How to get it
OMat24 is hosted on Hugging Face Datasets at fairchem/OMat24 and mirrored in the FAIR-Chem repository. The canonical format is LMDB (one shard per split: train, val_id, val_ood). Total on-disk size is ~640 GB; plan for that plus a working buffer. No registration is required — the dataset is CC-BY 4.0. On a Garden-supported cluster, the data is already at /scratch/.../garden-cache/datasets/omat24 and Rootstock will pick it up.
