Each candidate setting of the model was scored one after another on the
coarse shell (a density, an FFT and an isotropic scale fit, 0.2-0.5 s
each), and a run with a model in another setting scores them in both of
its validations. They share nothing but what they read, so they now run
on ParallelFor, each on its own copy of the model, and are read back in
their own order: the log lines, the ranking and the tie-break (first of
equal R wins) are those of the serial loop.
Measured (16-core workstation, loaded): 8sa8 3 candidates 0.64 s ->
0.22 s; 9ea5 3 candidates 1.47 s -> 0.50 s; 8xtg 1.45 s -> 0.40 s.
p.mtz, the maps, the map MTZ and the placed model md5-identical.
