Re: [Gems-users] Completing SPLASH benchmarks with opal

[Luke Yen <lyen@xxxxxxxxxxx>]

Sean,

   It seems a number of people have been experiencing a similar problem.
I noticed you have the Simics output but not the Opal output.  Are there any
messages that Opal dumps before it crashes?  Also, can you give me some
info on the Opal configuration parameters you are using?

  Thanks,
    Luke
