[Apache TVM Discuss] [Development/RFC] [RFC] Building a new reproducible benchmark for TVM

2020-11-20 Thread Lianmin Zheng via Apache TVM Discuss
## Motivation Currently, TVM lacks an up-to-date and reproducible benchmark. The only benchmark is hosted at [tvm/apps/benchmark](https://github.com/apache/incubator-tvm/tree/main/apps/benchmark). However, this benchmark is too old and has several flaws. 1. The results were obtained 2 years ag

@jcf94 @junrushao1994 Sorry, both of you don't understand my question correctly. I mean the original TE is a declarative language so it can know all transformation before it starts to generate low-level AST. But the new schedule primitives are done imperatively. In the original TE, we can shar

How is the compilation speed compared to the original TE? In Ansor/Autotvm, we have to compile a lot of schedules for feature extraction, so the speed of schedule transformation matters. Do you have any benchmark results? Intuitively, I think the original TE will be faster because it can do a
