Re: [Gems-users] Error Loading Ruby Module

["Datta, Kushal" <kdatta@xxxxxxxx>]

Hi Dan,

I double-checked it. Even though I read-configuration a checkpoint file (.conf), it is giving me a "Physical Memory object not found" error. Object phys_mem or phys_mem0 is not allocated.

  Hello,

    I have a similar problem as Kushal, however it is a slightly different
  case. I could not solve how to solve it. The problem is as follows:

  Well, what I would like to do is to store a checkpoint during my simulation
  where Ruby is also running.
  That's, I start simics with a checkpoint and load Ruby, set the parameters
  I want and start the simulation. Then I stop the simulation and write the
  simics configuration to a conf file. When I restart simics from this
  configuration simics gives the "Physical Memory Object not found" error.
  I guess simics tries to load ruby module before loading other parts of
  the checkpoint which are needed by ruby. Is there a turn around for this?
  Or should I run all my ruby simulations from the very beginning all the
  time and can not get intermediate checkpoints?

    Sorry for interrupting,

      Derin Harmanci
