Hi everyone,
I have a Linux 2.6.18-308.1.1.el5 x86_64 machine and I am tring to run
Parsec benchmarks on X86 full system mode. I followed the necessary
documentation for full system mode, downloaded the Linux kernel image and
Parsec disk image involving precompiled binaries (
http://www.cs.utexas.edu/~parsec_m5/) .
I was able to boot up a linux system, try a few commands and able to see
the Parsec directories on the disk. Next, i generated the run scripts using
the code provided on the same link.
However, when i try running them, I get a segmentation fault after the
message *"[HOOKS] Entering ROI"*. This happens for blacksholes, facesim,
ferret and swaptions.
*My run command is:*
./build/X86/gem5.opt --outdir=RUNS/m5out_blackscholes
./configs/example/fs.py
--disk-image=/home/fkaplan/Stravinsky/gem5/full_system/disks/x86root-parsec.img
--kernel=/home/fkaplan/Stravinsky/gem5/full_system/binaries/x86_64-vmlinux-2.6.28.4-smp
--script=./blackscholes_4c_simsmall.rcS
*My runscript is:*
#!/bin/sh
# File to run the blackscholes benchmark
cd /parsec/install/bin
/sbin/m5 switchcpu
/sbin/m5 dumpstats
/sbin/m5 resetstats
./blackscholes 4 /parsec/install/inputs/blackscholes/in_4K.txt
/parsec/install/inputs/blackscholes/prices.txt
echo "Done :D"
/sbin/m5 exit
/sbin/m5 exit
*The error message i get at the end of the terminal log:*
......

Do you have any idea what may have caused this? Let me know if you need any
other info such as logs stats etc. I am pretty new at gem5 and looking
forward to your help.
Best,
Fulya
