Hi
Yesterday, I created a SPEC_CPU2006.qcow2 image disk based on
ubuntu-natty.qcow2 provided from MARSSx86 official website. I installed CPU
2006 files on '/root/' directory to make simulations easy with 'start_sim,
stop_sim, kill_sim'.
After the installation was completed, I followed CPU2006 documentation to
build and run the workloads. The build operations were completed without
any errors, and I used 'runspec' command as follows.
./start_sim ; runspec --config=myconfig.cfg --size=ref --noreportable
--iterations=1 bzip2; ./stop_sim ;./kill_sim
also, I ran all workloads based on that command lines. (additionally, I
specified stopcycle 100M and single_core, )
However, today, when I check the simulation results, I show some strange
results. All IPC results in log files are similar. To show what I say, I
give you some IPC results as follows.
GemsFDTD lbm wrf sphinx3
h264ref gcc libquantum
user 0.97849 0.97876 1.01513 0.97197 0.96678

0.87850 0.89806
(other workloads also have similar results)
Recently, when I used parsecROI.qcow2, all workloads show different IPC
results. I give you PARSEC workloads' IPC results (I ran the workloads with
10B cycles and single_core).
swaptions fluidanimate vips freqmine
user 1.14556 1.28826 1.71456 1.12002

total 1.13923 1.27027 1.64984 1.10204
With the PARSEC results, I can't be sure that the SPEC CPU2006 disk I made
is operated correctly, and I don't know what I missed if there are some
problems. So, I want you to answer me about its correctness. If some
problems are, please let me know how to solve the problems.
Thanks in advance.
