Using groups to manage nodes on the TSP-Link network
The primary reason to use 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 nodes on
the TSP-Link network. Group numbers are not assigned automatically; you must use the
Instrument Control Library (ICL) 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 issue the execute command to 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
• Can use the waitcomplete command to wait for all overlapped operations running on
the local group that the master node belongs to, and to wait for all overlapped operations
running on a remote group, or to wait for all overlapped operations running on the TSP-
Link network to complete
Group leader overview
Each group has a dynamic group leader. The last node in a group running any operation initiated
by the master node is the group leader.
The following list describes the functionality of the group leader:
• Master node
• Initiates and runs a test script on
Node 2
• Initiates and runs a test script on
Node 5
• Initiates and runs a test script on
Node 6
• Group leader
Node 2
• Runs the test script initiated by the
master node
• Initiates remote operations on Node
3
• Node 3
• Performs remote operations initiated
by Node 2
• Group leader
Node 5
• Runs the test script initiated by the
master node
• Initiates remote operations on Node
4
• Node 4
• Performs remote operations initiated
by Node 5
• Group leader
Node 6
• Runs the test script initiated by the
master node
