Any reason this has not been merged? As context this also fixed an issue we have by saving a distributed checkpoint on a 8x16 and then loading it in other topology. |

@alanwaketan Do you have a sec to review? I'll also add @JackCaoG |

does this change needs to go into 2.4 release(branch cut was yesterday)? |

Yes, we should cherry-pick this. I'll open a PR. |

In create_read_items_for_chunk_list, the ReadItem's
dest_offsetsare set to index into the local shard. Despite this, we performed an translation from global to local indices. This caused issues restoring checkpoints with padded tensors, i.e. where the global tensor size is not evenly divisible by the shard size.We should instead rely on
dest_offsetsdirectly to narrow the local shards.
