What: /sys/firmware/sgi_uv/
Date: August 2008
Contact: Russ Anderson <rja@sgi.com>
Description:
The /sys/firmware/sgi_uv directory contains information
about the SGI UV platform.

Under that directory are a number of files:

partition_id
coherence_id

The partition_id entry contains the partition id.
SGI UV systems can be partitioned into multiple physical
machines, which each partition running a unique copy
of the operating system. Each partition will have a unique
partition id. To display the partition id, use the command:

cat /sys/firmware/sgi_uv/partition_id

The coherence_id entry contains the coherence id.
A partitioned SGI UV system can have one or more coherence
domain. The coherence id indicates which coherence domain
this partition is in. To display the coherence id, use the
command:

cat /sys/firmware/sgi_uv/coherence_id
