walker::Integrator class

Integrator Charm++ chare used to advance differential equations in time.

Constructors, destructors, conversion operators

Integrator(CProxy_Distributor hostproxy, CProxy_Collector collproxy, tk::CProxy_ParticleWriter particlewriterproxy, uint64_t npar) explicit: Constructor.
Integrator(CkMigrateMessage*) explicit: Migrate constructor.

void setup(tk::real dt, tk::real t, uint64_t it, const std::map<tk::ctr::Product, tk::real>& moments): Perform setup: set initial conditions and advance a time step.
void ic(): Set initial conditions.
void advance(tk::real dt, tk::real t, uint64_t it, const std::map<tk::ctr::Product, tk::real>& moments): Advance all particles owned by this integrator.
void out(): Output particle positions to file.
void accumulate(): Start collecting statistics.
void accumulateCen(uint64_t it, tk::real t, tk::real dt, const std::vector<tk::real>& ord)

Constructor.

Parameters
