[GitHub] [tvm] mbs-octoml opened a new pull request, #12078: [Collage] CombinerRule and CandidatePartition::EstimateCost

mbs-octoml opened a new pull request, #12078:
URL: https://github.com/apache/tvm/pull/12078

   See https://github.com/apache/tvm-rfcs/blob/main/rfcs/0062-collage.md.
   
   We complete the PartitionRule sub-class hierarchy with the addition of
   CombinePartitionRule, which allows disjoint candidate partitions to be
   unioned based on simple rules.
    - By TOpPattern kind, eg a kOutElemwiseFusable and kBroadcast.
    - A tuple argument with injective fields.
    - The projection from an injective group (obviously of tuple type)
    - Combinations of the above.
   These let us mimic many common fusion strategies, including TVMs, so that
   the candidates explored during Collage search are as large as possible to
   expose possible fusion opportunities but no larger.
   
   Also completes CandidatePartition with the EstimateCost method, which is
   used during search to construct a stand-alone IRModule for latency estimation.
   
   Finish units tests for PartitionRule and CandidatePartition.

   CI failure is a flake.
