Hi Nilay, Yes, I've taken a look at the ruby.stats file. I'm a little confused about some naming issues, like: Request_type_LD, request_type_ST and request_type_ATOMIC, what is the difference of them?
Also in the ruby.stats file, there is only average network latency which defined as: network_latency/flits_received. I want to find the request/packet latency sent out by L1 cache into the network. Actually I looked into the code like Sequencer.cc and port.cc, but still got no clue.
