+ ---help---
+ 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.
