  their owning-slice. Chip coordinates map 1:1 to the physical TPU chips
  deployed in their owning slice.

  Fields:
    customTrafficMatrix: Custom generator syntax used to represent chip-chip
      granularity traffic matrix (TM) that is too large to be reasonably
      represented as a simple adjacency list.

      functionally equivalent to a slice-to-slice, all-to-all traffic matrix
      where each slice sends the same amount of traffic to all other slices.
      Notes: - Borg uses this default-generated traffic matrix to achieve
      best-effort, superblock-compact placement for the affinity group. - Borg
      may or may not report default-generated demands to the Datacenter
      Network for proactive provisioning; to depend on this behavior use an
      alternate representation such as `slice_to_slice_adjacency_list`. - This
      representation is likely a good fit for "small" workloads (e.g. 4 VLP
      slices) that wish to benefit from best-effort superblock colocation
      without needing to provide a detailed traffic matrix. - This option is
      likely not a good fit for "large" workloads with non-uniform traffic
      patterns (e.g. a 100 VLP slice workload with 10 data parallel replicas
      communicating in an all-to-all pattern and 10 pipeline stages
      communicating in a bidirection ring pattern), as it does not give Borg
      enough detail on which of the slices should be colocated in the same
      superblock as other slices. At the largest (e.g. cell-wide) scale, this
      devolves into "random" placement.
    sliceToSliceAdjacencyList: Adjacency list representation of a slice->slice
      granularity TM. Slice-to-slice encoding assumes traffic flows out of
