This commit adds a new public member function
SatfuncConsistencyChecks<>::collectFailures(root, comm)
which aggregates consistency check violations from all ranks in the
MPI communication object 'comm' onto rank 'root' of 'comm'. This
amounts to summing the total number of violations from all ranks and
potentially resampling the failure points for reporting purposes.
To this end, extract the body of function processViolation() into a
general helper which performs reservoir sampling and records point
IDs and which uses a call-back function to populate the check values
associated to a single failed check. Re-implement the original
function in terms of this helper by wrapping exportCheckValues() in
a lambda function. Extract similar helpers for numPoints() and
anyFailedChecks(), and add a new helper function
SatfuncConsistencyChecks<>::incorporateRankViolations()
which brings sampled points from an MPI rank into the 'root's
internal data structures.
One caveat applies here. Our current approach to collecting check
failures implies that calling member function reportFailures() is
safe only on the 'root' process in a parallel run. On the other
hand functions anyFailedChecks() and anyFailedCriticalChecks() are
safe, and guaranteed to return the same answer, on all MPI ranks.
On a final note, the internal helper functions are at present mostly
implemented in terms of non-owning pointers. I intend to switch to
using 'std::span<>' once we enable C++20 mode.
