Worked locally with 4 chips fsdp=4:
export PJRT_DEVICE=TPU; export TORCHPRIME_TPU_TYPE=v6e-4 && python torchprime/torch_xla_models/train.py model=flex-qwen-1bMFU: 0.21
On a v5p-128 cluster with command
tp run --name jialei-0812-qwen-fsdp32tensor2 torchprime/torch_xla_models/train.py model=flex-qwen-1b task.global_batch_size=64 ici_mesh.fsdp=32 ici_mesh.tensor=2
