Function documentation
static void inciter::
Configure Charm++ custom reduction types initiated from this class.
This routine is supposed to be called from a Charm++ initnode routine. Since the runtime system executes initnode routines exactly once on every logical node early on in the Charm++ init sequence, they must be static as they are called without an object. See also: Section "Initializations at Program Startup" at in the Charm++ manual http:/
bool inciter::
Compute diagnostics for density-based solvers.
| Parameters | |
|---|---|
| d in | Discretization proxy to read from |
| u in | Current solution vector |
| un in | Previous solution vector |
| diag_iter in | Diagnostics output frequency |
| Returns | True if diagnostics have been computed |
Diagnostics are defined as some norm, e.g., L2 norm, of a quantity, computed in mesh nodes, A, as ||A||_2 = sqrt[ sum_i(A_i)^2 V_i ], where the sum is taken over all mesh nodes and V_i is the nodal volume. We send multiple sets of quantities to the host for aggregation across the whole mesh. The final aggregated solution will end up in Transporter::diagnostics(). Aggregation of the partially computed diagnostics is done via potentially different policies for each field.
