Hello all,

I have a problem with running CPU 2006 benchmark suite

Other benchmark suite (e.g., Splash2, npb, local) runs succefully and difference between CPU 2006 benchmark suites is that red command. Only CPU 2006 benchmark suite points other directory (Directory where CPU 2006 benchmarks are stored is /home/kyeonghoon/snipersim/benchmarks/cpu2006/)
Is there anyone who can solve this problem?

Thank you!

Lim Kyeonghoon,

There is a good reason for why the binary is pointing to a temporary directory. You can take a look at the source [1] to see that we create a new temporary directory and link to the appropriate files back in the original directory. To take a look at what is happening, you might want to comment out the cleanup command [2] to view the symlinks. Then, you’ll probably be able to see what the root cause of the problem is. I suspect that it has something to do with the setup script. Take a look and tell us what is going wrong.

  Thank you for answering my question. I find that the reason why the benchmark doesn't run is that in the setup script the directory name is unclear.

In the cpu2006 directory, all execution binary is in the src directory. However, __init.py  line 259 only points to the 'exe' directory. 

Therefore, I revise this code to point to 'src' and change the binary's name from lbm to lbm_base.sniper-x86_64

Then it works.

Thank you!
