Rearrange halo search #54

Closed streeve closed 8 months ago

streeve commented 8 months ago

Performance improvement (checked on GPU) and simplification of particle halo search. Should enable better reuse for contact ghost neighbors

streeve commented 8 months ago

Speedups using the current crack branching and elastic wave with double the size per dimension. "Other" speedup is possibly unrelated
