Task #3370

Updated by Alan Gray 10 months ago

Umbrella task for follow-up improvements.

h2. Unification of code-paths across different types of step in do_force
* The GPU buffer ops/reduction kernel should grow a feature to do virial calculation based on the bonded and short-range nonbonded contribution to avoid having to fall back to CPU on virial steps.
Additionally, if there are any bonded interactions calculated on the CPU, these forces need to be transferred separately for the virial reduction on virial steps.
* Allow uniformity across search and non-search steps (ATM at search the xyzq fmt is generated in search and copied while non-ns steps do the conversion which leads to complexity).
