+        The GRU is a hardware resource located in the system chipset. The GRU
+        contains memory that can be mmapped into the user address space. This memory is
+        used to communicate with the GRU to perform functions such as load/store,
+        scatter/gather, bcopy, AMOs, etc.  The GRU is directly accessed by user
+        instructions using user virtual addresses. GRU instructions (ex., bcopy) use
+        user virtual addresses for operands.

+        If you are not running on a SGI UV system, say N.
