Hi All,
I'm trying to use the run_bench.py script with the checkpoint_after.c script
to create checkpoints.
I'm using the Ubuntu-Natty.qcow2 image with the checkpoint_Afer.c script as
follows:
./FFT & ./checkpoint_After 1M First_Checkpoint
This is my utils file:
[DEFAULT]
marss_dir = /home/max/marrs/
util_dir = /home/max/marss/util/
img_dir = /home/max/DiskImage/
qemu_bin = /home/max/marss/qemu/qemu-system-x86_64
default_simconfig = -kill-after-run -quiet
[suite FFT]
checkpoints = First_Checkpoint
[email]
xoauth = something.txt
to = a991852 <at> hotmail.com
[run FFT_Final]
suite = FFT
images = /home/max/DiskImage/ubuntu-natty.qcow2
memory = 2G
simconfig = -logfile %(out_dir)s/%(bench)s.log
-stats %(out_dir)s/%(bench)s.yml
-machine atom_single_core
-stopinsns 1M
%(default_simconfig)s
However, when I tried running the script, it would generate a empty yml
file, this is the log file:

I created checkpoints by using:
./FFT & ./checkpoint_after 1M hello
or
./checkpoint_after 1M hello ; ./FFT ; ./stop_sim (appeared in micro 2012)
Then running the run_bench.py with the checkpoint appeared as above, but it
doesn't work.
Does anyone know why this happens?
Thanks
