Hi all,
I have written a script to boot the ALPHA FS called spec2006.rcs: ---------------------------------------------------------------------------- ----------------------------------------------------- cd /spec2006/bin #/sbin/m5 switchcpu /sbin/m5 checkpoint 100000000 100000000 #/sbin/m5 dumpresetstats 100000000 100000000 ./bzip2_base.amd64-m64-gcc42-nn /spec2006/inputs/bzip2/input.program 280 /spec2006/inputs/bzip2/program.out & ./gcc_base.amd64-m64-gcc42-nn /spec2006/inputs/gcc/200.i -o /spec2006/inputs/gcc/200.s & ./mcf_base.amd64-m64-gcc42-nn /spec2006/inputs/mcf/inp.in /spec2006/inputs/mcf/inp.out & ./milc_base.amd64-m64-gcc42-nn /spec2006/inputs/milc/su3imp.in /spec2006/inputs/milc/su3imp.out & echo "Done :D" #/sbin/m5 exit #/sbin/m5 exit ---------------------------------------------------------------------------- ------------------------------------------------------- Afterwards, I restore from the checkpoints and run the simulation using the following command: ./build/ALPHA_MOESI_CMP_directory/gem5.opt configs/example/fs.py --cpu-type=detailed -n 4 --caches --l2cache --num-dir=4 --l1d_size=16kB --l1i_size=16kB -r 5 After a few seconds, I use "Ctrl+C" to break the simulation. However, the execution results indicate that the simulation has not been forwarded. (Most of the statistics are 0. And the switchcpu: numCycle result for each core is always 1. ) On the other hand, when I use a single-core configuration, there are some statistics and the simulation can be forwarded. Since in the checkpoint boot script the "/sbin/m5 switchcpu" is commended out, I guess that I cannot simulate a multicore configuration without setting switchcpu? On the other hand, I attempted to using the switchcpu in the spec2006.rcS, however, the gem5 always exits because of switchcpu. ---------------------------------------------------------------------------- ----------------------------------------------------- cd /spec2006/bin /sbin/m5 switchcpu /sbin/m5 checkpoint 100000000 100000000 #/sbin/m5 dumpresetstats 100000000 100000000 ./bzip2_base.amd64-m64-gcc42-nn /spec2006/inputs/bzip2/input.program 280 /spec2006/inputs/bzip2/program.out & ./gcc_base.amd64-m64-gcc42-nn /spec2006/inputs/gcc/200.i -o /spec2006/inputs/gcc/200.s & ./mcf_base.amd64-m64-gcc42-nn /spec2006/inputs/mcf/inp.in /spec2006/inputs/mcf/inp.out & ./milc_base.amd64-m64-gcc42-nn /spec2006/inputs/milc/su3imp.in /spec2006/inputs/milc/su3imp.out & echo "Done :D" #/sbin/m5 exit #/sbin/m5 exit ---------------------------------------------------------------------------- ------------------------------------------------------- Any advice will be appreciated. The attachment shows the stats with and without the "-n 4" configuration . Regards , Shuchang
