Cascadia K Matrix Dataset

Single HDF5 file split for Hugging Face (hard limit: 500 GB SI per file).

This is a dataset to be used with the AutonomousOED package: Zenodo, GitHub

This dataset can be used for reproducing results in the paper:

Sreeram Venkat, Stefan Henneking, and Omar Ghattas. "Sensor Placement for Tsunami Early Warning via Large-Scale Bayesian Optimal Experimental Design." arXiv preprint arXiv:2604.08812 (2026). To appear in Proceedings of SC'26.

Below are the instructions to reassemble the dataset before using it in the application.

Reassemble

cat cascadia_K_matrix.h5.part* > cascadia_K_matrix.h5

Parts are not valid HDF5 until concatenated in order (part0, part1, ...).

Original file: cascadia_K_matrix.h5
Dataset: /K_matrix — shape (252000, 252000), float64, chunks (420, 420)
