"Finally, we implement a `NVMegatronRayWorkerGroup`, within which we create a Megatron and then run a tensor parallel (tp) split Llama mlp layer. Here, we use a complex dispatch mode, `Megatron_COMPUTE`. This dispatch mode assumes that user passes the data partitioned by DP dimension. The data is dispatched to all tp/pp ranks within the same dp group, and ultimately only collects output data from tp=0 and the last pp. In this way, for users that only write code on the driver, the Megatron behind the RPC becomes transparent."
