There are two nodes, N1 and n2, and six tasks, T1 through t6. The document describes the inter-task communication costs and task execution costs on each node. It provides an example of a serial task assignment with a total cost of 58 and an optimal parallel assignment with a total cost of 38. The optimal assignment is found by creating a static assignment graph and determining a minimum cutset, which partitions the tasks such that the total execution and communication costs are minimized.
