Modal Clusters 正式可用，通过 @modal.clustered 一行代码获取多节点 RDMA 集群

Modal announced that Modal Clusters are generally available to all workspaces, letting users request multi-node clusters through the single decorator @modal.clustered. The clusters provide InfiniBand RDMA communication at up to 6.4 Tbps, automatically configured for PyTorch and NCCL, with clusters starting within seconds and billed by the second. Modal also describes a new gang scheduler that places N nodes at once and RDMA support built into the gVisor runtime, with Decagon, 1x and Runway cited as users for trillion-parameter fine-tuning, world model pre-training and multi-node video inference.
