SPEC2006 CPU trace file

[Hsing-Min Chen]

hello, 

I am a new user of macsim and I am using it to plot MPKI for L3 cache to study.

I download the spec trace file from the websit (5M insts. given from your group) and I test sjeng to get MPKI around 0.5 (which is correct).

However, if I generate the trace file by myself, I get MPKI around 40 (which is definitely wrong).

My macsim version is 2.04

My pin version is pin-2.12-56759

I use the following command line to generate trace file:

../../pin-2.12-56759-gcc.4.4.7-linux/pin.sh -injection child -t /home/hmchen/macsim-2.04/tools/x86_trace_generator/obj-intel64/trace_generator.so -max 60000000 -- ./sjeng_base.amd64-m64-gcc42-nn ref.txt

your reply will be highly appreciated

Thanks!

Hsing-Min

Hello Hsing-Min,

We use SimPoint to generate a representative slice of instructions for each benchmark. So the 5M instructions provided is not the first 5M instructions.

Sincerely,

Hi Hyojong,

Thanks for your reply.

I use SimPoint to get the number of skip instructions and use the representative ROI region to run the experiments. Finally, I get the correct results.
