Hi @tqchen and @zxybach,
cc : @mbaret What is a Composite Target ? TVM being a multi-target compiler, it would be a bit confusing to use a Array of Targets as another Composite Target -- I think its the terminology what is confusing here. A composite target sounds like a target that codegen intimately in a single codegen path for different devices rather than a structure that is used by TVM to trigger different codegen flows. I think we all agree we need a way to communicate this Options/Flags through out the lowering but I personally would not be in favor of attaching this to a (Composite) target -- that result in overloading the term "Target". [quote="tqchen, post:5, topic:11372"] We get the benefit of being able to tag, and record target [/quote] I believe we can still do it as the target is part of the CompilationConfig [quote="tqchen, post:5, topic:11372"] CompilationOption can appear as a field of sub-target of something else. Imagine that we need to offload a subgraph to another customized compilation, which may needs its own specification of the heterogenous “targets”. [/quote] CompilationConfig is supposed to contain attributes that are not specific to a target. Thus, they would be still accesible in the IRModule. Wont they ? [quote="tqchen, post:5, topic:11372"] Same API argument(Target) for both graph level compilation and operator level compilation. [/quote] This could also be said with respect to CompilationConfig being available for both graph level compilation and operator level compilation -- just that "targets" are part of CompilationConfig. In a summary what we need to discuss is : * What is the best term to use to structure that holds information/flags that are target independent and hold the set of targets in the same time? * Moreover, it would be great to reserve the term "Composite" target to a target that intimately codegen to multiple devices without divergence in the compilation pathway. --- [Visit Topic](https://discuss.tvm.apache.org/t/pre-rfc-compilation-configuration-representation/11372/6) to respond.
