Getting an error when trying to run parsec benchmark

[Dan Yee Ming Chung]

Greetings,

I am trying to run a simulation on x264 benchmarks from parsec-2.1 using the following commands:

yee@yee:~/sniper-6.1/benchmarks$ sudo ./run-sniper -n 2 -d /sniper-6.1/output_test -c nehalem.cfg --roi --viz --power --no-cache-warming --benchmarks=parsec-x264-small-2

but I get error shown below:

Now, based on the error (highlighted by red), I think it is missing roi code in the precompiled binary but still not sure. Is there any solution?
Currently, I am using an Intel Pentium G2020 with 16 GB of ram with Ubuntu 14.04.

Thank you.

Hi,

I have remake Sniper by following the tutorial at here :
https://groups.google.com/forum/#!topic/snipersim/7WJ1VR6a3zI

It is now working. I think making the parsec benchmarks with new version of perl is the benchmark runs with error.

Great, thanks.
