) To have this done with Ruby, you may want to create an Xbar with multiple "memory channels" connected to it and then connect the Xbar to the directory's memory port.
