摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating efficient compiled code. In an example method, a compilation system obtains an un-optimized computational graph comprising a plurality of nodes representing operations and directed edges representing data dependencies. The un-optimized computational graph is analyzed using pattern matching to determine fusable operations that can be fused together into a single fusion operation. The un-optimized computational graph is transformed into an optimized computational graph by replacing the nodes representing the fusable operations in the un-optimized computational graph with a fusion node representing the single fusion operation. The compilation system produces efficient code by translating the fusion node of the optimized computational graph as a call that performs the fused operations.
