2719: BH-gpu magnetostatics: multiple CPU support and refactoring r=fweik a=psci2195 Fixes #2500 In general, this fix is important cause it allows a user to parallelize both CPU and GPU calculations: EOM integration and magnetostatics respectively. Description of changes: - Correct dipole prefactor broadcasting among the nodes - New test dds-and-bh-gpu.py is running over 4 CPUs: a comparison between BH and DDS gpu calculations. A new test has been needed because we cannot use dds-cpu as a baseline cause it does not support multiple CPUs. - Some technical debt has been caught up here as well: smart pointers based BH, the AMD GPU skip cleanup, per node test seeding. PR Checklist ------------ - [ ] Tests? - [ ] Interface - [ ] Core - [ ] Docs? Co-authored-by: Bogdan Tanygin <[email protected]> Co-authored-by: Brian Tanygin <[email protected]>
