Hello, I have run a client-server program, use the sample fs.py (2GHZ atomic cpu with 512MB memory)and have the following questions about the simulation statistics.
1) eth0: 1000F mbps what does the 'F' stand for? full duplex? Can I think it means the bandwidth between client and server is 1000mbps? However, in m5stats.txt, drivesys.tsunami.ethernet.rxBandwidth=19(bits/s) drivesys.tsunami.ethernet.totBandwidth=34(bits/s) testsys.tsunami.ethernet.rxBandwidth=15(bits/s) testsys.tsunami.ethernet.totBandwidth=34(bits/s) Does anybody explain the above numbers? 2) drivesys.cpu.not_idle_fraction=0.000894 drivesys.cpu.numCycles=544382753 drivesys.cpu.num_insts=544372834 host_inst_rate=861547(inst/s) host_seconds=1266.56 host_tick_rate=240466519018(ticks/s) sim_freq=1000000000000(ticks/s) sim_insts=1091201381 sim_seconds=304.565430 sim_ticks=304565430390500 testsys.cpu0.not_idle_fraction=0.000898 testsys.cpu0.numCycles=546839739 testsys.cpu0.num_insts=546828547 Why are both not_idle_fractions so low? about 0.089%? What is the difference between host_tick_rate and sim_freq? What is the difference between host_seconds and sim_second? How to compute the time(seconds) used to execute instructions on each system? I have tried host_inst_rate to be divided by testsys.cpu0.num_insts. However, the result is more than double sim_seconds.
