Server Node Hostnames

The NODE column lists the hostnames of the nodes that function as I/O servers for the parallel file system being defined. The example configuration in Example 7-5 shows two parallel file systems:

• pfs0 - three server nodes: node0, node1, and node2.

• pfs1 - two server nodes: node2 and node3.

Note that I/O server node2 is used by both pfs0 and pfs1. Note also that hostname node3 represents a node that is used as both a PFS I/O server and as a computation server--that is, it is also used for executing application code.
