 ### Cluster Launch Control Pipeline Class
 
-Please refer to the `PipelineCLCFetchAsync` pipeline class defined in [Cluster launch control pipeline class](https://github.com/NVIDIA/cutlass/tree/main/include/cutlass/pipeline/sm100_pipeline.hpp). Cluster launch control queries can be pipelined and mananged by an asynchronous pipeline with producer-consumer relationship (See

Cluster launch control queries can be pipelined and managed by an asynchronous pipeline with producer-consumer relationship (See
 [pipeline](pipeline.md) document). The producer is the scheduler warp of the 0th CTA in the cluster and the consumers are all warps that need `ClcID`s. 
 
 To setup a CLC pipeline correctly, we need to make sure the params are set to the right values:
