For example, if one wanted to use node-1 as their admin node, node-2 and node-3 as client nodes, and node-4 and node-5 as their server nodes then these variables would be defined as:

Code Block
ADMIN_NODE=node-1
CLIENT_NODES=node-2, node-3
SERVER_NODES=node-4, node-5
ALL_NODES=$ADMIN_NODE,$CLIENT_NODES,$SERVER_NODES

...

export OFI_INTERFACE=eth0
export CRT_PHY_ADDR_STR="ofi+sockets"
