How to run the scheme, i.e. '.json' file, synthesized by SCCL on NCCL ? #50

I use SCCL to synthesize a step=3 alltoall algorithm on topology DGX-1 whose name is ’Alltoall.n8-DGX1-steps3.msccl.json‘. But how can I actually run it on NCCL ? Can you give me an example or a document about how to actually run a synthesized scheme ? Thanks a lot !

Try msccl ncclize <file.json>
