PyTorch-Native Stack for Agents
summary
A PyTorch-native RL stack that actually ships orchestration, RDMA weight sync, and environment tooling: TorchForge for actor-based rollout/trainer orchestration built on Monarch’s actor meshes and supervision trees; TorchStore as an in-memory tensor KV store that uses RDMA and DTensor resharding to push terabyte-scale checkpoints without bloating GPU memory; and OpenEnvironments to share gym-like containers plus reward/eval pipelines. Validation runs on a 512 H100 cluster with 3.2 Tb/s InfiniBand confirm stability and large-scale throughput.
