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

[Sean Ryan Leventhal <sleventh@xxxxxxxxxxxx>]

The sample beginning with bash-2.03#... contains everything that prints 
out.  Opal continues running without printing error messages.  I had been 
using the default opal parameters, but I have copied them below in case 
there is a misunderstanding here:
