[Barrelfish-users] OpenMP modifications for message passing

[Simon Peter]

Hi Shawn,

The NAS OpenMP benchmarks still use shared memory in Barrelfish. They 
serve as demonstration that we support shared memory applications on top 
of a message passing OS.

If you're interested in message passing versions of the NAS benchmarks, 
look into the usr/rcce directory, where we have the LU and BT benchmarks 
in their message passing version.
