TSP-Link network group functions
Group number Group members Present function
0 Master node Initiates and runs a test script on node 2
Initiates and runs a test script on node 6
1 Group leader
Node 2
Runs the test script initiated by the master node
Initiates remote operations on node 3 through node 5
Node 3 through node
5
Performs remote operations initiated by node 2

Node 6 Runs the test script initiated by the master node
Initiates remote operations through node n
Node n Performs remote operations initiated by node 6
Using groups to manage nodes on TSP-Link network
The primary purpose of a group is to assign each node to run different test scripts at the same time
(in parallel). Each node must belong to a group; a group can consist of one or more members. Group
numbers are not assigned automatically; you must use remote commands to assign each node to a
group.
Master node overview
The master node is always the node that coordinates activity on the TSP-Link
®
network. All nodes
assigned to group 0 belong to the same group as the master node.
The following list describes the functionality of the master node:
• The only node that can send the execute() command on a remote node
• Cannot initiate remote operations on any node in a remote group if any node in that remote group
is performing an overlapped operation
• Sends the waitcomplete() command to wait for the local group that the master node belongs
to, to wait for a remote group, or to wait for all nodes on the TSP-Link network to complete
overlapped operations
