TbeReduceElemwiseFusionPass

Description

Performs UB fusion in the subgraph that meets the following patterns with a static shape.

Mode 1:

Mode 2:

Constraints

• When this fusion pattern is used for operators with a large number of compute instructions (such as cos and sin), the compilation time may be too long. In this case, you are advised to disable this fusion pattern.
• The constraints of mode 1 are as follows:
  • Only static scenarios are supported.
  • Elemwise1 is required and its quantity is 1.
  • CommReduce is required and its quantity is 1.
  • Elemwise2 and Elemwise3 are optional. Their counts may be zero, but if present, each type must not exceed five.
  • Elemwise2 and Elemwise3 cannot be multi-input nodes.
• The constraints of mode 2 are as follows:
  • Only static scenarios are supported.
  • CommReduce is required and its quantity is 1.
  • The number of Elemwise4 ranges from 1 to 5.
  • Elemwise4 cannot be a multi-input node.
