Node identification allocation in a multi-tile system with multiple derivatives

A method comprising:

• generating, by a first functional unit in an array of functional units connected via a mesh network, a message comprising a node identifier identifying a target functional unit in the array of functional units;
• transmitting, over the mesh network the message to a second functional unit in the array of functional units;
• and
• loading configuration registers of the second functional unit with the node identifier of the target functional unit responsive to receiving the message, wherein the node identifier comprises a first coordinate identifier and a second coordinate identifier identifying a location of the target functional unit in the array of functional units.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• generating a message comprising a node identifier identifying a target functional unit in an array of functional units;
• transmitting the message over a mesh network to a functional unit in the array of functional units;
• and
• loading configuration registers of the functional unit with the node identifier of the target functional unit responsive to receiving the message, wherein the node identifier comprises a first coordinate identifier and a second coordinate identifier identifying a location of the target functional unit in the array of functional units.
