A TPU v2 slice is composed of 512 chips interconnected with reconfigurable
high-speed links. To create a TPU v2 slice, use the --accelerator-type
flag in the TPU creation command (gcloud compute tpus tpu-vm). You specify the
accelerator type by specifying the TPU version and the number of TPU cores. For
example, for a single v2 TPU, use --accelerator-type=v2-8. For a v2 slice
with 128 TensorCores, use --accelerator-type=v2-128.
The following command shows how to create a v2 TPU slice with 128
TensorCores:
