Hi, Udit
You might use a too big number of fast forwarding(-F 50000000000).
Try to use -F 50000000.

Subject: [gem5-users] GEM5 run with PARSEC blackscholes - Seems to be early
termination
Hello Users,
I am trying to run PARSEC benchmark "blackscholes", I used following command
./build/ALPHA_FS/gem5.opt ./configs/example/fs.py -n 64
--script=/design/hegcad/users/udit/MS/common/project/general/multi_core/PARSEC/blackscholes_2c_simsmall.rcS
--detailed --caches --l2cache -F 50000000000
blackscholes_2c_simsmall.rcS content is following, In this file I
disabled switchcpu to avoid unwanted termination during cpu switching
time.
#!/bin/sh
# File to run the blackscholes benchmark
cd /parsec/install/bin
#/sbin/m5 switchcpu
/sbin/m5 dumpstats
/sbin/m5 resetstats
./blackscholes 64 /parsec/install/inputs/blackscholes/in_4K.txt
/parsec/install/inputs/blackscholes/prices.txt
echo "Done :D"
/sbin/m5 exit
/sbin/m5 exit
As per Joel http://comments.gmane.org/gmane.comp.emulators.m5.users/3931,
this benchmark takes around 5 hours to complete the run but for me run
is completed with-in 15-20 minutes, I am not able to understand reason
for early termination of the run,.
On screen-output, it is showing me termination as follows
