I followed the instruction from utexas to download full system image and
parsec binary.
Then start a test run with command :
*
build/ALPHA/gem5.opt configs/example/fs.py
--disk-image=/home/jo/my-gem5/full-sy
stem/parsec/linux-parsec-2-1-m5-with-test-inputs.img
--kernel=/home/jo/my-gem5/f
ull-system/parsec/vmlinux_2.6.27-gcc_4.3.4 -n 4
--script=/home/jo/my-gem5/full-s
ystem/parsec/blackscholes_4c_simmedium.rcS --cpu-type=timing --caches
--l2cache
*
In rcS file
*
#!/bin/sh
cd /parsec/install/bin
/sbin/m5 dumpstats
/sbin/m5 resetstats
./blackscholes 4 /parsec/install/inputs/blackscholes/in_16K.txt
/parsec/install/
inputs/blackscholes/prices.txt
echo "Done :D"
/sbin/m5 exit
When I took a look of output status file*, all 4 cpus are idle for over
96% of time(idle_fraction). Is this result correct or I did something
wrong in any step? Thanks
