[Gems-users] how to reproduce the experiment like LogTM or any other TMs

[ruzhu kao <kaoruzhu@xxxxxxxxx>]

Hi all:
    I am a newbie using GEMS. After I have read some papers about TM,
I find it is a very interesting topic that attracted me very much. So
I want to reproduce a testbed for me to quickly learn some merits of
TM. However, I have met many problems after I start to do some actual
work about TM.
   My software environment include: CentOS4.7, Simics 3.0.31, GEMS 2.1
   1. When I use naked-check-create.sh to create a naked checkpoints
as a beginning, it failed again and again.( I have already edited
"system.conf" with correct path and OS images. ) I noticed someone has
counted the similar problem and post to this list, but when I try to
use their advices, I failed again. It really make me dispirited. I
hope someone could indicate me a more detail solution.

   2. Then I use OS setup scripts contained in Simics, then I had done
OS setup. When I want to reproduce some TM system such as LogTM, I
have no idea about how to do that. I want to repeated just like ISCA05
tutorial, but I don't know how to produce a checkpoint which contains
some microbenchmarks in it. It seems need a script to do some
instructions like workload-check-create.sh. However I failed using
nake-check-create.sh, so I have no idea how to use
workload-check-create.sh Then I begin to read each README file in
GEMS. But I do not find proper solution. Does anybody could tell me
how to reproduce a TM system like LogTM, I think I may miss some
important steps.

I think I need your kindly and patient help to explain how to using
GEMS. Much appreciate for your valuable comments.
