Hi all, I have been using a traffic injector to inject traffic into the mesh. However, I noticed that when I increase the injection rate, at some point it saturates and I cannot inject more traffic even though the mesh and memory bandwidth is not saturated. For this specific study, I am only injecting traffic from one of the cpus and when the injection interval is less than 3ns, I start seeing lots of retries. I am using the CHI protocol and the mesh frequency is set to 3GHz. On paper I should be able to inject one request every cycle, but if I go below one request every 6 cycles (3ns) I cannot inject more and only get retries. For instance: system.cpu00.data_sequencer.response_ports0: Request ReadReq for address 0xdf43623b did not issue because BufferFull Any thoughts?
Thanks, Amin
