Yes you can change these values. The flit size is essentially the link width, and its default is 16B (128b), defines jn src/mem/ruby/network/garnet2.0/GarnetNetwork.py
src/mem/ruby/network/Network.py defines the default control message size which is 8B (64b). The default data message size is in src/mem/ruby/network/network.cc and is control msg size + cache block size , so (8+64)B = 72B Accordingly the number of control flits and data flits get computed. You can change any of these to model the number of flits per packet that you are interested in. Note — if you increase the number of control / data flits, you may need to increase the control and data VC depths accordingly in src/mem/ruby/network/garnet2.0/GarnetNetwork.py Cheers, Tushar On Jun 15, 2018, 2:36 AM -0400, F.

Faisal <dipu.7...@gmail.com>, wrote: Dear All, In the default garnet configuration, the default value of ni_flit_size = 16 results in control messages fitting within 1 flit, and data messages fitting within 5 flits. However, I would like to increase the number of data message flit size to 10 flits or the control message size to 5 flits. [In addition, I am also unsure about changing ni_flit_size to any value, can change the actual number of flit size in data packets or the control packets] Please let me know the possible configuration to perform such changes. Thanks in advance for your kindness. Thanks and best regards, F. A. Faisal --------------------------------- School of Information Science, JAIST Doctoral Student
