Dear guys
For doing my thesis, I need to run PARSEC on GEM5. I used "Running PARSEC
2.1 on M5" report but in this way, I encountered to some problems.
Firstly, when I run every benchmark, I receive same output. I guess that
runscript.rcS file has a problem. you can see this file below:
#!/bin/sh
# File to run the blackscholes benchmark
cd /parsec/install/bin/sbin/m5 dumpresetstats
#./blackscholes 64 /parsec/install/inputs/blackscholes/in_64K.txt
/parsec/install/inputs/blackscholes/prices.txt
echo "Done :D"
/sbin/m5 exit
secondly, I need to
have a cache trace with CPU number for each cache access.
please guide me for solving these problems.thank you.

Hello
I've faced a problem during running PARSEC Multi-threaded benchmarks on gem5 in
"fs" mode.
I've ran PARSEC on a system with 4 cores:
./build/ALPHA/gem5.debug --debug-flags=Exec
--debug-file=/home/sobhan/Desktop/blackscholes.out
configs/example/fs.py --cpu-type="detailed" --caches --l2cache
--script=/home/sobhan/Desktop/script.rcS
-m 5000000000 --num-cpus=4
As you can see, I used "debug-flags=Exec" to see how threads run on different
cores.But in the trace file I've found that common instructions are running on
different cores and it seems that there is just one thread for running this
benchmark.
How can I run a Multi-threaded benchmark on a Multi-core processor, whereas
different threads run on different cores.
Here I present a part of my trace file to show that there are same instructions
run on all cores:
187500: system.cpu0 T0 : @sys_reset+81 : hw_mfpr IPR(0x140),r31
:IprAccess : D=0x0000000000000000
196500: system.cpu1 T0 : @sys_reset+73 : hw_mfpr IPR(0x140),r31

please help me.
