[Gems-users] Completing SPLASH benchmarks with opal

[Sean Ryan Leventhal <sleventh@xxxxxxxxxxxx>]

I am currently having difficulty getting benchmarks to complete while 
running opal.  All of them complete on a 4-processor simulation using 
ruby.  However, when I add opal they do not (except FFT).  They all have 
to be left for a fair amount of time, and invariably get one of the 
following:

"Bus Error" (simics crashes)
 or something of the following form:
bash-2.03# ./OCEANCON -p4

Ocean simulation with W-cycle multigrid solver
   Processors                         : 4
   Grid size                          : 258 x 258
   Grid resolution (meters)           : 20000.00
   Time between relaxations (seconds) : 28800
   Error tolerance                    : 1e-07

panic: failed to stop cpu1

Has anyone seen this.  I have gotten nothing like it when running with 
only ruby, or running just simics.
