Tuning Workflow

You are advised to perform subgraph tuning and then operator tuning. The reason is that performing subgraph tuning first can generate the graph partition mode. After subgraph tuning is complete, the operators are partitioned into the final shapes. Operator tuning can then be performed based on the final shapes. If operator tuning is performed first, the shapes of the tuned operators are not the final shapes after operator partitioning. This does not meet the actual application scenarios.

Figure 1 shows the tuning procedure. Table 1 describes the detailed operations.
