Function documentation
void inciter::Transporter:: load(std::size_t nelem,
std::size_t npoin)
Reduction target: the mesh has been read from file on all PEs.
Parameters  

nelem in  Total number of mesh elements (summed across all PEs) 
npoin in  Total number of mesh nodes (summed across all PEs). Note that in parallel this is larger than the total number of points in the mesh, because the boundary nodes are doublecounted. 
void inciter::Transporter:: refinserted(int error)
Reduction target: all PEs have created the mesh refiners.
Parameters  

error in  aggregated across all PEs with operator max 
void inciter::Transporter:: compatibility(int modified)
Reduction target: all mesh refiner chares have received a round of edges, and ran their compatibility algorithm.
Parameters  

modified in  Sum acorss all workers, if nonzero, mesh is modified 
This is called iteratively, until convergence by Refiner. At this point all Refiner chares have received a round of edge data (tags whether an edge needs to be refined, etc.), and applied the compatibility algorithm independent of other Refiner chares. We keep going until the mesh is no longer modified by the compatibility algorithm (based on a new round of edge data communication started in Refiner::
void inciter::Transporter:: matched(std::size_t nextra,
std::size_t nref,
std::size_t nderef,
std::size_t initial)
Reduction target: all mesh refiner chares have matched/corrected the tagging of chareboundary edges, all chares are ready to perform refinement.
Parameters  

nextra in  Sum (across all chares) of the number of edges on each chare that need correction along chare boundaries 
nref in  Sum of number of refined tetrahedra across all chares. 
nderef in  Sum of number of derefined tetrahedra across all chares. 
initial in  Sum of contributions from all chares. If larger than zero, we are during time stepping and if zero we are during setup. 
void inciter::Transporter:: bndint(tk::real sx,
tk::real sy,
tk::real sz,
tk::real cb)
Compute surface integral across the whole problem and perform leaktest.
Parameters  

sx in  X component of vector summed 
sy in  Y component of vector summed 
sz in  Z component of vector summed 
cb in  Invoke callback if positive 
This function aggregates partial surface integrals across the boundary faces of the whole problem. After this global sum a nonzero vector result indicates a leak, e.g., a hole in the boundary, which indicates an error in the boundary face data structures used to compute the partial surface integrals.
void inciter::Transporter:: refined(std::size_t nelem,
std::size_t npoin)
Reduction target: all PEs have optionally refined their mesh.
Parameters  

nelem in  Total number of elements in mesh across the whole problem 
npoin in  Total number of mesh nodes (summed across all PEs). Note that in parallel this is larger than the total number of points in the mesh, because the boundary nodes are doublecounted. 
void inciter::Transporter:: resized()
Reduction target: all worker chares have resized their own data after mesh refinement.
void inciter::Transporter:: comfinal(int initial)
Reduction target indicating that the communication maps have been setup.

tk::real initial)
Reduction target summing total mesh volume.
Parameters  

v in  Mesh volume summed across the whole problem 
initial in  Sum of contributions from all chares. If larger than zero, we are during time stepping and if zero we are during setup.
