Re: [Gems-users] regd creating checkpoints for workloads

Brinda,

If you know how many instructions you want to run, you can continue simics for 
this same number of steps:

c NUMBER_OF_INSTRUCTIONS

and then take a checkpoint. You can load from this checkpoint and then run
with Ruby/Opal for another number of steps. Please see the
$GEMS_ROOT/gen-scripts/mfacet.py script for how we do it with magic
instructions, but you can change the script to run for a certain number of
steps.
