I resubmitted my application with the following:

Unfortunatly when it ran I received the following messages in the output 
file and unfortunately no counter info beyond MULTI__GET_TIME_OF_DAY:

Error adding Papi events!
The events you have chosed conflict.
This could be a limit on either the number of events
allowed by this hardware, or the combination of events chosen.
The papi layer calls are being disabled!
Deleting papiMCL in position: 1
Setting papi flags in counterUsed array to false ...
counterUsed[{1,2,3,5,6,7}] is now false ...
Finished disabling papi layer calls!

Obviously there is some conflict in my choices.  If I were a betting 
person I'd guess it was PAPI_BGL_OED.

Thoughts? Advice?

thanks,
