bool NumLib::anonymous_namespace{NonlinearSolver.cpp}::assembledOnAllRanks

(

Assemble const &

assemble

)

Runs assemble and reconciles a NumLib::AssemblyException thrown by it across all MPI ranks.

Returns

Whether the assembly succeeded on every rank.

Do not remove the reconciliation across ranks: a rank that carried on while another one aborted would block in the collective calls of the subsequent linear solve and deadlock the simulation. The reconciliation itself is not covered by a test: the unit tests in Tests/NumLib/TestNonlinearSolverAssemblyException.cpp run on a single rank, and they are disabled in PETSc builds altogether (issue #1989).
