Re: [Gems-users] Old question is repeated: Initial checkpoints creation problem

["Dan Gibson" <degibson@xxxxxxxx>]

When last I checked, which was quite some time ago, Simics 2.2.19 was still available from Virtutech's website (www.simics.net), though it required some website spelunking. If that is not the case now, it would be good to know for sure.

Hi,

I met the same problem when I tried to generate "naked checkpoints" using the shell script in GEMS release.

Dan provided a quick solution. But I have a question: where and how can I get the version 2.2.19 of Simics?

Thanks.

In general, you should always use the most recent version if you can. We use 2.2.19 internally, so the most recent version of GEMS is fully compatible with Simics 2.2.19. But, you needn't bother interface GEMS to Simics 2.2.19 if you're only using Simics 2.2.19 to make checkpoints -- you can do your timing simulation under Simics 3.0.x.

Which version of GEMS would be better with simics 2.2.19? The setup for 2.2.X in the wiki points to a really old version (1.0).

Thanks,

    As I recall there is a huge difference in the machine
    specification between Simics 2.x and Simics 3.x. I suggest you
    make the checkpoints with 2.2.19, and then simulate using 3.0.30.


    Checkpoints are forward-compatible.

    I would recommend using 2.2.19, as that is the version the scripts
    were created on.  There is no patch for 3.x to my knowledge, though if
    you are feeling ambitious there are some comments in the current


    scripts indicating what needs to be done:)

    Thanks for the reply. Does anybody have patches for Simics3.0.x? Or would it
    be better to try simics 2.2.19 available on simics web-site for other


    compatibility issues?

    The scripts in their current form only support Simics 2.x

    Hi all,

    Sorry to bother for a potentially simple question. I tried to create


    checkpoints using the script provided in $GEMS/checkpoints
    (naked-check-create.sh) as explained in the README file of corresponding
    directory. In order to do that, I downloaded and tried both Solaris10


    (sol-10-u4-ga-sparc-v[1,2]-iso.zip) and Solaris Express
    (sol-nv-b79b-sparc-v[1,2]-iso.zip) cd images. I am getting the following
    warning and error after that.

    Machines based on serengeti_conf.py are only provided for backward


    compatibility. The new component based machines in simics/targets/
    are recommended instead.

    Serengeti configuration error:
    Unsupported cpu type: ultrasparc-iii+

    System info: gems2.0, simics3.0.30, x86_linux



    Should I try to get some earlier versions of Solaris? Or should I

    enforce

    cpu_class to be something like ultrasparc-iii? Basically, I only

    modified

    system.conf with necessary modifications but nothing else as mentioned

    in the

    README file.

    Abdullah
