LinearSolveBench: magnetic diffusion development data

The 96 development cases for the magnetic_diffusion_flash family of LinearSolveBench.
Benchmark code, family manifests, the reference solver, and evaluation rules live in the code repository.

Dataset

These scalar magnetic-diffusion linear systems were captured from AlWire and two-dimensional driven ZPinch test-problems from FLASH 4.8.
These captures cover startup time steps and support independent linear solves, not complete simulation trajectories.
See the FLASH diffusion documentation for the underlying formulation.

Matrices are real float64 CSR, with 9,984–113,664 rows and 108,364–1,245,184 nonzeros.

Files

• cases/: one ZIP archive per development case. dimensions, and source-run provenance.
• README.md and LICENSE: dataset documentation and license.

Each cases/flash-replay-NNNN.zip contains exactly:

• matrix.npz: coefficient matrix A in SciPy CSR format.
• b.npy: captured right-hand side b.
• x0.npy: captured initial guess x0.
• case.json: tolerances, provenance identifiers, and file and numerical-array checksums.
